MEETINGS AND MECHANISMS

This article shows how meeting frictions affect equilibrium trading mechanisms and allocations in an environment where identical sellers post mechanisms to compete for buyers with ex ante heterogeneous private valuations. Multiple submarkets can emerge, each consisting of all sellers posting a particular mechanism and the buyers who visit those sellers. Under mild conditions, high-valuation buyers are all located in the same submarket, and low valuation buyers can be in: (i) the same submarket, (ii) a different submarket, and (iii) a mixture of (i) and (ii). The decentralized equilibrium is efficient when sellers can post auctions with reserve prices or entry fees.     

What India Can Learn from China and Vice Versa

A partial convergence of the Indian and Chinese growth models is likely. Judging from China's experience, sustaining India's impressive economic performance of recent years will require a significant further opening of its economy (externally and internally), higher savings and investments, especially in physical infrastructure and social services, and stronger labor absorption in the modern sectors. The base of India's current economic boom - software, IT-related services and high-end manufacturing - is narrow compared to China's. Poor performance in agriculture is responsible for still significant poverty in many parts of rural India. Bilateral India-China ties, including trade and investment, are increasing rapidly and could help to bring about the structural economic changes India needs. Through its exports to China, India is becoming linked to global supply chains centered on China. The notion that India-China relations are, or are bound to become, fundamentally antagonistic, held by many in the USA, is mistaken and potentially dangerous.     

The Opportunity Cost of Negative Screening in Socially Responsible Investing

This paper investigates the impact of negative screening on the investment universe as well as on financial performance. We come up with a novel identification process and as such depart from mainstream socially responsible investing literature by concentrating on individual firms’ conduct and by studying a much wider range of issues. Firstly, we study the size and financial performance of fourteen potentially controversial issues: abortion, adult entertainment, alcohol, animal testing, contraceptives, controversial weapons, fur, gambling, genetic engineering, meat, nuclear power, pork, (embryonic) stem cells, and tobacco. We investigate an international sample of more than 1,600 stocks for more than twenty years. We then analyze the impact of applying negative screens to a market portfolio. Our findings suggest that the choice for negative screening strategies does matter for the size of the investment universe as well as for risk-adjusted return performance. Investing in controversial stocks in many cases results in additional risk-adjusted returns, whereas excluding them may reduce financial performance. These findings suggest that there are opportunity costs to negative screening.     

A framework for risk criteria for critical infrastructures: fundamentals and case studies in the Netherlands

Critical infrastructures are complex societal systems. For that reason, risk criteria for critical infrastructures are also ‘part’ of the risk criteria for complex societal systems. The questions to be resolved are: (1) are the societal risk criteria of complex systems defined and quantifiable; and (2) is it known how the risk criteria of critical infrastructures relate to the risk criteria of the complex system as a whole. In other words, what certainty is there that the risk criteria of critical infrastructures meet the risk criteria of complex systems as a whole. A complex system in this respect may be a society as a whole, e.g. a nation.     

The Right Man for the Job

This paper describes a search model with a continuum of worker and job types, free entry and transferable utility. We apply a second-order Taylor expansion to characterize the equilibrium, derive the "cost of search" and show that it is decreasing in the substitutability of worker types. This cost of search is then decomposed into three components: unemployment, vacancy costs and mismatch. Our contact technology rules out congestion effects between different worker types and therefore exhibits increasing returns to scale. One third of those increasing returns in contacts are shown to be absorbed by firms and workers being more choosy. The resulting equilibrium is not efficient. Unemployment benefits can reduce the loss by serving as a search subsidy. Numerical simulations of the model show that our Taylor expansions are quite accurate.
