Conclusion The article provides a contribution to the discussion on the net foreign assets of the commerical banks, by drawing renewed attention to the possible passivity of the banking sector, which has gained topicality with the striking developments of 1989. Indeed, the banking sector may be considerably more reactive in regards to net foreign assets formation than has been assumed by various authors and in macroeconometric models on the basis of portfolio optimizing behaviour. However, due to the above-mentioned methodological and empirical shortcomings, Bakkers's study certainly does not provide the final answer to this question.  相似文献

Nelson and Plosser (1982), in a classic paper, failed to find strong evidence against the null hypothesis of a generating process with a unit autoregressive root for thirteen US macroeconomic time series. Perron (1989) claimed that such evidence was available for a majority of these series if the alternative hypothesis was of trend stationarity with a break in 1929. Zivot and Andrews (1992) treated the break date as endogenous, then finding strong evidence agcainst the null for a minority of these series. Our own analysis extends theirs by permitting a break under the null as well as the alternative hypothesis, and allowing for the sequential nature of the testing. Our empirical findings complete the circle. We find no strong evidence against the unit root hypothesis for any of the thirteen Nelson–Plosser series.  相似文献

Employment Contacts and Minority-White Wage Differences   总被引:1,自引:0,他引:1  
We study effects of job contacts on wages in inner-city Boston in 1989 and in the 1982 NLSY. Race/Hispanicity differences in wages are not explained by an absence of contacts among minority youths. Rather, in the Boston data, lower wages of black youths are explained by lower "returns" to their contacts. In the NLSY there is little evidence of lower return to black youths' contacts, but there is evidence of lower returns to Hispanic youths' contacts.  相似文献

Large Non-Union Companies: How Do They Avoid a Catch 22?   总被引:1,自引:0,他引:1  
Large non-union companies might be expected to enjoy extensive work-force flexibility deriving from their high-wage, high-involvement strategies. However, where there is a strong local union presence, this might be expected to exert a strong dampening effect on the levels of internal flexibility achieved. Such companies, fearful of union organization, could not then enjoy the freedoms that might be associated with a non-union strategy. Research conducted in the Republic of Ireland on large non-union US companies operating in the electronics industry suggests a conceptual framework indicating how a Catch-22 situation is avoided in these companies.  相似文献

The purpose of this article is to study the level of “in‐stock” customer service performance being offered in the catalog channel of distribution. The article provides benchmark information for the catalog industry. More importantly, the article serves as one test of the effectiveness of the modern supply chain, where the expectation is for near perfect orders. Customer service levels are studied by using an empirical observation methodology in which catalog retailer's in‐stock performance was measured. Comparisons are made across item type, season, retailer type, and days from catalog receipt. Overall, items were out‐of‐stock during 15.9% of all checkpoints, compared to an 11.8% stock‐out rate in an earlier study of bricks and mortar retailers.  相似文献
