Penny Stock IPOs

We examine underpricing, long-run returns, lockup periods, and gross spreads for penny stock IPOs over the 1990–1998 period. We find that penny stock IPOs have higher initial returns than ordinary IPOs, but significantly worse long-run underperformance. We also find that penny stock IPOs have longer lockup periods and larger gross spreads. To explore the effect of potential market manipulation, we examine IPOs led by a group of underwriters that were the subject of SEC enforcement actions and/or other penalties. Penny stock issues led by these banks are particularly underpriced and underperform ordinary IPOs led by other underwriters.     

Monetary policy and the daily behavior of interest rates

It is possible that previous research has failed to detect significant variation in the ex-ante real interest rate because the Federal Reserve follows a policy designed to stabilize the real rate. If the Fed is successful, there will be little month-to-month variation in the real rate. Nonetheless, research to date has relied on monthly or quarterly data. This paper presents the results of new tests that use daily data in an attempt to detect short-term variation in the ex-ante real rate. Though the tests reveal that the real rate is not constant, most of the detected variation is related to reserve settlement on Wednesday.     

Welfare Reform and the Well-Being of Single Female-Headed Families: A Semi-Parametric Analysis

Single female-headed families with children (SFHFwC) have historically been the primary recipients of federal public cash assistance payments in the United States. Recent welfare reform initiatives established work requirements and cumulative time limits on public cash assistance payments. Three findings in this paper have significant implications for the long-term efficacy of welfare reform initiatives. First, SFHFwC made significant and broad-based gains in their economic well-being from 1993 to 1999. Second, increased propensities of single mothers to leave welfare and enter the workforce from 1993 to 1999, behavior consistent with incentives created by welfare reform measures, do not account for a major portion of these observed gains. Third, improved area economic conditions and increased educational levels of single mothers account for a major share of gains in well-being.     

Trends in University Ag-Biotech Patent Production

This work exploits information on U.S. patents to identify trends in university ag-biotech patenting and citation performance. It sets forth some key issues concerning patterns of university ag-biotech patenting and then provides an empirical analysis of the evolving trends. Land grant universities account for most U.S. ag-biotech patents. The data show a path-dependent innovation pattern, in which there also seems to be a culture of patenting that develops at certain universities. Evidence shows that ag-biotech patents are more cited than the average university patent. Inequalities across land grant universities are also evident in the production of ag-biotech patents, although perhaps not to a much greater degree than underlying inequalities in funding and research qualities. The paper closes by considering how the evidence offered might be used to advance the public discussion regarding trends in agricultural biotechnology research in the United States.     

Managing conflict to improve the effectiveness of retail networks

Retailers are becoming involved with networks consisting of multiple firms in order to more effectively perform business activities such as supply chain management. This research develops and tests a framework outlining the effects of conflict in networks and how conflict management can mitigate and exacerbate these effects. A study of 81 simulated networks finds that inter-personal and task conflict have a negative effect on network member satisfaction and desire to be a member of the network. The use of a collaborative conflict management style has a positive effect on satisfaction and desire for continuity, but the effects of accommodative and confrontational styles depend on the level of inter-personal and task conflict present in the network.     

Efficiency and technological change at US research universities

This article investigates the determinants of efficiency and technological progress at US research universities. It relies on a unique panel data set of multiple outputs and inputs from 92 universities covering the period 1981–1998. Over that time span, US universities experienced large increases in industry funding and in academic patenting activity. In this context, the directional distance function and a nonparametric representation of the underlying production technology are combined to obtain estimates of productivity growth and technical efficiency. An econometric analysis is then presented to examine the determinants of technical efficiency and the rate of technological progress. The results show how changes in funding sources for US research universities affects research performance.     

The impact of institutional sources of capital upon the minority-oriented venture capital industry

Venture capital (VC) funds specializing in investing equity capital in minority-owned businesses have grown rapidly over the past decade, fueled by the willingness of major institutional investors to support this traditionally neglected niche. We investigate impacts of public pension funds upon the minority VC sector. These funds, providing over half of all capital invested in minority VCs, selectively invest, seeking to fund only those VCs likely to generate high returns. Although they attempt to pick the winners, our findings indicate that they have failed to do so. The influence of public pension funds upon the minority VCs is nonetheless real, skewing investing away from traditional practices and toward those of the venture capital mainstream. In the process, minority VCs funded by pension fund money invest in high-tech fields more than other minority-oriented VC funds do. Further, they are less likely to fund minority-owned small firms, focusing increasingly upon firms owned by nonminority Whites. Neither of these trends has resulted in increased returns. Rather, diverting minority-oriented VCs away from their traditional mission of investing in minority firms operating in a broad range of industries has resulted in lower returns over the years studied.
