This paper simulates forward hedging of foreign exchange risks for U.S. investments in U.K., German and French equities. Rolling OLS and SUR regressions are used to obtain monthly exposure coefficients (hedge ratios), and the micro-market mechanics of the exchange rate bid-ask spread are considered throughout. While the coefficient of variation favors not hedging, no statistically significant differences are found between no hedge and hedge strategies. However, hedging produces a nontrivial incidence of cases where liquidated foreign equity values are less than amounts sold forward. The results, robust to rising and falling dollar sub-periods, do not support forward hedging.  相似文献

This paper extends the standard model of urban land rent to consider the impact of the output of public programs on the spatial equilibrium and to analyze the accuracy of changes of urban land values as a measure of social benefits from public investment. Two consistent output indicators of public investment are advanced: the individual's welfare and total land values. The general results of the comparative analysis are that there is a lack of correspondence between both output indicators, and that changes in land values are, in general, not an accurate measure of the benefits of such programs.  相似文献

This article investigates, through the country-of-origin effect and value-in-use lenses, how the implementation of digital services creates opportunities for cultural industries to expand internationally. We argue that intrinsic attributes of cultural content such as the capacity to entertain are difficult to parameterize because they are somewhat experiential and subjective. This means that extrinsic cues are essential to foreign consumers when making a decision to purchase digital services. We specifically evaluate the influence of Britishness, cultural distance, exoticness, brand image, and flag-brand congruence on the purchase intentions of consumers in foreign markets. This study employs a unique consumer dataset with information on the internationalization of British cultural digital services. The depth and breadth of the survey data collected through collaboration with a UK media industry partner with a globally recognised brand is significantly richer than data used in previous studies. In particular, the study exploits a survey with 5,200 usable data points from consumers residing in fourteen geographically dispersed countries. Findings support theoretical predictions that Britishness, cultural distance, exoticness, brand image and flag-brand congruence are positively linked to the purchasing decisions. Theoretical and managerial implications are discussed.  相似文献

Over the past two decades, world olive oil consumption registered an impressive growth. Although olive oil consumption remains concentrated in the main producer countries surrounding the Mediterranean Sea (“traditional” markets), it is also growing rapidly in many other countries all over the world, where olive oil is still largely perceived as a novelty food (“nontraditional” markets). This study focuses on the Brazilian market of olive oil, which is one of the most important nontraditional markets in terms of both its dimension and growth rates. A hedonic price model has been used to evaluate whether, and to what extent, extrinsic cues impact on the retail price of olive oil. Data were collected via direct observation of several e-shops where Brazilian consumers could purchase olive oil. Results show that the retail price of olive oil is highly influenced by extrinsic cues such as branding, labeling, and packaging.  相似文献

We analyse the estate composition of the richest 30 per cent of people who died in the Netherlands in 1921 to find that households used a broad range of institutions to meet their financial demands. Goods and services were either paid in cash or settled periodically with suppliers. Despite the strong growth of commercial banking in the previous decades, households still made extensive use of peer-to-peer loans, with or without the added security of notarial contracts. Banks only possessed a competitive edge in savings accounts for small surpluses and current accounts, the latter used most frequently by business owners born after 1870. Distance to the nearest bank office did not matter for these people, but wealthy urbanites were more inclined to use banks than their counterparts in the countryside.  相似文献

In this paper, I estimate the effect of future pension benefits on pre-retirement labor supply for a representative sample of Chilean workers. Using nonlinear patterns in pension benefit formulas and a reform that permanently changed non-contributory pensions, I estimate the effect of pension accrual and expected pension wealth on labor force and contributory-sector participation, labor earnings, and hours worked. I find that the effect is concentrated on the impact of pension accrual on the probability to contribute to the pension system. The effect is heterogeneous and is concentrated among middle-aged workers, low-skilled workers, and workers with higher financial literacy.  相似文献

This paper aims to compare the performance of three different artificial neural network techniques for tourist demand forecasting: a multi‐layer perceptron, a radial basis function and an Elman network. We find that multi‐layer perceptron and radial basis function models outperform Elman networks. We repeated the experiment assuming different topologies regarding the number of lags used for concatenation so as to evaluate the effect of the memory on the forecasting results. We find that for higher memories, the forecasting performance obtained for longer horizons improves, suggesting the importance of increasing the dimensionality for long‐term forecasting.
