We present a model of a risk-averse exporting firm subject to liquidity constraints. We show that preferences and expectations become important for optimum export and hedging decisions. Only firms that have sufficient financial resources can fully materialize gains from trade. 相似文献

Invasive animal pests reduce crop and livestock output, require management and control measures, and threaten native plants,
animals and their habitat. The agricultural and management costs are often directly measurable. But the costs to protect threatened
native plants and animals are harder to assess. The Rural Lands Protection Boards were the government agency in New South
Wales that managed invasive animals. An analysis of their decisions provided the opportunity to estimate the costs of protecting
native species. The number of native plants and animals threatened by invasive pests was modelled against the expenditure,
area, pest abundance, climate and location of 38 Board districts. There was a strong negative relationship between the number
of threatened native species and Board expenditure. This relationship was interpreted to estimate the marginal cost of protecting
a threatened native species, the downward shift in the supply curve necessary to protect all threatened native species, and
the gains from the shift in the form of cost savings in the continued protection of non-threatened native species. These results
value some of the costs that invasive animal pests impose on the environment. 相似文献

The effect of real rates of interest on housing prices 总被引:7,自引:0,他引:7
Jack C. Harris 《The Journal of Real Estate Finance and Economics》1989,2(1):47-60
During the late 1970s, U.S. house prices were appreciating rapidly even though mortgage interest rates were climbing. Recently, interest rates have eased but prices have moderated. This study examines the role of appreciation expectations in overcoming the negative effects of nominal mortgage interest rates on house prices. Expectations of future appreciation are important determinants of house sales prices, remaining influential during periods of declining and moderating real prices, not just when prices are rising. The real rate of interest, as viewed by the homebuyer, is the mechanism for affecting change in housing price levels. Because the nominal interest rate is slow to reflect changes in expectations, these real rates vary over time. This ebb and flow of real interest rates appears to explain market price levels. Nominal rates play a role as well, primarily in the formation of appreciation expectations. 相似文献

In this paper, the authors empirically examine whether corporations with high degrees of insider ownership enjoy superior returns compared with firms with more diffuse ownership. In addition, the authors evaluate the effects of insider ownership on security returns in relations to the well-known effects of size and earnings yield (or price-earnings) ratios. Results indicate that, in addition to Basu's price-earnings effect, insider ownership is a new statistically significant variable that is associated with abnormal returns. This return anomaly might occur because the market pays an inadequate price for top managements' equity ownership, a firm-specific fundamental variable that has a theoretical foundation in agency theory. 相似文献

The basis between a futures contract and its underlying instrument is an important measure of the cost of using the futures contract to hedge. In a cross-hedge, the relative size of the basis of alternative hedging vehicles often plays a decisive role in the selection of the optimal hedging vehicle. After adjusting hedge ratios for basis risk, a genuine risk-cost trade-off is seen in hedging 90-day certificates of deposit with either the Treasury bill contract or the Eurodollar contract. The Eurodollar contract was not uniformly superior as generally believed. 相似文献
