Do research joint ventures serve a collusive function?

Every year thousands of firms are engaged in research joint ventures (RJV), where all knowledge gained through R&D is shared among members. Most of the empirical literature assumes members are non-cooperative in the product market. But many RJV members are rivals leaving open the possibility that firms may form RJVs to facilitate collusion. We examine this by exploiting variation...

Redistributive preferences, redistribution, and inequality: Evidence from a panel of OECD countries

This paper describes individuals' inequality perceptions, distributional norms, and redistributive preferences in a panel of OECD countries, primarily focusing on the association between these subjective measures and the effective level of inequality and redistribution. Not surprisingly, the effective level of redistribution (after tax-and-transfer inequality) is positively (...

Improving efficiency through consolidation of jurisdictions? Evidence from the cantons of Switzerland

The purpose of this paper is to analyze the optimal scale of local jurisdictions (cantons) in Switzerland applying Data Envelopment Analysis (DEA) to the years 2000 to 2004. Aggregate output performance indicators for four local government activities (administration, education, health, and transportation) are used to measure technical and scale efficiency and to derive DEA scores....

Race, Social Class, and Bulimia Nervosa

In this paper we explore a serious eating disorder, bulimia nervosa (BN), which a­fflicts a surprising number of girls in the US. We challenge the long-held belief that BN primarily affects high income White teenagers, using a unique data set on adolescent females evaluated regarding their tendencies towards bulimic behaviors independent of any diagnoses or treatment they have...

Marijuana on Main Street: What if?

Illicit drug use is prevalent around the world. While the nature of the market makes it difficult to determine the total sales worldwide with certainty, estimates suggest sales are around 150 billion dollar a year in the United States alone. Among illicit drugs marijuana is the most commonly used, where the US government spends upwards of $7.7 billion per year in enforcement of the...

Will you still want me tomorrow? The dynamics of families' long-term care arrangements

We estimate dynamic models of elder-care arrangements using data from the Assets and Health Dynamics Among the Oldest Old Survey. We model the use of institutional care, formal home health care, care provided by a child, and care provided by a spouse in the selection of each care arrangement, the primary arrangement, and hours in each arrangement. Our results indicate that both...

Default times, no-arbitrage conditions and changes of probability measures

In this paper, we give a financial justification, based on no-arbitrage conditions, of the (H)-hypothesis in default time modeling. We also show how the (H)-hypothesis is affected by an equivalent change of probability measure. The main technique used here is the theory of progressive enlargements of filtrations.

Seeds of Distrust: Conflict in Uganda

We study the effect of civil conflict on social capital, focusing on the experience of Ugandaduring the last decade. Using individual and county-level data, we document large causal effects on trust and ethnic identity of an exogenous outburst of ethnic conflicts in 2002-05. We exploit two waves of survey data from Afrobarometer 2000 and 2008, including information on socioeconomic...

Gender differences in competitiveness and risk taking: comparing children in Colombia and Sweden

We explore gender differences in preferences for competition and risk among children aged 9-12 in Colombia and Sweden, two countries differing in gender equality according to macro indices. We include four types of tasks that vary in gender stereotyping when looking at competitiveness: running, skipping rope, math and word search. We find that boys and girls are equally competitive...

Identification and estimation of thresholds in the fixed effects ordered logit mode

The paper proposes a new estimator for the fixed effects ordered logit model. In contrast to existing methods, the new procedure allows estimating the thresholds. The empirical relevance and simplicity of implementation is illustrated in an application to the effect of unemployment on life satisfaction.

Trade and growth in an unequal global economy

This paper studies the patterns of trade and the incentives to innovate in an unequal global economy. We introduce non-homothetic preferences in a general-equilibrium model of endogenous growth and international trade between two countries, and argue that the effects of market integration on the consequent trade patterns and the incentives to innovate depend on the degree of income...

Time consistent optimal fiscal policy over the business cycle

This paper examines a dynamic stochastic economy with a benevolent government that cannot commit to future policies. Following Phelan and Stacchetti (2001), we consider sequential sustainable equilibria (SSE). We numerically solve for the set of equilibrium payoffs, and investigate whether the time consistency problem of capital income tax is quantitatively important. For a...

Is Socially Responsible Investing Really Beneficial? New Empirical Evidence for the US and European Stock Markets

This paper empirically examines the theoretically ambivalent relationship between socially responsible investing (SRI) and stock performance. It extends the existing literature by considering both the US and the entire European stock markets as well as by using consistent world-wide corporate sustainability performance data. Our portfolio analysis from 1998 to 2009 reveals the appeal...

Does raising the retirement age increase employment of older workers?

Two pension reforms in Austria increased the early retirement age from 60 to 62 for men and from 55 to 58.25 for women. The reforms reduced early retirement by 18.9 percentage points among affected men aged 60-62 and by 22.3 percentage points among affected women aged 55-58.25. The associated increase in employment was merely 6.8 percentage points among men and 10.1 percentage points...

Inefficient markets

Traders' values and information typically consist of both private and common-value elements. In such environments, full allocative efficiency is impossible when the private rate of information substitution differs from the social rate (Jehiel and Moldovanu, 2001). We link this impossibility result to a failure of the efficient market hypothesis, which states that prices...

Expectations as reference points: field evidence from experienced subjects in a competitive, high-stakes environment

We show that professional soccer players exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that a player breaches the rules of the game, measured by the referee’s assignment of cards, with a significantly higher probability if his team is behind the expected match outcome,...

Communication and Competition

Charness and Dufwenberg (American Economic Review, June 2011, 1211-1237) have recently demonstrated that cheap-talk communication raises efficiency in bilateral contracting situations with adverse selection. We replicate their finding and check its robustness by introducing competition between agents. We find that communication and competition act as "substitutes:"...
