This paper uses newly available data on plant level regulatory status linked to the Census Longitudinal Business Database to measure the impact of changes in county level environmental regulations on plant and sector employment levels. Estimates from a variety of specifications suggest a strong connection between changes in environmental regulatory stringency and both employment growth and levels in the affected sectors. The preferred estimates suggest that changes in county level regulatory status due to the 1990 Clean Air Act Amendments reduced the size of the regulated sector by as much as 15 percent in the 10 years following the changes.

Racial restrictive covenants are private agreements prohibiting sale, rental, use or occupancy of properties by persons of designated races, ethnicities, nationalities and religions. Widely acknowledged for facilitating residential segregation, the Supreme Court ruled covenants unenforceable in 1948. Yet they remained legal to write and reference, allowing realtors, banks, insurers, title companies and government agencies to continue to rely on unenforceable covenants in their decisions and policies. Beyond legal enforceability, covenants were essentially signals that coordinated the behavior of a variety of private individual and institutional actors—signals that remained effective without the courts. Evidence is presented to support this claim.

According to the terms-of-trade theory, governments use trade agreements to escape from a terms-of-trade-driven prisoner's dilemma. We use the terms-of-trade theory to develop a relationship that predicts negotiated tariff levels on the basis of pre-negotiation data: tariffs, import volumes and prices, and trade elasticities. We then confront this predicted relationship with data on the outcomes of tariff negotiations associated with the accession of new members to the World Trade Organization. We find strong and robust support for the central predictions of the terms-of-trade theory in the observed pattern of negotiated tariff cuts. (JEL F11, F13)

Because wines are aged for several years before they are released, newly hired winemakers arrive as wines made by their predecessors enter the market. An analysis of winemaker hiring events reveals that wines released right after a new winemaker's arrival from a prominent competitor are priced significantly higher than corresponding wines released in the preceding year. However, the wines released before and after the hiring event are indistinguishable in terms of quality. These findings isolate a “purely symbolic” effect of employee mobility, which affirm sociological accounts of markets—under conditions of uncertainty, inter-organizational affiliations condition producers' returns to quality demonstrations.

Evidence from a nationally representative sample of households illuminates the determinants of recycling behavior for plastic water bottles. Private values of the environment are influential in promoting recycling, as are personal norms for pro-environmental behavior. However, social norms with respect to the assessment of the household's recycling behaviors by others have little independent effect. Particularly influential are policies that create economic incentives to promote recycling either through state recycling laws that reduce the time and inconvenience costs of recycling or through bottle deposits. Effective policies can have a discontinuous effect at the individual level, transforming non-recyclers into avid recyclers.
