We provide evidence that firms attempting IPOs condition offer terms and the decision whether to carry through with an offering on the experience of their primary market contemporaries. Moreover, while initial returns and IPO volume are positively correlated in the aggregate, the correlation is negative among contemporaneous offerings subject to a common valuation factor. Our findings are consistent with investment banks implicitly bundling offerings subject to a common valuation factor to achieve more equitable internalization of information production costs and thereby preventing coordination failures in primary equity markets.

An important class of active labor market policy has received little impact evaluation: immigration barriers intended to raise wages and employment by shrinking labor supply. Theories of endogenous technical advance raise the possibility of limited or even perverse impact. We study a natural policy experiment: the exclusion of almost half a million Mexican bracero farm workers from the United States to improve farm labor market conditions. With novel labor market data we measure state-level exposure to exclusion, and model the absent changes in technology or crop mix. We fail to reject zero labor market impact, inconsistent with this model.

One long-standing hypothesis about science and engineering labor markets is that the supply of highly skilled workers is likely to be inelastic in the short run. We consider the market for computer scientists and electrical engineers (IT workers) and the evolution of wages and employment through two periods of increased demand. Relative to the boom of the 1970s, the demand shock in the 1990s generated relatively greater changes in employment and smaller changes in wages. The growth in the pool of skilled workers abroad, combined with increased immigration in high-skill fields, is central to this story.

The present article is an attempt to resolve the controversies concerning the concept of barriers to entry. We begin by contrasting the definitions of an entry barrier proposed in the economics literature. We then introduce a classification system to clear up the existing confusion, and we employ it to assess the nature of the barriers posed by scale economies and sunk costs.

Using path analysis, we investigate the direct and indirect links between three measures of earnings quality and the cost of equity. Our investigation is motivated by analytical models that specify both a direct link and an indirect link that is mediated by information asymmetry, but do not suggest which link would be more important empirically. We measure information asymmetry as both the adverse selection component of the bid-ask spread and the probability of informed trading (PIN). For a large sample of Value Line firms during 1993–2005, we find statistically reliable evidence of both a direct path from earnings quality to the cost of equity, and an indirect path that is mediated by information asymmetry, with the weight of the evidence favoring the direct path as the more important.

The federal tax code provides preferential treatment for the production and use of renewable energy. We report estimates of the subsidies' effects on greenhouse gases (GHG) emissions developed in a recent National Research Council (NRC) Report. Due to lack of estimates of the impact of tax provisions on GHG emissions, new modeling studies were commissioned. The studies found, at best, a small impact of subsidies in reducing GHG emissions; in some cases, emissions increased. The NRC report also identified the need to capture the complex interactions among subsidies, pre-existing regulations, and commodity markets.

Was the Depression forecastable? After the crash, how long should it have taken contempo rary forecasters to realize how severe the downturn was going to be? These questions are addressed by studying the predictions of the Harv ard Economic Service and Yale's Irving Fisher during 1929 and the ear ly 1930s. The data assembled by the Harvard and Yale forecasters, tog ether with modern historical data, are subjected to statistical analy sis to learn whether their verbal pronouncements were consistent with the data. Both the Harvard and Yale forecasters were systematically too optimistic. Yet, nothing in the data suggests that the optimism w as unwarranted.
