We quantify the impacts of droughts in New Zealand on the profitability of dairy, sheep and beef farms using a comprehensive administrative database of all farms in New Zealand. For dairy farms, we found that drought events have positive impacts on dairy farms’ revenue and profit in the year of the drought. This effect is most likely attributable to drought‐induced increases in the export price of milk solids, as New Zealand is the market maker in this global market and almost all domestic dairy production is exported. All of these quantified impacts, however, are not very large, suggesting that, at this point in time, droughts have a fairly moderate impact on New Zealand dairy and sheep–beef businesses.  相似文献

This paper studies irreversible investment in the presence of uncertain revenue and uncertain cost of production. Using methodology of real options, we find the threshold markup of price over cost that triggers investment. When the processes for revenue and cost are negatively correlated, the standard result that uncertainty delays investment always holds. However, when these two processes are positively correlated, greater uncertainty of revenue or cost might accelerate investment. As less correlated cost and revenue, vertical FDI is less desirable than producing at home, but horizontal FDI that brings production to the output market is an advantage.  相似文献

There is a widely held notion that as production costs decline with experience, prices should follow more or less in parallel. Although this notion has been an important factor in estimating experience curves and in formulating corporate strategies, we show that it is generally inconsistent with published multiperiod optimal pricing models. The paper then goes on to demonstrate that this apparent conflict can be reconciled by allowing the demand process to exhibit increasing price elasticity over time. Since this demand characteristic is very plausible for innovative products, we suggest it be incorporated into optimal pricing models.  相似文献

In the following study the process of microcomputer adoption and diffusion at an academic institute is described and the implications of this innovation for faculty and students are assessed. The individual acquisition data are analyzed using the Mansfield diffusion model. In addition, I report a case study describing the centralized purchase decision-making process at the institute, and conclude with a longitudinal empirical study that examines the development of microcomputer uses and users' attitudes over a period of 1 year. The results show mainly that the adoption process is quite slow, although the response of the users is generally found to be quite favorable.  相似文献

This paper examines strategic trade and joint welfare maximizing incentives towards investment in the quality of exports by an LDC and a developed country. Firms first compete in qualities and then export to an imperfectly competitive, third country market. Under Bertrand competition, unilateral policy involves an investment subsidy by the low-quality LDC and an investment tax by the developed country, whereas jointly optimal policy calls for the reverse so as to reduce price competition by increasing product differentiation. Under Cournot competition, unilateral policy is also reversed from the Bertrand outcome, but jointly optimal policy involves a tax in both countries.  相似文献

The potentially adverse effects of droughts on agricultural output are obvious. Currently, Indonesian rice farmers have little financial protection from climate risk via catastrophic weather risk transfer tools. Done well, a weather index insurance (WII) program can not only provide resources that enable recovery, but can also facilitate the adoption of prevention and adaptation measures and incentivize risk reduction. However, implementations of WII programs have faced difficulties because of basis risk—among several other obstacles. Here, we quantify the applicability, viability, and likely cost of introducing a WII for droughts for rice production in Indonesia. To reduce basis risk, we construct district-specific indices that are based on the estimation of Panel Geographically Weighted Regressions models. With these spatial models, and detailed district level data on past agricultural productivity and weather conditions, we identify an algorithm that can generate an effective and actuarially sound WII in some districts but not in others. We then measure its effectiveness in reducing income volatility for farmers by reducing this basis risk, at the district level. We end by calculating an actuarially robust and welfare-enhancing price for this scheme and prioritize the districts in which it can be implemented.  相似文献

Endogenous Financial and Trade Openness   总被引:2,自引:0,他引:2  
The authors study the endogenous determination of financial and trade openness. They construct a theoretical framework leading to two-way feedbacks between financial and trade openness and identify these feedbacks empirically. They find that one standard deviation increase in commercial openness is associated with a 9.5% increase in de facto financial openness (% of GDP). Similarly, an increase in de facto financial openness has powerful effects on future trade openness. De jure restrictions on capital mobility have only a weak impact on de facto financial openness, while de jure restrictions on the current account have a large adverse effect on commercial openness. The authors investigate the relative magnitudes of these directions of causality using Geweke's (1982 ) decomposition methodology. They conclude that in an era of rapidly growing trade integration, countries cannot choose financial openness independently of their degree of openness to trade. Dealing with greater exposure to turbulence by imposing restrictions on financial flows is likely to be ineffectual.  相似文献

This study posits that a local process of creative destruction provides an impetus to regional industrial renewal. We argue that exits of older firms release resources that stimulate local entry. New entrants add value to these resources by redeploying them in more productive uses. We test our hypotheses with a unique longitudinal database encompassing the entry and exit of Canadian manufacturing enterprises. We find that exits of old firms increase entry and that on average new entrants are more productive. Persistent high local rates of exit, however, deter entry.  相似文献

This study estimates the causal effect of the 2004 Indian Ocean tsunami on household consumption and income in Sri Lanka 8 years after the event, using a difference‐in‐differences methodology and extensive household survey data. The analysis finds a strong association between the area‐wide tsunami disaster shock and increases in household income and consumption in the long term. The increase in consumption is much smaller than the observed increase in income; while the increase in income is mostly observed in nonagricultural wage income (and a decline in agricultural income). We also find that households in high‐income regions and lower‐damage districts experienced a much better recovery, in terms of income, than those in poorer regions or those districts that experienced more destruction. Deviating from the common observation on short‐term adverse impacts of catastrophic disasters in low‐ and middle‐income countries, these results are suggestive of a potential for long‐lasting and more successful recovery scenarios. Still, Sri Lanka received a very large amount of external assistance post‐tsunami—an amount that may not be replicable elsewhere. It is likely that this massive inflow of assistance, further helped by the end of the armed conflict in 2009, has contributed significantly to this relatively successful recovery.  相似文献
