Spatial Econometric Modelsof Interdependence
Theory & Substance; Empirical Specification, Estimation, Evaluation; Substantive
Interpretation & Presentation
Talk prepared for Blalock Lecture on7 August 2008 at the ICPSR Summer School
based on the joint work ofRobert J. Franzese, Jr., The University of Michigan
Jude C. Hays, The University of Illinois
• Motivation: Integration & Domestic Policy-Autonomy– Does economic integration constrain govts from redistributing
income, risk, & opportunity through tax & spending policies?– In answering this & related questions, scholars have overlooked
spatial interdependence of domestic policies as important evidence.
– Economic integration generates externalities across political jurisdictions, which implies strategic policy interdependence, so policy of one govt will be influenced by policies of its neighbors.
• Interdependence Substance, Theory, & Empirics: Use contexts econ integration (& related) to explore & explain:– Substance: i’s actions depend on j’s. Examples.– Theory:
• General: externalitiesstrategic policy complements/substitutesrace-to-bottom/top/elseearly/late-mover advantagesstrategic delay/rush-for-1st
• Specific: a model of inter-jurisdictional tax-competition (P&T ch. 12)– Empirics: “Galton’s Problem”; Estimation, Inference,
Interpretation, & Presentation
Overview
• Standard Argument:– ↑ capital mobility & trade integration sharpen capital’s threat vs. domestic govts
to flee excessive/inefficient tax & public policy; forces welfare-state retrench & tax shift from more-mob. cap. (esp. finance) to less-mob. lab. (esp. skilled-man.)
• Recent counter-arguments & findings:– Some empirical Q whether constrained or ° constraint from trade/capital integ.– Counter-arguments (e.g.):
• Rodrik (Cameron): Demand (contra supply) SocPol may ↑ w/ integ indeterminate• Garrett ’98/Boix ’98: Left/active govt more/as efficient capital not flee• Hall-Soskice ‘01/Franzese-Mosher ’02: comparative institutional advantage trade-
integ foster divergence; (liquid) cap-integ may foster race to bottom (not nec’ly) zero• Swank ’02 (& many others): political & economic barriers &/or advantages
considerable maneuvering room
• Standard & all counter arguments spatial interdependence b/c whatever pressures may arise from globalization depend on what neighbors, competitors, partners, substitutes, & complements do– Accordingly, appropriate model places others’ policies on right-hand side– Basinger-Hallerberg ’04 maybe 1st in C&IPE to notice & incorporate explicitly
• Interdependence (def): yi=f(yj≠i); note: not merely that yi & yj≠i corr
A Motivating Context:Globalization & Domestic-Policy Autonomy
• Theoretical Contexts (ubiquitous):– ANY Strategic Decision-making: sisj
– Externalities & Spillovers– Learning/Emulation, Demonstration– Networks/Epistemic Communities– Literal Diffusion, Contagion, Migration
The Broad Range of Spatial Interdependence
• Tobler’s Law: ‘‘I invoke the first law of geography: everything is related to everything else, but near things are more related than distant things’’ (1970).– Plus: “Space More Than Geography” (Beck, Gleditsch, & Beardsley 2006)
• Substantive Contexts (ubiquitous):– Security Policy (e.g., alliances, wars)
– Environmental (e.g., air-pollution reg)
– Regulatory (e.g., telecomm stds)
– Legis reps’ votes depend on others’
– Elects., cand. qualities or strategies– p(∙)&outs coups (Li&Thompson 75), riots
(Govea&West 81), revolts (Brinks&Copp 06)
– Contextual effects in micro-behavior:• Braybeck&Huckfeldt 02ab, Cho 03, Huckfeldt et al.
05, Cho&Gimpel 07, Cho&Rudolph 07, Lin et al 06
• (Simmons et al.’s 06) Mechanisms:– Competition– Coercion– Learning– Emulation– [Migration/Contagion (F&H Add)]
– Policy, instit’s, regimes diffusion:• Policy: Schneider&Ingram‘88, Rose ‘93,
Meseguer ‘04,‘05, Gilardi ‘05
• Institutional or regime: Implicit/Informal: Dahl’s Polyarchy, Starr’s Democratic Dominoes, Huntington’s 3rd Wave. Explicit/Formal: O’Loughlin et al. ‘98, Brinks & Coppedge ‘06, Gleditsch & Ward ‘06, ’07
– Int’l diffusion of liberalization:• Simmons&Elkins 04, 06a, 06b, Eising 02,
Brune et al. 04, Brooks 05…
– Globalization & interdependence:• Genschel 02, Basinger&Hallerberg 04, Knill
05, Jahn 06, Swank 06, F&H 06,07, Kayser 07
Substantive & Theoretical Ubiquity & Centrality (1)
•US State Policy-innovation diffusion: deep roots & much contemporary interest, & sustained attention between:
– Crain 1966; Walker 1969, 1973; Gray 1973; Knoke 1982; Caldiera 1985; Lutz 1987; Berry & Berry 1990; Case et al. 1993; Berry 1994; Rogers 1995; Mintrom 1997ab; Brueckner 1998; Mintrom & Vergari 1998; Mossberger 1999; Berry & Berry 1999; Godwin & Schroedel 2000; Balla 2001; Mooney 2001; Wejnert 2002; Coughlin et al. 2003; Bailey & Rom 2004; Boehmke & Witmer 2004; Daley & Garand 2004; Grossback et al. 2004; Mencken 2004; Berry & Baybeck 2005; Garrett et al. 2005; Costa-Font & Ons-Novell 2006; Karch 2006; Rincke 2006; Shipan & Volden 2006; Volden 2006; Werck et al. 2006; Woods 2006; Volden et al. 2007.
•Similar policy-learning mechanisms underlie some comparative studies of policy diffusion:
– Schneider & Ingram 1988; Rose 1993; Bennett 1997; Dolowitz & Marsh 2000; True & Mintrom 2001; Tews et al. 2003; Jensen 2004; Meseguer 2004, 2005; Brooks 2005, 2007; Gilardi 2005; Gilardi et al. 2005; Murillo & Schrank 2005; Weyland 2005; Braun & Gilardi 2006; Linos 2006; Parys 2006; Ermini & Santolini 2007; Moscone et al. 2007.
•Institutional or regime diffusion likewise long-standing & recently much reinvigorated:
– Dahl’s 1971 Polyarchy (1 of 8 causes dem listed); center-stage Starr’s 1991 “Democratic Dominoes”; Huntington’s 1991 Third Wave; Beissinger 2007; Bunce & Wolchik 2006, 2007; et al. in E. Eur. Transitions; Hagopian & Mainwaring 2005 et al. in LA; O’Loughlin et al. 1998, Brinks & Coppedge 2006, Gleditsch & Ward 2006, 2007 estimated empirically extent, paths, &/or patterns dem diffuse. Kelejian et al. 2007 give institutional diffusion general theoretical & empirical treatment.
•C&IPE, e.g. globalization≈interdependence:– Diffusion of “Liberalization” & Related: Simmons & Elkins 2004, Simmons et al. 2006,
Eising 2002; Brune et al. 2004; Brooks 2005, 2007; Jordana & Levi-Faur 2005; Way 2005; Lazer 2006; Prakash & Potoski 2006; Brune & Guisinger 2007; and many others.
– Glob/Interdep/TaxComp & Dom Policy Auton: Genschel 2002; Guler et al. 2002; Franzese & Hays 2003, 2004b, 2005a, 2007abc, 2008c; Badinger et al. 2004; Basinger & Hallerberg 2004; Heichel et al. 2005; Henisz et al. 2005; Holzinger & Knill 2005; Knill 2005; Polillo & Guillén 2005; Elkins et al. 2006; Jahn 2006; Lee & Strang 2006; Manger 2006; Swank 2006; Baturo & Grey 2007; Cao 2007; Cao et al. 2007; Coughlin et al. 2007; Garretsen & Peeters 2007; Mosley & Uno 2007; Mukherjee & Singer 2007.
Substantive & Theoretical Ubiquity & Centrality (2)• Representatives’ votes (Lacombe & Shaughnessy 2005), citizens’ votes (Huckfeldt & Sprague 1991;

• Probabilities & outcomes of coups (Li & Thompson 1975), riots (Govea & West 1981), civil wars (Murdoch & Sandler 2004, Buhaug & Rød 2006) &/or revolutions (Brinks & Coppedge 2006)
• IR: interdep≈definition of subject: – States’ entry into wars, alliances, treaties (Murdoch et al. 2003), or
organizations.– Empirical attention to inherent spat-dep IR greatest in: Shin & Ward 1999;
Gleditsch & Ward 2000; Gleditsch 2002; Ward & Gleditsch 2002; Hoff & Ward 2004; Gartzke & Gleditsch 2006; Salehyan & Gleditsch
2006; Gleditsch 2007, and, in different way, Signorino 1999, 2002, 2003; Signorino & Yilmaz 2003; Signorino & Tarar 2006
• In micro-behavioral work, too, long-standing & surging interest “contextual” or “neighborhood” effects:
– Huckfeldt & Sprague 1993 review, some of which stress interdep: Straits 1990; O’Loughlin et al. 1994; Knack & Kropf 1998; Liu et al. 1998; Braybeck & Huckfeldt 2002ab; Beck et al. 2002; McClurg 2003; Huckfeldt et al. 2005; Cho & Gimpel 2007; Cho & Rudolph 2007.

– Not to mention public health and epidemiology (contagion!).• More exotic topics: ordainment of women (Chaves 1996), right-wing
extremism (Rydgren 2005), marriage (Yabiku 2006), national identity (Lin et al. 2006), & faculty (Weinstein 2007).
• i’s utility depends pi & pj b/c interdep (& vv):
• Accordingly, i’s optimal policy, pi*, depends j’s action, pj:
• So slope best-response function depends on effect of pj on marginal utility of pi:
• Therefore: Diminishing returns and…– …negative externalities =>strategic complements:
• Positive slope: positive feedback/same-signed reactions
– …positive externalities => strategic substitutes:• Negative slope: neg. feedback/opposite-signed reactions

Empirical Models of Interdependence:Galton’s Problem in C&IPE
• Interdependence yi=f(yj)• Generic (linear) dynamic spatial-lag model of C&IPE:
• Galton’s Problem: Extremely difficult disting why C(yi,yj) b/c...– 1. Correlated domestic/unit-level conditions, d (CPE)– 2. Common/corr’d exposure exog-external shocks/conditions, s (open-CPE)– 3. Responses to these 2 may be context-conditional, sd (CC-CPE)
• 40. Correlated stochastic component (Beck-Katz), nuisance C&IPE– 4. Interdependence/diffusion/contagion: yi=f(yj,CC-CPE), substance C&IPE
• Upshot Empirically (Franzese & Hays ‘03,‘04,‘06ab,‘07abcd,‘08ab):– ° omit or mis-specify CPE, tend over-estimate IPE (interdependence) & v.v.– yiyj => textbook endogeneity/simultaneity problem w/ spatial lag; analogous:
• ° fail redress endog sufficiently mis-est (usu. over-est.) ρ (under)mis-est. β– Most Important Conclusion: Model It!TM Insofar as omit or rel’ly mis-spec spatial
interdep, tend over-est impact domestic & exog-ext factors & v.v. most crucial, regardless of CPE/IPE emphasis: well-spec model & measure both.
• S-OLS may suffice. OVB >> simultaneity bias in any of practical examples we’ve considered, & S-OLS did OK our MCs provided interdep remained modest (|ρ|<.3±).

Estimating Spatial/Spatio-Temporal-Lag Models
• Inconsistent Estimators:– Omit spatial-dep (e.g., OLS): bad idea if ρ non-negligible– Ignore simultaneity (e.g., S-OLS): could be OK (in MSE)
if ρ not too large & sample-dims benevolent
• Simplest Option, if Available:– Time-Lagged Spatial-Lag OLS easy & unbiased iff…
• No contemporaneous (i.e., w/in obs period) interdependence.
• Model of temporal dynamics sufficiently accurate (see Achen)
• 1st obs pre-determined; if not, spatial-Hurwicz bias (order 1/T)
• Consistent Estimators– S-IV/2SLS/GMM: Use WX to instrument Wy, etc.– S-ML: Specify system for Max-Likelihood estimation
Estimating Spatial- & Spatio-Temporal-Dynamic Models by S-ML
• S-ML for Spatial-Lag Model:
– Std, but ε → y by |A| not 1 computational issues, plus
• Conditional S-ML S-T (ie., given 1stobs, Nx1 form); (unconditional is messy but exists; won’t show):
• Stationarity (if row-stdzd, & ρ,>0): ρ+<1• Spatial Probit: complicated but doable (show if time)• m-STAR & Est’d W; endog W: doable (show if…)

APPLICATIONS• Globalization, Tax Competition, & Domestic Policy
– Replicates: Swank&Steinmo 02, Hays 03, Basinger&Hallerberg 04• ALMP: Active-Labor-Market Policy in EU (F&H ‘06)
– DepVar: LMT spend per unemployed worker– Hypoth: Positive spillovers (@ borders) effective member-state ALMP free-
riding & underinvest. Appreciable?– IndVars: rGDPpc, UE, UDen, Deindustrialization (Iversen-Soskice), Trade,
FDI, Pop65, LCab, CDemCab, LLibVote, GCons• MIDs & Trade: Beck, Gleditsch, & Beardsley ’06
– DepVar: Directed trade data;– Hypoth: MIDs affect trade in & beyond dyad– IndVars: GDPab, POPab, Distance, tau-b, MutualDem, MID, Bi/MultiPoleSys
• AFDC & CHIPs in U.S. States (Volden ’06)– AFDC: Hypoth—“states as laboratories”≈diffusion by learning
• DepVar: max monthly AFDC benefit• Ind Vars: state’s poverty rate, avg monthly wage in retail, govt ideology (0-100, R-
L), º interparty competition (.5-1.0, comp-non), tax effort (rev as % tax capacity), & % AFDC bens paid by fed govt.
– CHIPs: Hypoth—“states as laboratories”≈diffusion by learning• DepVar: 1 if state’s CHIP includes monthly premium; IndVars same.
Practical Model Specification & Estimation• Most convenient to work in (Nx1) vector form:
• WN=an NxN of (time-invariant) spatial wts, wij, & WNIT gives W.
• E.g., 15x15 binary-contiguity from ALM paper:
– N.b., row-stdz typ., convenient, but not nec’ly subst’ly neutral
– Ideally, substance, which not nec’ly geography, in W.
• Beware of extant software: critical bug in LeSage’s MatLab code; likelihood in some third-party Stata SAR code seems flat wrong.

Notes: In the first two columns, the models are estimated assuming the spatial lags are exogenous. The model in the first column is estimated using standard ML techniques. The parentheses in this column contain estimated standard errors and the hypothesis tests assume that the asymptotic t-statistics are normally distributed. The models in columns two through four are estimated using MCMC methods with diffuse zero-mean priors. The reported coefficient estimate is the mean of the posterior density based on 10,000 observations after a 1000 observation burn-in period. The number in parentheses is the standard deviation of the posterior density. The p-values are also calculated using the posterior density. The last two models are estimated with true spatial estimators described in the text. In third column, 30 of the 10,000 spatial AR coefficients sampled from the posterior distribution were negative. In the fourth column, none of the 10,000 sampled spatial AR coefficients were negative. ***p-value <.01, **p-value<.05, *p-value <.10.
Interpreting Spatial/Spatio-Temporal Effects• The Model:
– Model may look linear, but is not; as in all beyond purely linear-additive, coefficients & effects very different things!
– Convenient, for interpretation, to write model this way too:
– Coefficients, βx are just pre-spatial, pre-temporal—and wholly unobservable!—impulse from some x to y.
• Spatio-Temporal Effects:– Post-spatial, pre-temporal “instantaneous effect” of x:
– Spatio-Temporal Response Paths:
– LR Multiplier/LR-SS:

Presenting Spatial/Spatio-Temporal Effects• Standard Errors (Confidence Intervals &
Hypothesis Tests) of Effects:
– Delta Method:
– …or Simulate!
• Upshot: Cannot see substance clearly from only the estimated coefficients & their standard errors
• Effective Presentational Options:– SR/LR-Response Grids– Spatio-Temporal Response-Paths– Maps

Conclusion• Spatial & Spatio-Temporal Interdependence
– Important & Appreciable Substance (e.g., globalization & int’l cap-tax compete seems quite real & does constrain), not Nuisance.
• Therefore: Model them. Interpret them.
• How specify & estimate models?– If space-lag is time-lagged, not problem; but if thry & substance
says immediate (w/in an observational period), can handle that too:– S-OLS not a bad strategy even then, if ρ not too big & smpl-dims
right; S-ML, & in some regards IV-based strategies, seem effective
• Spatio-Temporal Effects not directly read from coefficients: use graphs & maps & grids
• Information-demands of Galton’s Problem severe – Standard errors of effects tend big. Suspect delta-method lin-
approx. maybe part problem; plan explore performance bootstrap.– Max effort & care theory, measure, specification, to both C&IPE

• Comments:– Notice that, when we come to interpret & , we face
the same MVN integration• We haven’t seen such substantive interpretation yet attempted
fully in the literature, but we suggest an easier way to do it.
– If can order dependence pattern & ensure only antecedent y* appear on RHS, then std probit ML w/ a spatial-lag works
• We think usu. indefensible subst’ly/thry’ly, but cf. Swank on capital-tax competition, e.g., where argues US exclusively leads & omits US.
– Having y, not y*, on RHS may seem subst’ly or thry’ly desirable in some cases, but gen’ly not logically possible:
• Problem would be that outcome, yi, would indirectly (via spatial feedback) determine yi
*, but then yi* would directly determine yi.
The stochastic difference b/w them will thus a logical inconsistency.
– Notice similar MVN issue w/ time lags; suggests similar strategies (but simpler b/c ordered) may allow model temp dynamics directly rather than nuisance (e.g., BKT splines)

• Basic Idea (See Gill’s intro Bayesian textbook, e.g.):– Monte Carlo (MC): Given likelihood/posterior, can sample to
estimate any quantity of interest, including density, e.g.– Markov Chain (MC)MC:
• Each draw depends on previous, so need only conditional like./post.• Some theorems indicate, under fairly gen’l conditions, distribution
parameter draws converges to distribution under true like./post.
– Gibbs Sampler: simplest of MCMC family:• Express each parameter like./post. conditional on others.• Cycle to draw each conditional on others’ starts or previous draw• After some sufficient “burn-in”, all subsequent param-vector draws
follow true multivariate likelihood/posterior.
– Metropolis-Hastings: useful when cond’l param-dist non-std• Draws from a seed or jump distribution are accepted or rejected as
the next sampled parameters, depending on how they compare to a suitably transformed expression of the target distribution

Notes: The first two columns’ estimators assume the spatial lags exogenous. The first column gives the standard probit ML estimates. Its parentheses contain estimated standard-errors, and its hypothesis tests assume asymptotic normality of calculated t-statistics. The models in columns two through four apply MCMC methods with diffuse priors, except for a Uniform(0,1) prior on ρ. The reported coefficient estimates are posterior-density means based on 10,000 samples after 1000-sample burn-ins. Parentheses contain sample standard-deviations of these posteriors. The p-values are calculated directly from the posterior density rather than from t-statistics of assumed asymptotic-normality. The last three columns report estimates from true spatial estimators described in the text. In column three, 30 of the 10,000 sampled spatial-lag coefficients were zero; in column four, none of the 10,000 were. Column five reports estimated standard-errors and p-values based on t-statistics assumed asymptotically negative. ***, **, * indicate p-value <.01, <.05, <.10.
Notes: 1. Informative U(0,1) prior on helps. We’ve qualms.
2. Difference in Bayesian vs. frequentist significance also.
3. Note measurement/specification-error seem to have dom’d here for ML.

– Explore estimator properties systematically;
– Compare non-spatial probit & spatial-lag ML-probit & approximate specifications
•Next Crucial Extensions:– Extend to other QualDep models…
– Estimated-W models… (see next for a start)
– System-of-Equations in Space…
The m-STAR Model as an Approach to Modeled, Dynamic, Endogenous Interdependence
• Spatial Econometrics and (Political) Economy & Network Analysis and (Political) Sociology
• Co-Evolution Models in Network Analysis– (Node) Behaviors/Attributes & Network (Edges)
• Spatial-Statistical Approaches to Est’d-W
• A Simple Spatial-Econometric Proposal:– Estimated W ≈ Multiple W (m-STAR)– Endogenize W means W(y)=>S-IV in m-STAR
Spatial Econometrics
• Economists & Political Economists
• Core Question:– How alters’ actions affect
ego’s via network & v.v.?– Contagion v. Common
Exposure (Galton’s Problem)• Core Tools:
– SAR, STAR, S-QualDep…– S-GMM, S-ML
Network Analysis
• Sociologists & Political Sociologists
• Core Questions:– How do nets form?– What expl. net struct.?– How ego’s position in net
& net struct affect?• Core Tools
– Net stats (measures), graphics, ERGMs, …
• INTERDEPENDENCE– Definition: yi=f(yj≠i); i’s actions depend on j’s.– Seems subset of “Network Effects”, which also:
• Effects of structure network per se (e.g., # transitive triplets)• Effects of position i in network per se. (e.g., betweenness i)
Where Spatial Econometrics Needs to Go (& Network Analysis is or Needs to Go also)
• Two Things Always Asked Do Next– Qualitative & Limited Dependent Variables
• Bigger estimation challenges because:– Cannot place y itself on RHS, can only place y*.– N-dimensional integration to get probabilities
• Considerable progress: S-Probit/Tobit etc., S-MNP, S-…
– Estimate/Parameterize &, ideally, Endogenize W:• This essence of network analysis…• However, challenges in many contexts (e.g., C&IPE) differ:
– W not always (or usually) binary or categorical– W not always (or usually) observed.– T not always (or usually) very long.– Temporal precedence not always (or usually) suffice=>causal prec.
Leenders’ (1997) Co-evolution Model
• Selection:– Arc forms or not in continuous time Markov process:
• Contagion:– =STAR model
• => Co-Evolution Model:– Identification strategy: time lag– Findings of MC’s
• Coarse obs periodicity => big biases
• If selection & model contagion => big biases
• If contagion & model selection => biases, less big

Snijders’ (‘97-‘07) Co-evolution Model• Steglich et al. (‘07): two threefold empirical challenges
– contagion, selection, context (1st+3rd=Galton’s Problem; 2nd=coevolution => similar implications)• In gen., any omissions or inadequacies in modeling one tends against that & favor others looks most like it
– coarse periodicity, alternative mech’s & paths, net dependence precludes assume independence.• Observed Data:
– N actors connected by observed, binary, endogenous, & time-variant connectivity matrix– Vector of N observed, ordinal behaviors– Further exogenous explanators may exist at unit or dyadic level
• Model Components:– Exponential (constant hazard-rate) model of opp to act:
• One change (or not) by one person @ one time; Can parameterize the rate; Conditionally independent– When opp act, multinomial w/ N network options—change tie or none
• Compares objective with current behaves & net to current behaves & net w/ 1 switch his row: non-strategic• Can parameterize, including as function of actions; Conditionally independent
– When opp act, could instead change behavior/attribute• Compares object w/ current net & behaves to his alternative behave, w/ switch of +1,0-1 only: non-
strategic• Can parameterize, including as function network &/or of others’ actions; Conditionally independent
• Parameters to Estimate:– Coefficients of hazard-rate model and of the two multinomial logits (n.b., IIA)– Estimated by simulated method of moments; recently, by simulated likelihood
• Identification: (IIA and…)– Assume temporal precedence implies causal precedence, in particular condition on first obs– Each actor’s action or opp to act takes all else as given, i.e., conditional independence– In gen., strategy seems: control for (condition on) possible sources dependence; no stochastic dep.
Issues from C&IPE Perspective
• Many behaviors or attributes of interest as dependent variables, & relative connectivity between units less likely binary or ordinal.
• Strengths of relative connectivity not always observed, or even observable, directly.– Under these conditions, for estimation purposes, the left-hand side of the
selection component of the model would have no data. Could only estimate them off implications for behavior.
• Temporal precedence often not suffice assure causal precedence– Strategic interdep often operates literally simultaneously or even E(future)– In estimation, simultaneous generally means within an observational
period & many contexts high frequency behavior relative to obs periodicity.
– Time lagging suffices only if & insofar as spatiotemporal dynamics fully & properly specified in model (&1st non-stoch, & not w/in period “simult”).
– Condition on 1st obs needs T large for efficiency & for small-sample bias.

Co-Evolution Models in m-STAR Format
• Wr = covariates expected explain network• Co-evolution models=models with W=f(y): larger challenges.
– Our first cut: same poor man’s exogeneity, time-lag the y in W=f(y)…– Our plan: two-step estimation-procedure.
• First, apply spatial-GMM (see, e.g., Anselin 2006, Franzese & Hays 2008b) to obtain by spatial instrumentation consistent estimates of endogenous wij and their estimated variance-covariance.
• Then draw from that estimated multivariate distribution of instrumented W estimates to insert in the conditional or unconditional m-STAR likelihood.
• Maximize likelihood under each of q draws from that first-stage S-GMM instrumented estimated distribution of W estimates.
• Point estimates of parameters then just average of q 2nd stage S-ML estimates• Estimated variance-covariance of parameter-estimates is average of estimated
variance-covariance matrices from each iteration plus (1+q) times sample variance-covariance in the point estimates across iterations (King et al. 2001).
• First stage consistent, & asymptotically efficient, so estimator should inherent nice properties of S-ML and S-GMM, but no proof yet.
• Monte Carlo assessment will follow; so will direct comparison to Snijders et al. approach (near as two models can approx each other).

Conclusion• Spatial & Spatiotemporal Interdependence
– Important & Appreciable Substance (e.g., globalization & int’l cap-tax compete seems quite real & does constrain), not Nuisance.
• Therefore: Model them. Interpret them.
• How specify & estimate models?– If space-lag is time-lagged, maybe not problem; but if thry & substance says
immediate (w/in an observational period), can/should handle that too:– S-OLS not a bad strategy even then, if ρ not too big & smpl-dims right; S-ML,
&, in some regards, IV-based strategies seem effective
• Spatiotemporal Effects not directly read from coefficients: use graphs & response-plots & maps & grids
• Info-demands Galton’s Problem big, + Coevolution REALLY big– Standard errors of effects tend big. Suspect delta-method lin-approx. maybe part
problem; plan explore performance sim/boot/jack.– Max effort & care theory, measure, specification, to both C&IPE
