No country for young men: International migration and left‐behind children in Tajikistan

This paper investigates the effects of international migration on the schooling and labour outcomes of left‐behind children in rural Tajikistan. Using three‐wave panel survey data, I rely on an instrumental variable strategy to address the non‐random selection into migration. I identify important and gender‐differenced schooling and labour supply responses. My findings suggest that boys living in migrant households are less likely to lag behind at school or work. At the intensive margin, they also report fewer hours of work per week. On the other hand, left‐behind teenage females undertake a higher number of domestic chores. They appear to marry earlier as well. The migration impact on boys appears to be driven by remittances and the improved financial situation of households. The absence of any positive influence on the education of left‐behind girls is likely to be explained by Tajikistan's cultural norms and institutions.     

THE RELATIONSHIP BETWEEN RELATIVE RISK AVERSION AND THE LEVEL OF EDUCATION: A SURVEY AND IMPLICATIONS FOR THE DEMAND FOR LIFE INSURANCE

The expected utility hypothesis has been widely used in the construction of economic models and numerous difficulties are encountered in attempting to take into account preferences toward risk in a real‐world setting. More recently, attention has focused on comparative studies in economics and business in an international framework and problems related to the hypothesis of relative risk aversion (RRA). One ambiguous hypothesis is the relationship between the level of RRA and the level of education, which has been found either positive or negative. From a causality point of view, it may be argued that investors with a high level of education are less risk averse, but it may also be argued that less risk‐averse individuals choose to pursue a higher level of education. The purpose of this paper is to survey the empirical literature on this subject. It provides evidence that risk aversion is negatively correlated with higher education and human development. The results have important implications for macroeconomic empirical studies and the demand for financial assets and more specifically on the demand for life insurance. Assuming the same degree of RRA for utility‐maximizing consumers should be limited to homogeneous samples.     

Bankruptcy Litigation and Relationship Banking

This paper analyzes how bankruptcy litigation affects the value of relationship banking. In our model, bankruptcy courts may make type 1 errors, i.e., they may declare that an insolvent firm is solvent; and they may make type 2 errors, i.e., they may declare that a solvent firm is insolvent. Our model provides four results. First, the cost of bank debt decreases when the probability that bankruptcy courts make type 2 errors increases. Second, the value of relationship banking increases when the probability that bankruptcy courts make type 1 errors increases. Third, the cost of credit intermediation decreases when the probability that bankruptcy courts make type 2 errors increases. Fourth, the diversification mechanism does not fully solve the delegated monitoring problem.     

Asymmetric information,imitative behaviour and communication: price formation in an experimental asset market

The paper describes experimental results from a simulated stock market with manipulation of asymmetric information and communication, including conditions intended to promote imitative behaviour and rumour. Price discovery was inefficient when the presence of insiders was disguised, compared to a homogeneous expectations baseline. When the presence of insiders was revealed observed prices became efficient with respect to bad news but not with respect to good news, possibly suggesting loss-averse behaviour. With free communication there was a decrease in both efficiency and price volatility—insider information was masked by noise. Price formation under these conditions was similar to baseline, but with weak evidence of speculative pricing. It is conjectured that other factors than informational noise may be necessary determinants of herd behaviour, but further work is indicated.     

Walras's tâtonnement : a reply to Rebeyrol and Costa

Abstract

About 50 years ago a lively discussion was started in the ‘Notes and Memoranda’ sections of the Economic Journal about the new welfare economics that had been initiated by Kaldor and Hicks 10 years earlier and was heavily criticized by Little in 1950. Altogether 18 Notes appeared dealing with questions of definition, of limitations, of practical relevance and theoretical details. This paper gives an overview of this discussion and presents it as a methodological approach of the past which that declined as a consequence of the spread of the referee process.     

Informational efficiency in the Tokyo Stock Exchange, 1931–40

This article relies on a unique dataset of daily price indices for stocks and bonds to analyse the functioning of the Tokyo Stock Exchange (TSE) in the period 1931–40. We find that this market deviated from weak‐form efficiency, in a context of cross‐market segmentation, short‐run spillovers, and turmoil surrounding major events. In this context, zaibatsu insiders were able to make abnormal returns via informed trading, while other uninformed investors could rely on technical rules to make abnormal profits. Such findings call for a micro‐level analysis of the interwar TSE corporate financing function.     

Price Controls and Market Structure: Evidence from Gasoline Retail Markets

In this paper we study the effect of price floor regulations on the organization and performance of markets. The standard interpretation of the effects of these policies is concerned with short‐run market distortions associated with excess supply. Since price controls prevent markets from clearing, they lead to higher prices. While this analysis may be correct in the short‐run, it does not consider the dynamic equilibrium consequences of price controls. We demonstrate that price floor regulations can have important long‐run effects on the the structure of markets by crowding them and creating endogenous barriers to entry for low‐cost retailers. Moreover, we show that these factors can indirectly lower productivity and possibly even prices. We test this in the context of an actual regulation imposed in the retail gasoline market in the Canadian province of Québec and show that the policy led to more competition between smaller/less efficient stations. This resulted in lowered sales, and, despite the reduction in efficiency, did not increase prices.     

Emigration intentions of Roma: evidence from Central and South-East Europe

The Roma constitute the largest, poorest and youngest ethnic minority group in Europe. Over the last few years, they have attracted unprecedented attention with the fear of massive waves of emigrants to Western European countries. Using unique comparative data from 12 Central and South-East European countries, we study the pattern and determinants of Roma emigration intentions. We find that plans to go abroad are more frequent among Roma compared to non-Roma, but the ethnic gap in emigration intentions is not explained by the more disadvantaged characteristics of Roma compared to non-Roma. Among the Roma population, potential emigrants are more educated and wealthier on average. Finally, ethnic discrimination is a very influential factor that explains the intentions to emigrate within the Roma population.     

Impact of Advance Notice Periods on the Performance Persistence of Hedge Funds

This paper examines the impact of the advance notice period on hedge fund performance persistence in investors＇ portfolios. As investors in hedge funds face several trading restrictions related to the funds＇ common investment terms and conditions, it is hypothesized that the advance notice period generates illiquidity for investors and impairs their ability to benefit from performance persistence in hedge funds. Using a sample of 4,788 hedge funds over a period from 1994 to 2008 and contingency table based standard methodology for returns and Sharpe ratios, the results suggest that accounting for individual funds＇ advance notice periods has a negative impact on the performance persistence of hedge funds. The proportion of significantly persistent funds declines when incorporating the advance notice period, especially for short time horizons. Furthermore, a considerable part of hedge fund performance persistence is related to asset class-specific terms and conditions, reducing the amount of short-term performance persistence in practice.     

Existence of Nash networks in one-way flow models

This paper addresses the existence of Nash equilibria in one-way flow models in a number of different settings. In these models players form costly links with other players and obtain resources from them through the directed path connecting them. We find that heterogeneity in the costs of establishing links plays a crucial role for the existence of Nash networks. The paper also provides conditions for the existence of Nash networks in models where costs and values of links are heterogeneous. We would like to thank an anonymous referee for useful suggestions.
