Indivisibilities,lotteries, and sunspot equilibria

Summary We analyze economies with indivisible commodities. There are two reasons for doing so. First, we extend and provide some new insights into sunspot equilibrium theory. Finite competitive economies with perfect markets and convex consumption sets do not allow sunspot equilibria; these same economies with nonconvex consumption sets do, and they have several properties that can never arise in convex environments. Second, we provide a reinterpretation of the employment lotteries used in contract theory and in macroeconomic models with indivisible labor. We show how socially optimal employment lotteries can be decentralized as competitive equilibria without lotteries once sunspots are introduced.We thank Kenneth Arrow, Aditya Goenka, Ed Green, Jeremy Greenwood, Walter Heller, Steve Matthews, Herve Moulin, Roger Meyerson, Jim Peck, Patrick Kehoe, Ramon Marimon, Ed Prescott, Richard Rogerson, Nancy Stokey and Raghu Sundaram for their comments.

SLUM DWELLERS' HOUSEHOLD CONSUMPTION PATTERN AND ITS IMPLICATION FOR COST RECOVERY IN SLUM UPGRADING: Evidence from Dhaka, Bangladesh

Strong emphasis has recently been placed on recovery of improvement costs from slum dwellers for sustainable development of low-income urban settlements. Furthermore, socio-economic stratification of slum dwellers is perceived to influence their consumption and investment patterns in the city. Against this background, populations in six slums in Dhaka, stratified into house owners and renters, were studied. Results show that renters have stronger ties with their rural origin where they are likely to return and remit a significant portion of their income, leaving a limited amount for consumption and investment in the city. In contrast, owners have stronger attachment to the city, remit negligible amounts to their village of origin and pay more attention to city consumption and investment. Consequently, any cost recovery approach to slum upgrading implies heavy reliance on owners. But renters can also be expected to share the cost, to some limited extent, in the form of property tax or community services charges. The key point here is the concurrence of renters and owners on the sharing of costs and benefits.     

Reply on comment to “small firms and the merger mania”

Research on performance differences between small and large firms is booming. It emerges relatively separated from the mainstream Industrial Organization Literature. Inspired by Levy's comment on an earlier paper we try to bridge the gap between the two areas. Especially we screen non cooperative game theoretical models for predictions on performance differences. Most of them forecast higher profits for larger firms, but there exist also some models which predict the opposite for very specific circumstances.     

On Weitzman's ‘recession resistant’ employee compensation arrangements

This note presents a slight modification of the alternative pay systems discussed by Weitzman (1983). The modification preserves the recession resistance property, yet guarantees that the workers already in the firm, will not become worse off by the conversion to the new pay system even when no other firm converts to it.     

The North American Free Trade Agreement and the Canadian Agri-Food Sector

In the past five years, Canada has negotiated and ratified three trade agreements: the Canada-United States Free Trade Agreement (FTA), the North American Free Trade Agreement (NAFTA) and the multilateral free trade agreement now administered by the World Trade Organization (WTO). This paper focuses on the implications for agri-food trade of the NAFTA and its interface with the other two agreements. The provisions of the NAFTA are described and evaluated as they relate to market access, domestic support, export assistance, technical regulations and dispute settlement. Observations are presented on the NAFTA's potential effects on trade in red meats, grains and oilseeds, supply-managed commodities and horticulture. In addition, some of the shortcomings of the NAFTA are highlighted.
