Economic status of households and labour supply to market and non-market activities mdash; some results from a poor rural economy

Assuming a given underlying utility structure for all households, we have demonstrated that the differential labour supply behaviour among household categories results owing to the different sets of constraints they face depending on their economic status and asset ownership. Using the criteria implied by the theoretical model four household gorups are defined. The labour supply functions estimated for these four groups support the theoretical result of significantly different supply behaviour. The empirical exercise, as expected, indicates that the labour supply decision of the subsistence group is guided by their need to achieve the minimum level of consumption while the middle-income households, who do not have enough non-labour income to meet their minimum subsistence need, tend to work longer hours in market activities than the workers from high-income households. However, market labour supply by high-income households is found to be relatively more sensitive to changes in the wage rate. The behaviour of the household groups differ so significantly that if an aggregate model is estimated ignoring inter-household differences, the predicted hours will grossly over-estimate labour supply to market activities.     

A Model of Sponsorship Effects on the Sponsor's Employees

Drawing from the corporate sponsorship literature, a model is developed that seeks to explain how externally directed corporate sponsorship can influence the behavior of the sponsor's employees. External sponsorship conveys a signal that can impact on employees’ perceptions of their employer. The model seeks to explain the processes and types of possible impacts. Although the model requires confirmation, its conceptualization raises additional avenues to assess the benefits of corporate sponsorship.     

Willingness to Pay for Pesticide Free Fruits: Evidence from Pakistan

ABSTRACT

This paper analyzes factors influencing consumption decision of pesticide free fruits (PFF) and estimates the willingness to pay (WTP) price premium for PFF in Pakistan. A contingent valuation survey of 200 households was conducted using face to face interview and payment card method. Results suggested that 93.5% respondents were WTP higher prices for PFF. Remarkably, around 35% respondents were WTP 16–20% higher prices and 24% respondents were WTP 6–10% higher prices for PFF than the existed conventional price. In addition, our ordered logit regression suggests that demographic and socio-economic variables such as age, education, income, household’s size and perception about health benefits are significantly associated with higher WTP for PFF.     

The Harris-Todaro hypothesis and the Heckscher-Ohlin-Samuelson trade model : A synthesis

We report a model of the Harris-Todaro variety in which capital is mobile and the urban wage is endogenous. Our model subsumes several other models presented in the literature. We extend the central theorems of trade to our model and also present formulae for the shadow wage and shadow rental. Our principal findings include (a) nonexistence of equilibrium in an important specialization of the model; (b) a factor-price and unemployment rate equalization theorem: and (c) an identical subsidy to labor but a differential subsidy to capital for obtaining a second-best optimum.     

Exact arbitrage, well-diversified portfolios and asset pricing in large markets

For a market with an atomless continuum of assets, we formulate the intuitive idea of a “well-diversified” portfolio, and present a notion of “exact arbitrage”, strictly weaker than the more conventional notion of “asymptotic arbitrage”, and necessary and sufficient for the validity of an APT pricing formula. Our formula involves “essential” risk, one based on a specific index portfolio constructed from factors and factor loadings that are endogenously extracted to satisfy an optimality property involving a finite number of factors. We illustrate how our results can be translated to markets with a large but finite number of assets.     

Self-Interest, Self-Deception and the Ethics of Commerce

On taking the common distinction between the legal and the ethical as a point of departure, and in an effort to understand Marshall's approach to self-interest, and thereby to his conception of an ethics of commerce, I read three of his essays in the light of some non-technical writings of Frank Hahn and three other Cambridge intellectuals. My larger project connects self-interest and self-deception to a possible ethics of theorizing in economics, and thereby to the ethics of the relationship between the theorist and the theorized, the analyst and the analyzed.

Dual Domestic Listing, Market Structure and Shareholder Wealth

This paper examines the impact of dual domestic listing of common stocks on shareholder wealth. The sample contains 137 AMEX- and NYSE-listed companies that dually listed their common stocks on the Pacific and Midwest Stock Exchanges between 1984 and 1988. Because the sample stocks do not have unlisted trading privileges, dual listing changes the market structure in which the stocks traded. Changes in market structure may affect stock returns through the liquidity services provided by the competing markets and through the possible nonhomogeneous clientele across markets. Using standard event methodology to examine stock market behavior around dual listing shows that the net effect of dual listing on returns is negative. Such negative returns suggest that corporate managers have reasons for dual domestic listing other than increasing shareholder wealth.
