A sequential investment is a vector of payments over time, ( a 0 , a 1 , ... , an ), where a payment is made to or by the investor according as ai is positive or negative. Given a collection of such investments it may be possible to assemble a portfolio from which an investor can get \"something for nothing,\" meaning that without investing any money of his own he can receive a positive return after some finite number of time periods. Cantor and Lipmann (1995) have given a simple necessary and sufficient condition for a set of investments to have this property. We present a short proof of this result. If arbitrage is not possible, our result leads to a simple derivation of the expression for the long–run growth rate of the set of investments in terms of its \"internal rate of return.\" 相似文献

While public construction in Israel is of a magnitude sufficient to exert effective housing market countercyclical influence, it has often had the opposite effect. This phenomenon is viewed with particular concern, given that economywide recessions of past decades have been precipitated by significant downturns in the construction industry. This paper describes specification and estimation of a simultaneous-equation structural model of the Israeli housing market. Results of the analysis indicate the importance of disaggregation by public and private sectors as well as the significance of mortgage availability and price, substitution and income effects, disruptions caused by war and the like in an explanation of cyclical phenomenon. 相似文献

The article uses trade data between China and ASEAN countries to test hypotheses related to pricing to market (PTM) and consequent local currency price stability (LCPS). The degree of price discrimination associated with real RMB exchange rate changes between China and ASEAN + 2 shows evidence of local currency price stability in some industries in which exporters may be less competitive. China's trade policy may have also played a role in the local currency price stability. The article finds no evidence that RMB appreciation creates a larger impact on price adjustment than RMB depreciation. 相似文献

This study explores differences in the perceptions of fairness between two employee evaluation methods: one based on data
collected using the mystery customer method and the other based on supervisor judgment. Fifty eight female sales clerks filled
out a questionnaire which assessed their perceptions with respect to the fairness of the two evaluation methods and their
job satisfaction. Given apparent differences in the evaluating agent, the extent of process consistency, the breadth of behaviors
evaluated, and the extent of employees' awareness of the evaluation process, we hypothesize and find that evaluation procedures
conducted by supervisors are perceived as more fair both procedurally and distributively than those conducted by means of
the mystery customer method.The expected relationship between perception of fairness and job satisfaction was, however, foundonly
in the correlations with supervisor evaluations and not in the correlations with the mystery customer evaluation method. Though
the results are limited by the restricted sample, they shed an important light on the perceived fairness of the mystery customer
procedure, and suggest that the choice of this procedure should take into account the fairness aspect of it when assessing
its effectiveness and value.
The data in this study was collected by Idit Malka and Michal Ben-Avi, for a research seminar conducted under the supervision
of the second author. 相似文献

This study examines how Chinese firms began responding to worsening environmental concerns in the late 1990s. Combining predictions from control theory, escalation of commitment, and goal theory, we seek to explain how leaders' cognitions shape the formation of novel responses to the value‐laden issue of corporate greening. We propose an iterative model that links leaders' principles with corporate actions and test it using survey data gathered from 360 firms. The model views strategy organically, as a set of adaptive goals and behaviors, and highlights the role of systemic and local feedback loops in strategy formation. We find that top executives who champion new strategic initiatives monitor early success or failure, and adjust their efforts to match early performance feedback. Perceptions of satisfactory performance strengthen leaders' efforts towards their initial target, while perceptions of unsatisfactory performance diminish them. This feedback relationship is invariant throughout favorable or unfavorable expectancies of success, contrary to the contingent prediction of control theory. The model also examines how top‐down and bottom‐up strategic initiatives combine to help firms maintain a positive momentum of change when champions' efforts decline in the face of premature failure signals.

The research examines the two paths of influence of activation technique in advertising, defined as engaging in motor activity required to reveal the advertising message. Under the first path, activation technique enhances the perceived creativity of the advertisement, via its structural and design aspects; whereas under the second path it influences processing fluency via its compatibility with the message. In the latter, activation technique may detract from overall evaluations of the advertisement, especially when the motor activity is incompatible with the message. Two experimental designs demonstrate this dual effect and its underlying mechanism. 相似文献

We analyze the evolution of foreign direct investment (FDI) inflows to developing and emerging countries around financial crises. We empirically examine the Fire‐Sale FDI hypothesis and describe the pattern of FDI inflows surrounding financial crises. We also add a more granular detail about the types of financial crises and their potentially differential effects on FDI. We distinguish between mergers and acquisitions (M&A) and greenfield investment, as well as between horizontal (tariff jumping) and vertical (integrating production stages) FDI. We find that financial crises have a strong negative effect on inward FDI in our sample. Crises are also shown to reduce the value of horizontal and vertical FDI. We do not find empirical evidence of fire‐sale FDI; on the contrary, financial crises are shown to affect FDI flows and M&A activity negatively. 相似文献
