This paper investigates how a development moratorium affects choices of development timing and land values in a framework where both the value of developed property evolves stochastically and the development costs are fully irreversible. We assume that a regulator initially announces that land is not allowed to be developed during a finite period of time in the future. A developer, thus, must decide whether to develop land before the timing ordinance is imposed, or after it expires. The development moratorium reduces the developer’s option value from waiting and, thus, accelerates development. We also use simulation analysis to demonstrate how the other factors that relate to the demand and supply conditions of the real estate market affect this accelerating effect.  相似文献

This paper focuses on the sources of intra‐industry price variability in US food industries during a period of increasing concentration, while accounting for the impact of variations in prices of primary agricultural products. Results suggest that intra‐industry price variability in food industries increases with their respective mean rate of inflation and product heterogeneity. However, industrial concentration lowers the sensitivity of relative prices to changes in the mean rate of inflation. Hence, static welfare losses to consumers from increasing concentration in food industries, a subject of recent and intensive investigation, can partly be offset by gains such as reduced price variability.  相似文献

Real Investment Implications of Employee Stock Option Exercises   总被引:6,自引:0,他引:6  
This paper examines a real cost of awarding employee stock options. Based on the observation that managers are extremely concerned about earnings-per-share dilution in equity related compensation, we predict and find that firms experiencing significant employee stock option (ESO) exercises shift resources away from real investments towards the repurchase of their own stocks. We further find weak evidence of a decline in subsequent firm performance (as measured by return on assets) for several years following the cut in discretionary investments as a result of stock option exercises, though this result is sensitive to the metric used to measure performance. Collectively, our findings indicate that ESO exercises potentially impose a real cost on the firm in terms of foregone investment opportunities.  相似文献

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.  相似文献

Mutual Fund Advisory Contracts: An Empirical Investigation   总被引:3,自引:0,他引:3  
We investigate marginal compensation rates in mutual fund advisory contracts and find the following. Equity and foreign fund advisors receive higher marginal compensation than debt and domestic fund advisors. Advisors of funds with greater turnover receive higher marginal compensation. Also, closed-end fund advisors receive higher marginal compensation than open-end fund advisors. Finally, we find that marginal compensation is lower for advisors of large funds and members of large fund families. We argue that these differences in marginal compensation reflect differences in advisor marginal product, differences in the difficulty of monitoring performance, differences in control environments, and scale economies.  相似文献

This paper examines the negative externality imposed by a direct marketing firm on the consumers who must spend time reading and processing the advertising they receive from that firm. A model is developed to show that with low communication costs, a firm would send out more unsolicited advertising messages than would be desired by consumers and a social welfaremaximizing planner. The optimal Pigovian tax to eliminate the problem of excessive message sending is then derived. The extent of the problem in a number of media, including direct mail, telemarketing, and the Internet, is briefly examined.  相似文献

An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms.  相似文献

This paper addresses Ravi Batra’s (2002 ) criticism of the basic comparative advantage gains‐from‐trade model. While Batra’s criticism is based on the selection view interpretation of real income, the gains from trade can only be properly understood from the options view interpretation of real income. I also show how a recent empirical implementation of the gains‐from‐trade model defies Batra’s claim that “the consumption gain . . . is not subject to measurement” (2002, p. 642).  相似文献
