This research article analyses the influence of micro-enterprise (ME) managers’ perception of their relationship to their
environment on the nature of their ethics. We carried out a survey with the head managers of 125 French MEs, providing a large
set of primary data. Two types of variables were defined: (1) variables related to the nature and intensity of the relationships
between ME managers and their social environment, and (2) variables related to the ethical framework that the managers used.
The results of univariate and bivariate analyses show significant statistical relationships between the variables that indicated
perceived embeddedness in the community and ethical variables. This result underlines the idea that “communities of ethics”
may have an important influence in MEs. 相似文献

Risk is an important element in industrial adoption decisions. This paper proposes a method to investigate how different group of individuals influencing the adoption of a new industrial product differ in their assessment of the risks. Two dimensions of risk are distinguished: (1) the likelihood that adoption of the new product will have undesirable consequences, and (2) the perceived intensity of these consequences both at the organizational and at the individual level. Purchase consequences are measured in terms of product economics and product reliability. Multivariate analysis of variance is used to assess how decision participants differ in their assessment of risk components. An attempt is made to assess the relative importance of these various components in the formation of individual preferences. The implications of the analysis for the development of better industrial marketing strategies are discussed. 相似文献

We study two Durbin-Watson type tests for serial correlation of errors inregression models when observations are missing. We derive them by applying standard methods used in time series and linear models to deal with missing observations. The first test may be viewed as a regular Durbin-Watson test in the context of an extended model. We discuss appropriate adjustments that allow one to use all available bounds tables. We show that the test is locally most powerful invariant against the same alternative error distribution as the Durbin-Watson test. The second test is based on a modified Durbin-Watson statistic suggested by King (1981a) and is locally most powerful invariant against a first-order autoregressive process. 相似文献

Productive Capacity, Product Varieties, and the Elasticities Approach to the Trade Balance 总被引:1,自引:0,他引:1

Most macroeconomic models imply that faster income growth tends either to lower a country’s trade balance by raising its imports with little change to its exports or to reduce its terms of trade in order to maintain balanced trade. Krugman (1989 ) proposed a model in which countries grow by producing new varieties of goods. In his model, faster‐growing countries are able to export these new goods and maintain balanced trade without suffering any deterioration in their terms of trade. This paper analyzes the growth of US imports from different source countries and finds strong support for Krugman’s model. 相似文献

This paper exploits the unique experimental setting created by nearly 1,300 new single stock futures listings on the OneChicago exchange between 2003 and 2009. I investigate the impact of derivatives introductions on the tightness of short sale constraints facing their underlying assets. After controlling explicitly for supply and demand conditions in the stock lending market, this experiment reveals a precipitous decline in active utilization rates and loan fees in the lending market, after the futures introductions. The paper provides strong evidence that supports the view that derivatives represent a viable alternate synthetic short selling venue relaxing short sale constraints facing their underlying assets. 相似文献

We measure arbitrage opportunities by comparing the intraday prices and quotes of American Depositary Receipts (ADRs) and other types of cross-listed shares in U.S. markets with synchronous prices of their home-market shares on a currency-adjusted basis for a sample of 506 U.S. cross-listed stocks from 35 different countries. Deviations from price parity average an economically small 4.9 basis points, but they are volatile and can reach large extremes. Price parity deviations and their daily changes are positively related to proxies for holding costs that can impede arbitrage, even after controlling for transactions costs and foreign investment restrictions. 相似文献

We consider the problem of testing whether the observations X1,…,Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed: exponential bounds, Eaton-type bounds, Chebyshev bounds and Berry–Esséen–Zolotarev bounds. The bounds are exact in finite samples, distribution-free and easy to compute. The performance of the bounds is evaluated and compared with traditional serial dependence tests in a simulation experiment. The procedures proposed are applied to U.S. data on interest rates (commercial paper rate). 相似文献

The impact of international trade on labour markets in developed countries will be different according to the degree of competition in product markets, the flexibility of the labour market and the skill intensity of production. An econometric analysis of the impact of trade in France has been undertaken using sectoral data for the period 1985–p1992. It is found that lower relative import prices reduce the relative employment of low skill workers in the first half the period and reduce their relative wages in the second half. In both cases the effect is more pronounced in sectors where the skill intensity of production is initially low. 相似文献

Social security, retirement age and optimal income taxation 总被引:1,自引:0,他引:1
It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that, when first-best redistributive instruments are not available, because some variables are not observable, the optimal policy does imply a distortion of the retirement decision. Consequently, the inducement of early retirement may be part of the optimal tax-transfer policy. We consider a model in which individuals differ in their productivity and their capacity to work long and choose both their weekly labor supply and their age of retirement. We characterize the optimal non-linear tax-transfer that maximizes a utilitarian welfare function when weekly earnings and the length of active life are observable while individuals' productivity and health status are not observable. 相似文献
