Buyer search and price dispersion: a laboratory study

We study markets with costly buyer search in which sellers simultaneously post prices. Buyers costlessly observe one or (with probability 1−q) two of the posted prices, and can accept one or pay to search again. The experiment varies q, the search cost, and the number of buyers. Equilibrium theory predicts a unified very low (high) price for q=0 (q=1) and predicts specific distributions of dispersed prices for q=1/3 and 2/3. Actual prices conform closely to the predictions in some treatments. Buyers’ reservation prices are biased away from the extremes, however, and sellers’ prices have positive autocorrelation and cross-sectional correlation.     

Crowd-out and diversity

Research has shown that altruism is lower in diverse communities. Can this phenomenon be counteracted by government intervention? To answer this question, this paper introduces diversity to the canonical model of “warm glow” giving. Diversity may have two effects on incentives: it may attenuate individuals' altruistic preferences for public goods, and it may “cool off” the warm glow that individuals get from voluntarism. Either of these effects leads to diverse communities having lower levels of public goods, consistent with prior research. However, these effects have opposite implications for the efficacy of government intervention. I then empirically investigate whether government intervention is more effective in diverse communities. For identification, I exploit the Supreme Court-mandated 1991 expansion of the SSI program. Using a new dataset of United Methodist churches from 1984 to 2000, the results show that the expansion of SSI crowded-out charitable spending by churches. The crowd-out estimate for the average church is reasonably large, but this masks significant differences in crowd-out between communities. Crowd-out occurred almost entirely in relatively homogeneous communities; there is only modest evidence of crowd-out in racially diverse communities. Thus diverse communities, while having the lowest levels of altruism, are in this instance the most amenable to government intervention.     

Why risk popular ratification failure? A comparative analysis of the choice of the ratification instrument in the 25 Member States of the EU

Following the European integration history, referenda are a risky ratification strategy. Despite establishing a convention and intense treaty negotiations, an unprecedented number of eleven member states announced a referendum for the ratification of the constitutional treaty in 2004, two of them finally failed and stalled the ratification process. This study examines the choice of the ratification instrument by an empirical analysis of the strategic interaction between government, opposition parties and the electorate in the 25 ratification countries. Our analysis considers country-specific conditions and correctly predicts most of the ratification choices in countries which announced referenda (65%) and almost all parliamentary ratification cases (93%). The results reveal that governments choose referenda when they expect low gains from a treaty reform or are confronted with a Euro-sceptical parliamentary opposition. We also find that governments are eager to separate popular votes from domestic electoral campaigns.     

The Effect of Aggregation of Accounting Information via Segment Reporting on Accounting Conservatism

In a sample of U.S. multiple-segment firms, we document a negative association between aggregation via segment reporting and timely loss recognition. A higher level of aggregation, as reflected in a firm’s reported organizational structure (the definition and characteristics of its segments), causes a multiple-segment firm to exhibit less cross-segment variation in profitability than a matched control portfolio of single-segment firms. We find that firms that engage in more aggregation report accounting numbers that provide less timely information about economic losses. We also observe that firms that provide more disaggregated segment data subsequent to adopting SFAS 131 experienced an increase in timely loss recognition. This result implies that higher quality segment reporting leads to an increase in timely loss recognition, which, per extant research, is associated with better governance. Our results complement results in Berger and Hann [2003. The impact of SFAS No. 131 on information and monitoring. Journal of Accounting Research, 41, 163–223] that show a decline in inefficient internal-capital-market transfers subsequent to the adoption of SFAS 131. Overall, we provide evidence supporting Beyer, Cohen, Lys, and Walther’s [2010. The financial reporting environment: Review of the recent literature. Journal of Accounting and Economics, 50, 296–343] contention that accounting conservatism is, in part, a function of managers’ aggregation choices.     

DOES ATHLETIC SUCCESS INFLUENCE PERSISTENCE AT HIGHER EDUCATION INSTITUTIONS? NEW EVIDENCE USING PANEL DATA

This study examines the relationship between athletic success and student persistence toward a degree. We build an updated panel of National Collegiate Athletic Association (NCAA) Division I institutions and utilize within‐institution variation to identify the effects of athletic success. Using a ranking of all institutions, we find that having more successful men's basketball and football teams has a significant positive effect on first‐year retention rates. We also find some evidence that improved basketball rankings increase graduation rates, and that success in the NCAA tournament may have a sizable impact on retention. Although the estimated effects are generally modest in scale, we find rather limited evidence of other institutional factors affecting persistence, suggesting that athletics can be one avenue for institutions of higher education to engage and retain students.

Optimum government credibility in an open-economy fiscal expansion

A real open-economy model is constructed in which the government's commitment to a future fiscal expansion is not credible. Government credibility (measured by the growth rate of the probability that the expansion will occur) becomes a parameter of the system and appears directly in the eigenvalues. Simulations are performed demonstrating the effect of credibility on GNP, the exchange rate, and other variables. Lastly, the optimum credibility is determined which minimizes a loss function associated with deviations from full employment.     

Bioenergy Crop Production in the United States: Potential Quantities, Land Use Changes, and Economic Impacts on the Agricultural Sector

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops (switchgrass, hybrid poplar, and willow). At farmgate prices of US $2.44/GJ, anestimated 17 million hectares of bioenergycrops, annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually by US $6.0billion above baseline.At farmgate prices of US $1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram lands. Traditional crops prices areestimated to increase 4 to 9 percent abovebaseline prices and farm income increasesannually by US $2.8 billion above baseline.     

Embodying Embodiment in a Structural,Macroeconomic Input-Output Model

In this paper, I develop a regression-based system of labour productivity equations that account for capital-embodied technological change and I incorporate this system into IDLIFT, a structural, macroeconomic input-output model of the US economy. Builders of regression-based forecasting models have long had difficulty finding labour productivity equations that exhibit the "Solowian' property that movements in investment should cause accompanying movements in labour productivity. The production theory developed by Solow and others dictates that this causation is driven by the effect of traditional capital deepening as well as technological change embodied in capital. Lack of measurement of the latter has hampered the ability of researchers to estimate properly the productivity-investment relationship. Recent research by Wilson (2001) has alleviated this difficulty by estimating industry-level embodied technological change. In this paper, I utilize those estimates to construct capital stocks adjusted for technological change and then use these adjusted stocks to estimate Solow-type labour productivity equations. It is shown that replacing IDLIFT's former productivity equations, based on changes in output and time trends, with the new equations, results in a convergence between the dynamic behaviour of the model and that predicted by traditional (Solowian) production theory.     

Dispersed Trading and the Prevention of Market Failure: the Case of the Copenhagen Stock Exchange

With augmented demands on power grids resulting in longer and larger blackouts combined with heightened concerns of terrorist attacks, trading institutions and policy makers have widened their search for systems that avoid market failure during these disturbing events. We provide insight into this issue by examining trading behaviour at the Copenhagen Stock Exchange during a major blackout. We find that although market quality declined, markets remained functional and some price discovery occurred during the blackout period suggesting that the NOREX structure of interlinked trading systems combined with widely dispersed trading locations may be a viable means of protection against market failure during massive power disruptions or terrorist attacks.
