On representative social capital

This paper analyzes the behavior of subjects randomly drawn from the Dutch population who reveal their capacity to provide and sustain social capital by their propensity to invest and reward investments in an economic experiment. We find that heterogeneity in behavior is characterized by several asymmetries—men, the young and elderly, and low educated individuals invest relatively less, but reward significantly more investments. The age effects are found to corroborate existing findings, whereas those of gender and education do not. Higher expected levels of investments by others are found to have a positive and significant effect on own investments. Finally, a laboratory experiment with student subjects is found to provide a lower bound of the population level of social capital.     

A different look at Lenin’s legacy: Social capital and risk taking in the Two Germanies

What are the long-term effects of Communism on economically relevant notions such as social trust, fairness, and scope of cooperation? To answer this question, we study the post-unification trajectory of convergence between East and West German individuals with regard to trust, cooperation, and risk. Our hypotheses are derived from a model of German unification that incorporates individual responses both to incentives and to values inherited from earlier generations as recently suggested in the literature. Using two waves of balanced panel data, we find that despite twenty years of unification East Germans are still characterized by a persistent level of social distrust. In comparison to West Germans, they are less inclined to see others as cooperative. East Germans are also found to have been more risk loving than West Germans. However, risk attitudes fully converged recently.     

Social interaction and economic organization: Toward an integrative microeconomic model

In the context of increasingly complex economies, with information more and more complicated to handle, social interaction may allow spontaneous co-operation and be more efficient than market or state regulations to overcome co-ordination and information problems. This article provides a theoretical model that compares three “pure forms” of economic organization: state-controlled production, unregulated market, and voluntary organization. We model the behavior of agents who are embedded in a social structure that is characterized by three parameters: the intensity of socialization, the size of individual social space, and the overall level of trust in society. We then study how social interaction parameters influence the relative efficiency of the three different forms of organization.     

“The mother of all political problems”? On asylum seekers and elections

As immigration to Europe has increased, so has support for extremist parties. While many studies have examined the effect of immigration on election outcomes, few have probed the effect of asylum seekers – those fleeing strife and persecution – on voting, nor has there been much research on the mediating role of local economic conditions. Drawing on county level panel data from Germany, our study fills both gaps. We find that economic circumstances, as measured by the unemployment rate and the level of disposable income, condition voters’ responses to the presence of asylum seekers, but the effects for parties on the far right and left diverge markedly. Under economic prosperity, immigration increases support on both sides of the political spectrum. As economic conditions worsen, however, the effect of asylum seekers on the vote share for the far right remains stable, but weakens for the left, eventually becoming negative. This divergence – which has not yet been reported in the literature – suggests that an influx of asylum seekers, particularly when coupled with an economic downturn, could tilt a political system rightwards. From a policy perspective, these results suggest that heterogeneity arising from local economic conditions has important implications for the regional allocation of asylum seekers.     

Reputation, group structure and social tensions

Social tensions impede social cohesion and public goods provision, and can be a driving force for more serious conflicts such as civil wars. Surprisingly, the emergence of social tensions has been studied only rarely in the literature. In the present contribution a game-theoretic model highlights how reputation concerns and the structure of group cleavages matter for the emergence of social tensions. In particular, the respective effects of ethnic fractionalization, polarization and segregation are analyzed. The differences between ethnicity and class, and the role of social mobility are also studied. The predictions of the model can account for recent empirical evidence.     

Does trust promote growth?

We examine the effect of generalized trust on long-term economic growth. Unlike in previous studies, we use Bayesian model averaging to deal rigorously with model uncertainty and attendant omitted variable bias. In addition, we address endogeneity and assess whether the effect of trust on growth is causal. Examining more than forty regressors for nearly fifty countries, we show that trust exerts a positive effect on long-term growth and, based on the posterior inclusion probabilities, suggest that trust is an important driver of long-term growth. Our results also show that trust is key for growth in countries with a weak rule of law.     

On the distribution of education and democracy

This paper empirically analyzes the influence of education on democracy by controlling for unobservable heterogeneity and by taking into account the persistency of some of the variables. The most novel finding is that an increase in the education attained by the majority of the population is what matters for the implementation and sustainability of democracy, rather than the average years of schooling. We show this result is robust to issues pertaining omitted variables, outliers, sample selection, or a narrow definition of the variables used to measure democracy.     

Inheritance patterns in migration-prone communities of the Peruvian Highlands

On the basis of detailed information on inheritance practices collected in the course of an in-depth survey of three Andean communities of Peru, and unlike most empirical studies which rely on remittance functions, we have been able to estimate an inheritance function with a view to identifying the main factors associated with particular patterns of land bequests. A central result is that the positive relationship between caring and a favourable access to land bequest indeed exists, yet is only observed for migrant children (whether urban or rural, long-distance or short-distance migrants). Combined with other findings and observations, this result strengthens the case for an interpretation based on an active role of potential heirs in the determination of inheritance outcomes. It therefore calls into question the strategic bequest theory which presumes that parents are the ultimate decision-makers in this matter. In addition, our study shows that inheritance patterns are complex: besides migration and caring behavior, personal characteristics of potential heirs, such as gender, birth order, and family status (having children or not), do appear to influence division of parental land.     

Informal insurance in social networks

This paper studies bilateral insurance schemes across networks of individuals. While transfers are based on social norms, individuals must have the incentive to comply. We investigate the structure of self-enforcing insurance networks. Network links play two distinct and possibly conflictual roles. They act as conduits for both transfers and information; affecting the scope for insurance and the severity of punishments upon noncompliance. Their interaction leads to a characterization of stable networks as suitably “sparse” networks. Thickly and thinly connected networks tend to be stable, whereas intermediate degrees of connectedness jeopardize stability. Finally, we discuss the effect of discounting on stability.     

Collective management of residential housing in Russia: The importance of being social

Homeowners associations (HOAs) implement collective management in residential housing. We assess the performance of such associations in Russia by using the stochastic frontier technique. Cultural traits enabling tenants to make proper use of the HOA decision-making procedures are essential for resolving the collective action problem and ensure accountability of governing bodies and outside contractors. Such “technical civic competence” has a stronger impact on HOA performance than more conventional forms of social capital which rise in their significance when HOA governance breaks down and informal grassroots alternatives are mobilized instead. Massive and indiscriminate “supply-led” introduction of collective management in residential housing without matching cultural and institutional prerequisites could be counterproductive. Flexibility, freedom of choice, and market development are required to avert the failures of HOAs commonly observed in Russia.     

Group insurance and lending with endogenous social collateral

We construct a dynamic model of self-enforcing insurance provision and lending to a community of borrowers who are connected by risk-sharing arrangements that are themselves subject to enforcement problems, as in Kocherlakota (1996). We show that an outside lender offering constant-consumption contracts can earn a higher profit if he conditions his repeated interactions with each borrower on the history of his interactions with all the group members (a joint liability contract), rather than on his history with that borrower only (individual liability contracts). This result holds even in the absence of informational asymmetries. The observation driving it is that with individual liability contracts, a joint welfare-maximizing group may prefer to have one or more group members default on their contracts, so that the group can consume a mix of outside funds and the defaulters' stochastic income. One contribution of our work is to give precise economic content to the concept of “social collateral” as the per-agent surplus from group risk-sharing over autarky. The group can deter its members from defaulting on their contracts with the principal by threatening to reduce that surplus.     

DEVELOPING COUNTRY BORROWING FROM A MONOPOLISTIC LENDER: STRATEGIC INTERACTIONS AND ENDOGENOUS LEADERSHIP*

We develop a two‐period model with endogenous investment and credit flows. Credit is subject to quantitative restrictions. With an exogenous restriction, we analyse the welfare effects of a temporary consumption tax. We then consider three scenarios under which a monopoly lender optimally decides the level of credit and a borrower country chooses a consumption tax: one in which the two parties act simultaneously and two scenarios where one of them is a Stackleberg leader. The equilibrium under the leadership of the borrower country is Pareto superior to the simultaneous move equilibrium but may or may not be to that under the leadership of the lender. If the sequence of moves is itself chosen strategically, leadership by the borrower emerges as the unique equilibrium.     

Neckties in the tropics: a model of international trade and cultural diversity

Abstract .  Some cultural goods are consumed socially and are characterized by the same consumption network externalities as languages. Also, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in all countries. For such goods, costless trade and communication tend to lead to the dominance of one cultural style, increasing utility in the short run but reducing quality and welfare in the long run. Increasing protection while keeping communication costs low may stimulate production of cultural goods that are 'compatible' with the dominant style, adding little to the stock of usable ideas.     

Social capital and political institutions: Evidence that democracy fosters trust

This paper finds evidence that more democratic political institutions increase trust. Second generation immigrants with ancestries from 115 countries are studied within 30 European countries. Comparing individuals born and residing in the same country, those whose father was born in a more democratic country express higher trust than those whose father was born in a less democratic country. The results are robust to individual, parental, and ancestral country controls.     

Variety‐Controlling Public Policy Under Addiction and Saturation

This paper constructs a tractable general equilibrium model for investigating the dissimilar effects of addiction and saturation on consumption and public policy. By introducing an industry‐specific intertemporal consumption externality, we provide clear analytical results that a lump‐sum subsidy for firms can increase welfare in the presence of a negative externality (saturation). A tax can accomplish the same given a positive externality (addiction). Unlike existing studies of cultural goods, these results are not based on assumptions concerning exogenous different preferences across groups, but rather on conventional monopolistic competition and consumption habit formation models in macroeconomics.     

Political origins of financial structure

There is growing policy interest in the role of financial structure in promoting development. However, very little is known about how different financial structures emerge and evolve. In this paper we empirically assess the political origins of financial structure. Using difference–in difference estimation and annual data, we study the effects of democratization on financial structure in a sample of 96 countries covering the period 1970–2005. Democratization here corresponds to the event of becoming a democracy. We find that democratization leads to a more market-based financial system. Democratic change could also be incremental rather than a one off. To identify the effect of incremental democratic change on financial structure we estimate a separate model and find that democracy matters. We also find that countries with substantial democratic capital are more likely to have a market-based financial structure. Our main results are robust to a variety of controls, Arellano–Bond GMM estimation, alternative measures of democracy and financial structure, and across different samples.     

Evolutionary stability of social norms in a socioeconomic equilibrium model

A hybrid of a model of economic equilibrium in two markets and a social game is formed. The link between the two is established through a social norm that conditions correct social behavior on economic variables and therefore distorts the economic equilibrium allocation. The initial endowment of an individual determines whether she gains from a social norm. The evolution of norms is examined in a dynamic model where norms are more likely to persist if they deliver higher utility to their believers. Also it is assumed that norms lose importance when they are disobeyed by their believers. Optimally coordinating norms are not necessarily evolutionarily stable, and a suboptimal norm can be the outcome of the evolutionary process.
