bargaining enforcement and multilateral sanctions when is cooperation counterproductive scholars and policymakers generally assume that multilateral cooperation is a necessary condition for economic sanctions to be of any use however previous statistical tests of this assumption have shown that sanctions are more successful with lower levels of cooperation this puzzle calls into question established theories of economic statecraft as well as theories of international cooperation in this article i test possible explanations for the ineffectiveness of multilateral cooperation on sanctions events using james fearon s 1998 breakdown of cooperation into bargaining and enforcement phases as a framework for discussion the empirical results show that when multilateral economic sanctions fail their failure is due to enforcement not bargaining problems without the support of an international organization cooperating states backslide from promises of cooperation backsliding occurs because of domestic political pressures and uncertainty about the intentions of the other sanctioning countries backsliding causes an initial burst of cooperative behavior to decay over time without institutional support cooperation is worse than useless it is counterproductive this result suggests that international cooperation is a more fragile equilibrium than previously thought but undercuts realist arguments that international organizations are unimportant

a bayesian semiparametric approach for endogeneity and heterogeneity in choice models marketing variables that are included in consumer discrete choice models are often endogenous extant treatments using likelihood based estimators impose parametric distributional assumptions such as normality on the source of endogeneity these assumptions are restrictive because misspecified distributions have an impact on parameter estimates and associated elasticities the normality assumption for endogeneity can be inconsistent with some marginal cost specifications given a price setting process although they are consistent with other specifications in this paper we propose a heterogeneous bayesian semiparametric approach for modeling choice endogeneity that offers a flexible and robust alternative to parametric methods specifically we construct centered dirichlet process mixtures cdpm to allow uncertainty over the distribution of endogeneity errors in a similar vein we also model consumer preference heterogeneity nonparametrically via a cdpm results on simulated data show that incorrect distributional assumptions can lead to poor recovery of model parameters and price elasticities whereas the proposed semiparametric model is able to robustly recover the true parameters in an efficient fashion in addition the cdpm offers the benefits of automatically inferring the number of mixture components that are appropriate for a given data set and is able to reconstruct the shape of the underlying distributions for endogeneity and heterogeneity errors we apply our approach to two scanner panel data sets model comparison statistics indicate the superiority of the semiparametric specification and the results show that parameter and elasticity estimates are sensitive to the choice of distributional forms moreover the cdpm specification yields evidence of multimodality skewness and outlying observations in these real data sets data as supplemental material are available at http dx doi org 10 1287 mnsc 2013 1811 this paper was accepted by j miguel villas boas marketing

fines leniency and rewards in antitrust this article reports results from an experiment studying how fines leniency and rewards for whistleblowers affect cartel formation and prices antitrust without leniency reduces cartel formation but increases cartel prices subjects use costly fines as punishments leniency improves antitrust by strengthening deterrence but stabilizes surviving cartels subjects appear to anticipate the lower postconviction prices after reports leniency with rewards prices fall at the competitive level overall our results suggest a strong cartel deterrence potential for well run leniency and reward schemes these findings may also be relevant for similar white collar organized crimes such as corruption and fraud

international sanctions as international punishment much of the contemporary literature on the utility of international sanctions approaches the apparent riddle of why sanctions are embraced so eagerly when they are supposedly such an ineffective tool of statecraft by focusing on the instrumental and rational purposes of sanctions as a result one purpose that does not always lend itself to a rational means end calculus the purpose of punishment tends to be overlooked or more commonly dismissed outright this article explores punishment as both a useful and an effective purpose of international sanctions it argues not only that sanctions should be distinguished from other forms of hurtful statecraft but also that they are a form of international punishment for wrongdoing despite the difficulties of applying the term punishment in the context of international relations the article then examines the purposes of punishment and reveals that only some are understandable when a model of means end rationality is used suggesting that the element of the nonrational also plays an important role in international sanctions the argument is then applied to the case of u s sanctions imposed after the soviet union s invasion of afghanistan to demonstrate the different purposes of punishment at work in this case the article concludes that just as we cannot understand punishment as a purposive human activity solely by reference to a rational model of a means to a clearly delineated end so too we cannot entirely understand sanctions as a form of international punishment by an attachment to a rational model of policy behavior however some forms of punishment are exceedingly effective and this may explain why sanctions continue to be a popular instrument of statecraft

strategic interaction and the statistical analysis of international conflict although strategic interaction is at the heart of most international relations theory it has largely been missing from much empirical analysis in the field typical applications of logit and probit to theories of international conflict generally do not capture the structure of the strategic interdependence implied by those theories i demonstrate how to derive statistical discrete choice models of international conflict that directly incorporate the theorized strategic interaction i show this for a simple crisis interaction model and then use monte carlo analysis to show that logit provides estimates with incorrect substantive interpretations as well as fitted values that can be far from the true values finally i reanalyze a well known game theoretic model of war bueno de mesquita and lalman s 1992 international interaction game my results indicate that there is at best modest empirical support for their model

on the determinants of the success of economic sanctions an empirical analysis theory theories predicting the success of economic sanctions are tested on the universe of sanction episodes from 1914 to 1989 hypotheses the probability of success depends upon the cost to the target nation the extent of trade linkages between target and sender the stability of the target the amount of time sanctions are in force and whether financial sanctions are utilized method data are analyzed using logistic regression results the factors affecting success depend upon the goals of the sending nations when that goal is simply destabilization the principal determinant of success is the initial stability of the target for other goals the use of financial sanctions is most effective we also find evidence of a modest downward trend over time in the relative effectiveness of sanctions in the latter category

coordination in the presence of asset markets markets aggregate widely dispersed information and direct resources to where they produce the greatest value friedrich a hayek 1945 adam smith 1776 these dual roles of informational and allocative efficiency help explain why asset markets are often used to guide economic activity such as production and investment many economic contexts involving production and investment are characterized by multiple equilibria john bryant 1983 jack hirshleifer 1983 russell w cooper 1999 colin camerer and marc knez 1997 jordi brandts and david j cooper 2006 when asset markets are linked to such contexts it is important to understand what role they play in aiding coordination and selecting equilibria if asset markets obtain both informational and allocative efficiency in a multiple equilibrium con text then they should coordinate the beliefs of economic agents and guide behavior to an efficient equilibrium indeed some evidence suggests that one sided auction markets may facilitate efficient coordination in an environment with multiple equi libria john b van huyck raymond c battalio and richard o beil 1993 vincent crawford and bruno broseta 1998 however the broader question of whether asset markets generally lead to efficient coordination in environments with multiple equi libria remains an open question in this paper we explore experimentally the influence of two sided futures asset markets on behavior and outcomes in an economic activity characterized by multi plicity of equilibria we use laboratory experiments where we can control impor tant features of both the market and the underlying activity and focus on situations where the outcome of the economic activity is sensitive to the behavior of small numbers of agents the economic activity in our setting consists of a coordination game with pareto ranked equilibria in which the payoff to each player is a function of her own choice or input and group output which is some order statistic such as the minimum of all players input choices see van huyck battalio and beil 1990 van huyck battalio and beil 1991 crawford 1995 players all do better if they coordinate on the highest output efficient equilibrium which is pareto optimal but they also prefer to select a lower input if they believe others will do so coordination games of this kind have been applied widely to model economic activity from the relationship between beliefs and output in macroeconomic models cooper 1999 to public good provision hirshleifer 1983 to firm production

naked exclusion an experimental study of contracts with externalities this paper reports the results of an experiment designed to assess the ability of an incumbent seller to profitably foreclose a market with exclusive contracts we use the strategic environment described by rasmusen ramseyer and wiley 1991 and segal and whinston 2000 where entry is unprofitable when sufficiently many downstream buyers sign exclusive contracts with the incumbent when discrimination is impossible the game resembles a stag hunt coordination game in which the buyers payoffs are endogenously chosen by the incumbent seller exclusion occurs when the buyers fail to coordinate on their preferred equilibrium two way non binding pre play communication among the buyers lowers the power of exclusive contracts and induces more generous contract terms from the seller when discrimination and communication are possible the exclusion rate rises divide and conquer strategies are observed more frequently when buyers can communicate with each other exclusion rates are significantly higher when the buyers payoffs are endogenously chosen rather than exogenously given finally secret offers are shown to decrease the incumbent s power to profitably exclude

theocracy and resilience against economic sanctions abstract this paper provides a simply theory to explain the impact of sanctions on a regime s policies and behavior sanctions are generally put to strip the target country from its available rents and weaken the government s stance against growing discontent in the population we show however that sanctions may give legitimacy to an incumbent government by influencing the optimal level of religious ideology provided by the state and further stabilizing its grip to power and rents while in a good state of nature sanctions build resilience as long as religious ideology among the population is strong at bad times they compel the target country to move towards ideological moderation in a world of asymmetric information the target country always finds it optimal to send a signal that truly represents the prevailing state of nature in order to induce learning and reach a win win outcome

domestic opposition and signaling in international crises this article explores the effect of domestic political competition on the escalation of international crises it combines an incomplete information model of crisis bargaining with a simple model of two party electoral choice one state has two strategic actors a government and an opposition party both of which declare openly whether they support the use of force to alter the status quo the rival state updates its beliefs and selects its strategy in response to both signals the parties payoffs depend upon a retrospective evaluation by the domestic electorate the model shows that the inclusion of a strategic opposition party decreases the ex ante probability of war by helping to reveal information about the state s preferences this finding has important implications for research on democracy and international conflict since it suggests a mechanism through which democratic states can overcome informational asymmetries which have been identified as a central obstacle to negotiation

structural analysis of manufacturer pricing in the presence of a strategic retailer consumer goods manufacturers usually sell their brands to consumers through common independent retailers theoretical research on such channel structures has analyzed the optimal behavior of channel members under alternative assumptions of manufacturer retailer interaction vertical strategic interaction research in empirical industrial organization has focused on analyzing the competitive interactions between manufacturers horizontal strategic interaction decision support systems have made various assumptions about retailer pricing rules e g constant markup category profit maximization the appropriateness of such assumptions about strategic behavior for any specific market however is an empirical question this paper therefore empirically infers 1 the vertical strategic interaction vsi between manufacturers and retailer 2 the horizontal strategic interaction hsi between manufacturers simultaneously with the vsi and 3 the pricing rule used by a retailer the approach is particularly appealing because it can be used with widely available scanner data where there is no information on wholesale prices researchers usually have no access to wholesale prices even manufacturers who have access to their own wholesale prices usually have limited information on competitors wholesale prices in the absence of wholesale prices we derive formulae for wholesale prices using game theoretic solution techniques under the specific assumptions of vertical and horizontal strategic interaction and retailer pricing rules we then embed the formulae for wholesale prices into the estimation equations while our empirical illustration is using scanner data without wholesale prices the model itself can be applied when wholesale prices are available early research on the inference of hsi among manufacturers in setting wholesale prices using scanner data e g kadiyali et al 1996 1999 made the simplifying assumption that retailers charge a constant margin this assumption enabled them to infer wholesale prices and analyze competitive interactions between manufacturers in this paper we show that this model is econometrically identical to a model that measures retail price coordination across brands hence the inferred cooperation among manufacturers could be exaggerated by the coordinated pricing category management done by the retailer we find empirical support for this argument this highlights the need to properly model and infer vsi simultaneously to accurately estimate the hsi when using data at the retail level functional forms of demand have been evaluated in terms of the fit of the model to sales data but recent theoretical research on channels lee and staelin 1997 tyagi 1999 has shown that the functional form has serious implications for strategic behavior such as retail passthrough while the logit and linear model implies equilibrium passthrough of less than 100 lee and staelin call this vertical strategic substitute vss the multiplicative model implies optimal passthrough of greater than 100 vertical strategic complement vsc because passthrough rates on promotions have been found to be below or above 100 chevalier and curhan 1976 armstrong 1991 we empirically test the appropriateness of the logit vss and the multiplicative vsc functional form for the data we perform our analysis in the yogurt and peanut butter categories for the two biggest stores in a local market we found that the vss implications of the logit fit the data better than the multiplicative model we also find that for both categories the best fitting model is one in which 1 the retailer maximizes category profits 2 the vsi is manufacturer stackelberg and 3 manufacturer pricing hsi is tacitly collusive the fact that the retailer maximizes category profits is consistent with theoretical expectations the inference that the vsi is manufacturer stackelberg reflects the institutional reality of the timing of the game retailers set their retail prices after manufacturers set their wholesale prices note that in the stores and product categories that we analyze the two manufacturers own the dominant brands with combined market shares of about 82 in the yogurt market and 65 in the peanut butter market the result is also consistent with a balance of power argument in the literature the finding that manufacturer pricing is tacitly collusive is consistent with the argument that firms involved in long term competition in concentrated markets can achieve tacit collusion managers use decision support systems for promotion planning that routinely make assumptions about vsi hsi and the functional form the results from our analysis are of substantive import in judging the appropriateness of assumptions made in such decision support systems

does high income promote democracy the authors construct a statistical model with which to test whether the regularity that democracy is more commonly found among wealthy countries stems from a democratizing effect of high income or is due entirely to other factors such as the historical context various features of the institutional setting and simultaneity with the process of leadership change even after correcting for these many other influences the democratizing effect of income remains as a statistically significant factor promoting the emergence of democratic political institutions the authors go on to find that leaders risks of losing power rise during their time in office and that these risks are higher in more democratic countries the authors confirm the finding by burkhart and lewis beck that the democracy promoting effect of income is stronger among the european countries they suggest that high income has a more powerful democratizing effect among the southern european countries because it interacts with pressure from major trading partners to democratize this suggests a revaluation of policies designed to foster the replacement of authoritarian regimes by democratic ones through free trade

the political effectiveness of terrorism revisited terrorists attack civilians to coerce their governments into making political concessions does this strategy work to empirically assess the effectiveness of terrorism the author exploits variation in the target selection of 125 violent substate campaigns the results show that terrorist campaigns against civilian targets are significantly less effective than guerrilla campaigns against military targets at inducing government concessions the negative political effect of terrorism is evident across logit model specifications after carefully controlling for tactical confounds drawing on political psychology the author concludes with a theory to account for why governments resist compliance when their civilians are targeted

economic interdependence bargaining power and political influence bargaining theory is used to evaluate the proposition that asymmetrical economic interdependence among states is a source of political power it is shown that asymmetrical economic interdependence does not imply that less dependent actors will be able to exercise political influence over more dependent ones the use of economic interdependence for political influence requires instead that the exchange of economic resources for political concessions make both parties to a relationship better off than they would be if they bargained over the distribution of the gains from the economic relationship alone whether this is true is independent of the degree of asymmetry in the economic relationship or its direction an explanation is given for the fact that other scholars have reached different conclusions and the implications of these results for our understanding of a variety of types of relations among governments are derived

precision guided or blunt the effects of us economic sanctions on human rights this study analyzes the consequences of economic sanctions for the target country s human rights situation we offer a political economy explanation for different types of human rights infringements or improvements in reaction to economic shocks caused by sanctions based on that explanation we derive hypotheses linking sanctions to four types of human rights economic rights political and civil rights basic human rights and emancipatory rights we use endogenous treatment regression models to test those hypotheses by estimating the causal average treatment effect of us economic sanctions on each type of human rights within a uniform empirical framework unlike previous studies we find no support for adverse effects of sanctions on economic rights or basic human rights once the endogenous selection of sanctioned countries is modelled with respect to women s rights our findings even indicate a positive effect of sanctions that is associated with improvements in women s economic rights only our results for political rights and civil liberties suggest significant deterioration under economic sanctions we conclude that it is important to account for the potential endogeneity of economic sanctions and to distinguish different dimensions of human rights as the effects of economic sanctions along those dimensions may vary considerably

institutions and behavior experimental evidence on the effects of democracy a novel experiment is used to show that the effect of a policy on the level of cooperation is greater when it is chosen democratically by the subjects than when it is exogenously imposed in contrast to the previous literature our experimental design allows us to control for selection effects e g those who choose the policy may be affected differently by it our finding implies that democratic institutions may affect behavior directly in addition to having effects through the choice of policies our findings have implications for the generalizability of the results of randomized policy interventions

a computable general equilibrium model of international sanctions in iran we detail recent international sanctions against the iranian economy and its government imposed by a subset of developed countries the effects of these sanctions on the iranian economy in general and upon upper and lower income rural and urban iranian households as well as the iranian government are modelled using a computable general equilibrium cge model we supplement the global trade analysis project 8 data set using income and expenditure shares from the urban and rural household income and expenditure survey from the statistical centre of iran sci the model is calibrated to simulate the effects of international sanctions as closely as possible we use endogenous trade taxes to simulate the effects of sanctions on iranian oil and petrochemical exports and iranian imports of petroleum products metal products and motor vehicles our study finds that international sanctions reduced aggregate iranian welfare by 14 15 rural households in iran suffered welfare losses which were almost double those experienced by urban households and the poorest urban and rural households experienced the largest welfare losses in the order of 5 10 but the government of iran sees a decrease in real revenue of 40 50 due to the large negative effect of sanctions on the iranian oil sector

endogenous incentive contracts and efficient coordination we examine the effects of endogenous assignment to incentive contracts on worker productivity assignment to high performance pay via a market mechanism is roughly twice as effective as imposing the same contract exogenously this positive effect is largely offset by a negative effect for workers that endogenously choose low performance pay we decompose the positive effect of endogenous assignment to high performance pay into effects due to selection and strategic anticipation and find that selection has a greater effect than strategic anticipation we use a reverse sort treatment to show that the effect of selection is sufficiently strong to overcome the direct effect of lower performance pay yielding coordination at high effort levels in spite of low incentives

a control function approach to endogeneity in consumer choice models abstract endogeneity arises for numerous reasons in models of consumer choice it leads to inconsistency with standard estimation methods that maintain independence between the model s error and the included variables the authors describe a control function approach for handling endogeneity in choice models observed variables and economic theory are used to derive controls for the dependence between the endogenous variable and the demand error the theory points to the relationships that contain information on the unobserved demand factor such as the pricing equation and the advertising equation the authors approach is an alternative to berry levinsohn and pakes s 1995 product market controls for unobserved quality the authors apply both methods to examine households choices among television options including basic and premium cable packages in which unobserved attributes such as quality of programming are expected to be correlated with price without correcting for endogeneity aggregate d

do economic sanctions destabilize country leaders do economic sanctions destabilize the governments they target a form of foreign pressure sanctions are typically meant to alter the policies of other countries there is much pessimism on whether they ever work this article shows that economic pressure works in at least one respect it destabilizes the leaders it targets i present a theoretical argument that explains why destabilization is a necessary condition for successful coercion i find evidence that pressure destabilizes in a large panel of cross country time series data the destabilization finding indicates that sanctions may be more effective at altering policies than we think i conclude by noting that greater optimism regarding the effectiveness of sanctions should be balanced by a careful consideration of the policy s real and sizeable costs for those caught in the middle

auctions as coordination devices this paper develops an economic argument relating auctions to high market prices at the core of the argument is the claim that market competition and bidding in an auction should be analyzed as part of one game where the pricing strategies in the market subgame depend on the bidding strategies during the auction i show that when there are two licenses for sale the only equilibrium in the overall game that is consistent with the logic of forward induction is the one where firms bid an amount almost equal to the profits of the cooperative market outcome and follow a cooperative pricing strategy in the market game resulting in high prices with three or more licenses the auction format co determines whether or not the forward induction argument works

what price coordination the efficiency enhancing effect of auctioning the right to play a model is proposed to explain the results of recent experiments in which subjects repeatedly played a coordination game with the right to play auctioned each period in a larger group subjects bid the market clearing price to a level recoverable only in the efficient equilibrium and then converged to that equilibrium although subjects playing the game without auctions converged to inefficient equilibria the efficiency enhancing effect of auctions is reminiscent of forward induction but is not explained by equilibrium refinements the model explains it by showing how strategic uncertainty interacts with history dependent learning dynamics to determine equilibrium selection copyright 1998 by american economic association

the termination of international sanctions explaining target compliance and sender capitulation abstract with the proliferation of sanctions after the end of the cold war the termination of these punitive measures has become a ubiquitous phenomenon in international politics yet research has hitherto almost exclusively focused on sanctions implementation and effectiveness whereas their termination has received little attention in this paper we draw on studies analyzing the varying duration of sanctions to examine under which conditions they end in contrast to prior research that has mostly treated the end of sanctions as a single category our analysis disaggregates sanctions termination by target compliance and sender capitulation we run a competing risks model using novel dyadic sanctions data and show that the determinants of both outcomes significantly diverge while poor economic health and high political volatility in the target country make it significantly more likely to comply political alignment between the sender and target and leadership changes in the sender country lead to a higher probability of sender capitulation
