This paper develops a spatial merger estimator to explain political integration generally and then applies this method to a wave of school district mergers in the state of Iowa during the 1990s. Our estimator is rooted in the economics of matching and thus accounts for three important features of typical merger protocol: two-sided decision making, multiple potential partners, and spatial interdependence. Rather than simply explaining when a particular region is likely to experience a wave of political integration, our method allows us to explore the factors driving which specific subregional mergers take place. This allows us to explore how those districts that merge choose with which of their neighbors to do so. Our results highlight the importance of state financial incentives for consolidation, economies of scale, diseconomies of scale, and a variety of heterogeneity measures in this particular application. We also demonstrate the power of our estimator, relative to existing estimators, to detect a statistically significant role for heterogeneity factors. While our application is limited to school district consolidation, our method can be adapted to include the salient features of many spatial integration problems. 相似文献

We examine the long‐run stock price and operating performance of companies that withdraw seasoned equity offerings (SEOs). Firms that withdraw an offering provide an opportunity to examine whether markets fully adjust to the information conveyed when managers announce the intent to issue shares, independent of any agency problems that might be intensified by the completion of the offering. As in completed seasoned equity offerings, long‐horizon event‐time operating and stock price performance in sample firms is substantially lower than what is observed among control firms. Underperformance is also observed in an equally weighted calendar‐time analysis. Results are consistent with overpricing among small firms that attempt, but then withdraw, SEOs. 相似文献

To date, the majority of studies on job satisfaction use either a global measure or the JDI measure. To extend current research, this study uses the seven dimensions of job satisfaction as described by Churchill et al. [Churchill, G.A., Ford, N.M., Walker, O.C. Measuring the job satisfaction of industrial salesmen. J Mark Res 1974; 11 (3): 254-260.] to explore the relationship between job satisfaction, emotional exhaustion, organizational commitment and propensity to leave. Findings suggest that: 1) emotional exhaustion only relates to certain dimensions of job satisfaction and 2) job satisfaction dimensions related to organizational commitment and propensity to leave are not necessarily the same. Overall, this research provides an argument for the use of the seven dimension job satisfaction scale, as opposed to global measures or the JDI measure. 相似文献

This edited volume makes a large and welcome contribution toour understanding of the history of entrepreneurial financein the United States. The focus of the volume is on innovationby both corporations and entrepreneurs. It examines all theimportant forms of financing, including wealthy individuals(who we now call angels), venture capital, government financingand debt. Scholars of many disciplines, including economics,finance, entrepreneurship, business history, and organizationalnetworks will find this volume to be of interest and the essayscan be read either selectively or globally. Lamoreaux and Sokoloff's introduction is a significant chapterin itself, providing a rich historical analysis of the riseof the U.S. patenting system. The editors also provide a 相似文献

Data collected from interviews with new landowners in KwaZulu-Natal in 1999 show that households on four government-assisted projects had less tenure security than households that acquired land via private transactions. Households in government-assisted projects also used less agricultural credit and had less liquidity and less wealth. The probability of households using agricultural credit increased with more secure tenure, more household wealth (number of durable goods), higher liquidity and higher levels of household education. It is recommended that more emphasis be placed on redistributing land through the private market and encouraging the creation of management committees or joint enterprises to utilise the land settled by large groups of beneficiaries. This would be a first step towards making tenure more secure, most notably in the government land reform projects. More secure tenure would improve the creditworthiness of emerging farmers, thereby creating incentives for investing in improvements and complementary inputs to raise agricultural performance. 相似文献

Survival analysis is used to estimate time‐varying probabilities of price reversals using daily data for the Australian All Ordinaries Price Index. Lagged price changes lead to persistence (shortening) in a price run if they are of the same (opposite) sign as the run. An increase in the number of runs observed in the previous 30 days also increases the probability of price reversal. The predictive accuracy of the models is assessed using a probability scoring rule. Consistent with market efficiency, the estimated models are less accurate than the random walk model in predicting the length of individual price runs out‐of‐sample. 相似文献

We add health and longevity to a standard model of life‐cycle saving and show that, under plausible assumptions, increases in life expectancy lead to higher savings rates at every age, even when retirement is endogenous. In a stationary population these higher savings rates are offset by increased old age dependency, but during the disequilibrium phase, when longevity is rising, the effect on aggregate savings rates can be substantial. We find empirical support for this effect using a cross‐country panel of national savings rates. 相似文献
