Ronald Coase's Method of Building More Realistic Models of Choice

This paper argues that Ronald Coase's major contributions to economic theory are best understood in terms of the distinct method he used to build more realistic models of choice. We call his method the benchmark-comparison method. It consists of building models of choice and then using them as benchmarks in the further investigation of economic interaction, either by comparing the benchmark models with observed interaction or by building additional models of choice, which may themselves function as benchmarks. The paper first describes the method then demonstrates how Coase used it in his two most famous papers. We go on to show how an understanding of the method confirms Coase's own statements about the continuity of his thought. Finally, we assess Coase's critique of Milton Friedman's positivist methodology and discuss a recent paper on Coase's methodology.     

Consumption smoothing and vulnerability in Russia

Applying bootstrapped quantile regression to the Russian Longitudinal Monitoring Survey (RLMS) data, we examine the channels through which individuals experience and seek to cope with changes in consumption. We find that married individuals living in small households, with educated heads in urban areas are better equipped to smooth consumption. Investigating the impact of idiosyncratic shocks, we find that the labour market is an important transmission mechanism allowing households to smooth their consumption but also exposing them to risk, mainly through job loss. Outside of pension payments, the formal social safety net does not facilitate consumption smoothing, thus heightening the importance of informal coping institutions. It transpires that both support from relatives/friends and home production act as important insurance mechanisms for the most vulnerable. In contrast with previous findings, it would seem that regardless of its historical, political and social roots, the garden plots and dachas, often romanticized in Russian literature, do provide a means by which ‘urban’ Russians are able to cope with economic fluctuations. We finish by stressing the important policy lessons for Russia's developing market economy.     

First-author conditions: evidence from finance journal coauthorship

We study the trend and the author name-ordering rule in finance publication using the publication records of 21 core finance journals during the period from 1990 to 2004. We empirically model the underlying factors that affect the alphabetical ordering rule among multi-authored finance articles. We find that the choice of alphabetical ordering is based on the quality of the article, institutional heterogeneity, team size and cultural factors. The central argument rests upon the need to signal and the importance of signalling within the context of bargaining behaviour among coauthors. The probability of choosing alphabetical name ordering rule is associated with high article quality, higher ranked institutions, smaller research team and the presence of European authors.     

Bounded rationality,expectations, and child labour

This paper develops a model with overlapping generations, where the household's optimal fertility, child labour, and education decisions depend on the parents’ expectations or beliefs about the return to education. It is shown that there exists a range of parental income where the fertility rate is high and children participate in the labour market and receive an incomplete education if a parent believes the return to education is low. The act of participating in the labour market reduces the child's ability to accumulate human capital; thus, the action of sending a child into the labour market is sufficient to ensure that the parents’ initially pessimistic expectations are fulfilled. It is then shown that a one‐time policy intervention, such as banning child labour and mandatory education, can be enough to move a country from the positive child labour equilibrium to an equilibrium with no child labour.     

HIV/AIDS AND BANKING STABILITY IN DEVELOPING COUNTRIES

We argue that the recent large increase in deposits’ turnover in many developing countries with high HIV/AIDS prevalence is associated with the spread of the disease. The point is that the need to pay for individual treatments force large‐scale withdrawals of households’ deposits, and that those large withdrawals put the banking industry at risk. In a standard demand‐deposit model where the HIV/AIDS prevalence among depositors is random, we show that (1) the probability of a large‐scale banking failure without a bank run increases as the odds of any prevalence level increases, and (2) it is always optimal to deposit, and thus to accept the risk of banking failure, to maintain long‐term investments in place.     

TRANSATLANTIC CAPITAL MARKET PRICE DISCOVERY DURING A FINANCIAL CRISIS

Previous results show relatively small amounts of time variation in the Hasbrouck (1995) information share across international markets. Using data from a security that was cross‐listed on the New York and London Stock Exchanges in the 1860s, we find that the information share changes dramatically during a financial crisis that began in the foreign market.     

ROY MODEL SORTING AND NONRANDOM SELECTION IN THE VALUATION OF A STATISTICAL LIFE*

Wage‐hedonics is used to recover the value of a statistical life (VSL) by exploiting the fact that workers choosing riskier occupations are compensated with a higher wage. Roy (Oxford Economic Papers 3 (1951), 135–46) suggests that observed wage distributions will be distorted if individuals choose jobs according to idiosyncratic returns. We describe how this type of sorting biases wage‐hedonic VSL estimates and implement two new estimation strategies that correct that bias. Using data from the Current Population Surveys, we recover VSL estimates that are three to four times larger than those based on the traditional techniques, statistically significant, and robust to a wide array of specifications.     

The Effects of Future Capital Investment and R&D Expenditures on Firms' Liquidity

The paper explores factors that lead to accumulation or decumulation of firms' cash reserves. In particular, the paper empirically examines whether additional future fixed capital and R&D investment expenditures induce firms to change their liquidity ratio while considering the role of market imperfections. Implementing a dynamic framework on a panel of US, UK, and German firms, it is found that firms in all three countries make larger adjustments to cash holdings when they plan additional future R&D rather than fixed capital investment expenditures. This behavior is particularly prevalent among financially constrained firms.
