Communication and authority with a partially informed expert

A sender‐receiver game a la Crawford‐Sobel is analyzed where the sender has expertise on some but not all the payoff‐relevant factors. This residual uncertainty can either improve (even allow full revelation) or worsen the quality of transmitted information depending on a statistic called the effective bias. For symmetrically distributed residual uncertainty or quadratic loss functions, (i) the quality of information transmission is independent of the riskiness of residual uncertainty, (ii) it may be suboptimal to allocate authority to the informed player, (iii) despite players' preferences being arbitrarily close, it is impossible to assert that the receiver prefers delegation over authority or vice versa.     

Diseases, infection dynamics, and development

The relationship between health and development is a subject of ongoing debate. This paper contributes to the debate by proposing a general equilibrium theory of infectious disease transmission, prevention investment, and rational behavior. Diseases cause premature death, labor productivity loss and lower quality of life. Higher disease prevalence lowers the average saving-investment propensity. The model offers two insights. First, infectious disease can plausibly generate an unconventional growth trap where income alone cannot push an economy out of underdevelopment. Second, even when countries converge to the same balanced growth path, the disease ecology significantly impairs the pace of economic development.     

Impact of injuries on work performance among the surgical blacksmiths of West Bengal

The manufacture of surgical instruments is one of the leading small-scale industrial sectors in West Bengal, India. The present study was undertaken to assess the rate, type and cause of injury incidents among surgical blacksmiths and whether these incidents affected the work performance of the blacksmiths. A cluster of 216 skilled and 225 unskilled blacksmiths (male), engaged in the manufacture of surgical instruments, was selected from Baruipur subdivision as study subjects. The study included: 1) completion of a questionnaire; 2) measurement of physical parameters; 3) incident records; 4) statistical analysis of the data. The present study revealed that the blacksmiths suffered very frequently from work-related injuries. The number of injuries that occurred during 2004 - 2005 for skilled and unskilled blacksmiths was 1413 and 1610 respectively. Unskilled blacksmiths were disproportionately affected. These injuries resulted in a high rate of lost workdays, i.e. 517 and 742 workdays for skilled and unskilled workers respectively. The study thus indicated that surgical blacksmiths are highly prone to injuries in their occupation, mostly affecting the fingers (23% and 23%) and back region (21.7% and 22%) in both groups, which consequently affected their health, productivity and work performance.     

Low level equilibrium trap,unemployment, efficiency of education system,child labour and human capital formation

This paper builds an overlapping generations household economy model to examine the impact of adult unemployment on the human capital formation of a child and on child labour, as viewed through the lens of the adult’s expectations of future employability. The model indicates that the higher the adult unemployment rate in the skilled sector, the lesser is the time allocated by an unskilled adult towards schooling of her child. We also find that an increase in the unskilled adult’s wage may or may not decrease child labour in the presence of unemployment. The model predicts that an increase in child wage increases schooling and human capital growth rate only if the adults in the unskilled sector earn less than subsistence consumption expenditure. As the responsiveness of skilled wage to human capital increases, schooling and human capital growth rates increase. The model dynamics bring out the importance of education efficiency and parental human capital in human capital formation of the child. In the case of an inefficient education system, generations will be trapped into low level equilibrium. Only in the presence of an efficient education system, steady growth of human capital is possible. Suitable policies that may be framed to escape the child labour trap are discussed as well.     

Bundling decisions for selling multiple objects

Summary. Auctioneers often face the decision of whether to bundle two or more different objects before selling them. Under a Vickrey auction (or any other revenue equivalent auction form) there is a unique critical number for each pair of objects such that when the number of bidders is fewer than that critical number the seller strictly prefers a bundled sale and when there are more bidders the seller prefers unbundled sales. This property holds even when the valuations for the objects are correlated for a given bidder. The results have been proved using a mathematical technique of quantiles that can be extremely useful for similar analysis. Received: November 5, 1996; revised version: January 21, 1998     

Private Equity as Canary in a Coal Mine: Building the Ecosystem for Effective Global Financial Integration

A burgeoning private equity (PE) industry provides investment capital to build the capacity of an economy for innovation and entrepreneurial growth. We argue that for PE to contribute to this, capacity building requires effective systems for allocation of financial capital to the private sector and an ecosystem of supportive organizations. To illustrate these claims, we review the recent history of PE in the Middle East–North Africa region to contrast the PE industry in Middle East–North Africa, which stagnated after the financial crisis, with the industry in Turkey, which recovered quickly from a brief pause after the crisis and has thrived since 2008.

Rational functions: an alternative approach to asset pricing

This paper shows that asset prices are linear polynomials of various underlying explanatory factors and asset returns being ratios of these polynomials, are rational functions that do not add linearly when averaging. Hence, average returns should be modeled based on stock prices. However, continuous returns may be treated as approximately linear across time and modeled directly. Our new Rational Function (RF) models, empirically outperform the traditional asset pricing models like the Capital Asset Pricing Model (CAPM) and the Fama–French three and five-factor models for both average and continuous returns. Moreover, the RF theory also provides a model to estimate the asset volumes. The average change in asset volumes together with average returns provide the estimates for average change in market values of assets. Thus, the RF model approach can be used to select assets that provide either highest returns for profit maximization or highest change in market values for wealth maximization for given levels of risk.     

Best foot forward or best for last in a sequential auction?

Should a seller with private information sell the best or worst goods first? Considering the sequential auction of two stochastically equivalent goods, we find that the seller has an incentive to impress buyers by selling the better good first because the seller's sequencing strategy endogenously generates correlation in the values of the goods across periods. When this impression effect is strong enough, selling the better good first is the unique pure‐strategy equilibrium. By credibly revealing to all buyers the seller's ranking of the goods, an equilibrium strategy of sequencing the goods reduces buyer information rents and increases expected revenues in accordance with the linkage principle.     

Bank-based versus market-based financial systems: A growth-theoretic analysis

We study bank-based and market-based financial systems in an endogenous growth model. Lending to firms is fraught with moral hazard as owner-managers may reduce investment profitability to enjoy private benefits. Bank monitoring partially resolves the agency problem, while market-finance is more ‘hands-off’. A bank-based or market-based system emerges from firm-financing choices. Neither system is unequivocally better for growth, which crucially depends on the efficiency of financial and legal institutions. But a bank-based system outperforms a market-based one along other dimensions. Investment and per capita income are higher, and income inequality lower, under a bank-based system. Bank-based systems are also more conducive for broad-based industrialization.
