This paper sheds light on intrafamilial gifts for housing. By using Austrian intergenerational survey data various questions are addressed. First, is familial aid more or less widespread in given social strata? Second, what are the determinants and motives for family gifts? And third, what are the possible impacts on the choice set of their recipients? Probit estimates show that gifts significantly depend on the parents lifetime financial position, consistent with life cycle permanent income (LCPI) approaches. Gifts to remove liquidity constraints are more difficult to reconcile with LCPI. “Dynastic” gifts that support household formation and ownership acquisition may be interpreted as intergenerational exchange. They occur more frequently than periodical cash transfers where altruistic behavior cannot be ruled out.  相似文献

Both economists and sociologists generally recognize the importance of reputation in coordinating economic transactions. In a perfectly competitive and anonymous market characterized by faceless buyers and sellers, the issue of reputation would be irrelevant and unnecessary. In reality, however, markets are often filled with varying degrees of information asymmetry, which can threaten the very existence of the market system itself. In critical reaction to the standard neoclassical model, some economists, on the one hand, argue that when there is an information problem, reputation serves as a valuable source of market signal of quality. Sociologists of economic life similarly contend that reputation, along with trust, is critical in lowering transaction costs and thereby facilitating various economic activities among individual actors. The purpose of this article is to apply this broad theoretical observation to a specific empirical phenomenon. It does so by highlighting the role of social networks that connect actors on both demand and supply sides of the market. Specifically, this study examines how interpersonal networks in the market for legal services affect the duration of ties between buyers and sellers. Quantitative analysis based on a random sample of Chicago lawyers, a project funded by the American Bar Foundation, reveals that ceteris paribus the lawyer-client relations are significantly driven by social network factors.  相似文献

Abstract. We study how restricting CO2 emissions affects resource prices and depletion over time. We use a Hotelling‐style model with two non‐renewable fossil fuels that differ in their carbon content (e.g., coal and natural gas) and in addition are imperfect substitutes in final good production. We show that an economy facing a CO2 flow‐constraint may substitute towards the relatively dirty input. As the economy tries to maximize output per unit of emissions it is not only carbon content that matters: productivity matters as well. With an announced constraint the economy first substitutes towards the less productive input such that more of the productive input is available when constrained. Preliminary empirical results suggest that it is cost‐effective to substitute away from dirty coal to cleaner oil or gas, but to substitute from natural gas towards the dirtier input oil.  相似文献
