“Good Cause Beliefs” in an “At-Will World”? A Focused Investigation of Psychological Versus Legal Contracts

This study assesses the psychological contracts of a group of at-will employees and compares their relevant psychological contract beliefs with the terms of the controlling legal employment contract. In addition, we test specific hypotheses regarding the relationship between employers formal job security policy (employment at-will vs. good cause protection, and employee personal characteristics; equity sensitivity, organizational tenure) to 2 focal psychological contract beliefs (the employers obligation to have a good reason to discharge the employee, and the employees reciprocal obligation to have a good reason to leave his/her employer). These issues are investigated using survey data sampled from 15 diverse U.S. organizations, and independently collected information regarding organizations job security policies. The results provide evidence of a widely shared psychological contract belief that, despite explicit at-will policies, U.S. employers are highly obligated to have a good reason to discharge employees. Further, personal characteristics are more strongly related to the focal psychological contract beliefs than employer job security policies. The theoretical contribution of the study and its practical implications are discussed.     

The transition from central planning to a market economy: A computable general equilibrium model

This paper develops a computable general equilibrium (CGE) model of the transition from a central planned economy to a market economy. The model is an extension of Wellisz and Findlay's (1986) model of the Soviet second economy. By distinguishing alternative assumptions about the disposition of the government budget, two model variants — the activist and non-activist — are analyzed. Equilibria of these model variants are computed for various parameter specifications of the Kantorovich ray, which represents the stringency of central planners' direction of the economy. The paper shows that increasing efficiency of the private sector, while it reduces the size of government subsidies to the state sector, does not necessarily increase the net government budget.     

Up-front payment under RD rule

This paper explores the effect of an up-front payment to contracts under the reliance damage measure. We find that the efficiency in most cases fails, but can be obtained by a high enough total payment to assume away the sellers breach, a high enough up-front payment to ensure that the seller does not sue, and a high enough trading price to ensure the buyers breach when the undesirable state occurs. Edlins device (1996), which has a very low trading price to assume away the buyers breach and a proper up-front payment to entice the seller to sign, fails to achieve the efficiency under the reliance damage measure.Received: 1 May 2002, Accepted: 15 May 2004, JEL Classification: K12, L00, D21Ho-Chyuan Chen: I wish to thank an anonymous referee of this journal for valuable comments.     

Dictatorial voting operators

Voting operators map n-tuples of subsets of a given set X of candidates (the voters choices) into subsets of X (the social choice). This paper characterizes dictatorial voting operators by means of three conditions (the non-emptiness condition A1, the independence condition A2 and the resoluteness condition A3) motivated by the idea of transferring to the social choice properties common to all the voters choices. The result is used to refine Lahiris (2001) characterization and to derive dictatorial results in other three types of aggregation problems, in which choice functions are transformed into choice functions, binary relations into choices and binary relations into binary relations.Received: 20 May 2002, Accepted: 5 August 2003, JEL Classification: D70, D71Antonio Quesada: Present address: Departament dEconomia, Facultat de Ciéncies Económiques i Empresarials, Universitat Rovira i Virgili, Avinguda de la Universitat 1, 43204 Reus (Tarragona), Spain.

Kusterer or Manwaring and Wood on the High-Tech Labor Process? Analyzing the Nature of Skill,Deskilling and Managerial Control of Labor in a U.S. Medical Electronics Factory

Since Bravermans (1974) work revived interest and research in labor process theory, labor process theorists have developed differing conceptions of the nature of skill, deskilling and the managerial control of labor in the capitalist work organization. In this article, I examine two labor process theories, K. Kusterers (1978) theory of working knowledge and Manwaring and Woods (1985) theory of tacit skills, with regards to the nature of skill, deskilling and the managerial control of labor and test these two theories with respect to data obtained on unskilled and semiskilled production work at a high-tech medical electronics factory. I conclude that there is more support for Manwaring and Woods (1985) theory of tacit skills than for Kusterers (1978) theory of working knowledge for high-tech production work.     

A note on randomized response models for quantitative data

Standard randomized response (RR) models deal primarily with surveys which usually require a yes or a no response to a sensitive question, or a choice for responses from a set of nominal categories. As opposed to that, Eichhorn and Hayre (1983) have considered survey models involving a quantitative response variable and proposed an RR technique for it. Such models are very useful in studies involving a measured response variable which is highly sensitive in its nature. Eichhorn and Hayre obtained an unbiased estimate for the expectation of the quantitative response variable of interest. In this note we propose a procedure which uses a design parameter (controlled by the experimenter) that generalizes Eichhorn and Hayres results. Such a procedure yields an estimate for the desired expectation which has a uniformly smaller variance.Acknowledgements We are grateful to two referees for their valuable and constructive comments.     

Technical Inefficiency Effects Among Paddy Farmers in the Villages of the ‘Office du Niger’, Mali,West Africa

A stochastic frontier production function incorporating a model for technical inefficiency effects (Battese and Coelli, 1995) is applied to field data on paddy farmers from 29 villages in the Office du Niger in Mali. Four conventional factors (land, labor, fertilizer and machinery) are considered as inputs of production. The technical inefficiency effects in the stochastic frontier were related to firm-specific variables, institutional factors, social organisation, ecological considerations and health factors. Data were obtained from an economic survey conducted during two consecutive agricultural seasons (1989 and 1990) on 844 farms of the Office du Niger. The null hypothesis of the absence of technical inefficiency effects was rejected. A supportive institutional environment and a coherent organisation of land use were the best correlates of technically efficiency. The social environment was also found to contribute to technical efficiency of the paddy farmers: within the village, the greater the degree of ethnic cohesion, the greater the efficiency of the farmers. Health status of households had an effect in that healthy families tended to be more technically efficient than unhealthy ones. Farmers with more extensive sorghum cultivation were less efficient as paddy farmers. These results may help agricultural policy makers formulate strategies. Technical efficiency may be improved by intensifying agricultural training regarding one specific crop and, through the control of parasitic diseases which place a burden on family households.     

Economic planning and information

Conclusions The central arguments for national planning put forward during the early part of this century were decisively refuted by Mises and Hayek during the 1920s and 30s (see Hayek, 1948). General equilibrium theory of the 1960s provides no more adequate justification for the version of indicative planning proposed in this article. It is disappointing to see that no account has been taken of the important recent developments in economic theory and analysis which provide a more realistic basis on which to compare the private market and government agencies.There is no doubt that the country's future growth and development depend upon identifying more profitable investiment opportunities in the British economy (p. 140). There is equally no doubt that an infinite number of such opportunities exist. But how to identify them? Regrettably, Paul Hare does not tell us.     

A two-stage stratified Warner’s randomized response model using optimal allocation

This paper applies Kim and Wardes (2004) stratified Warners randomized response model to Mangat and Singhs (1990) two-stage randomized response model. The proposed stratified randomized response model has an optimal allocation and a large gain in precision. Hence, the estimator based on the proposed method is more efficient than Kim and Wardes (2004) and Mangat and Singhs (1990) estimators under the conditions presented in both the case of completely truthful reporting and that of not completely truthful reporting by the respondents.     

Exponential convergence properties of linear estimators under exponential and uniform distribution

Summary Certain measures of asymptotic efficiency of test statistics are based on exponential convergence properties of the underlying error probabilities (Bahadur-, Hodges-Lehmann-efficiency). From a general large deviation theorem, that is specified to weighted sums of independent identically distributed (i.i.d.) random variables, such exponential convergence properties are derived for test statistics which are linear functions of order statistics of i.i.d. random variables under exponential and uniform distribution. For that purpose some smoothness-conditions for the weights have to be established. In a series of examples it is shown that these conditions are fulfilled for certain robust linear estimators of location or scale parameters. With the help of some numerical results two of them, namely Winsorized and trimmed mean, are compared with regard to the asymptotic relative efficiency against each other.

Zusammenfassung Bestimmte asymptotische Effizienzbegriffe für Tests basieren auf einem exponentiellen Konvergenzverhalten der zugrundeliegenden Fehlerwahrscheinlichkeiten (Bahadur-, Hodges-Lehmann-Effizienz). Mit Hilfe eines allgemeinen Satzes üver Wahrscheinlichkeiten großer Abweichungen, der spezialisiert wird auf gewichtete Summen unabhängiger, identisch verteilter (i.i.d.) Zufallsvariablen mit momenterzeugenden Funktionen, wird ein solches exponentielles Konvergenzverhalten nachgewiesen für Linearkombinationen von order statistics von i.i.d. Zufallsvariablen unter Exponential- und Rechteckverteilung. Dazu sind bestimmte Bedingungen an die Gewichte zu stellen. In einigen Beispielen wird gezeigt, daß solche Gewichtsbedingungen für eine Reihe von robusten Schätzern erfüllt sind. Zwei spezielle, nämlich das Winsorisierte und getrimmte Mittel, werden mit Hilfe einiger numerischer Ergebnisse hinsichtlich ihrer asymptotischen Effizienz miteinander verglichen.

     

The economic transformation of Eastern Europe: the case of Poland

This article identifies the main features of Poland's radical transition to capitalism-stabilization program, trade liberalization, and privatization reform. The shock therapy adopted by Poland in 1991 is presented as the most effective approach, though not without political risk. In fact, the major threat to Poland's transition process is the emergence of well organized interest groups putting increasing demand on the government to relax financial restrictions and re-open large-scale subsidization. These political pressures have already caused a slowdown in the privatization program, so that there is a possibility of the renewal of rapid inflation. Several methods for accelerated privatization, including the distribution of vouchers and setting up investment funds to manage portfolios of shares, are discussed in detail.     

Trade liberalisation and endogenous growth: Some evidence for Turkey

This paper examines the impact of trade liberalisation on the long-run economic development as measured by the real GDP per capita in Turkey. Based on the endogenous growth theory, we employ bivariate and multivariate cointegration analyses to test the long-run relationship among the relevant variables. Results for Turkey suggest a stable, joint long-run relationship among real GDP per capita, an index of trade liberalisation, human and physical capital in accordance with the endogenous growth theory. Statistically significant error-correction terms provide further evidence that those variables are indeed cointegrated. This also implies causal effects.

On the conceptualization of theoretical constructs

An attempt is made to bridge the gap between the theorists and modellists approaches to the conceptualization of theoretical constructs. The former approach assumes that every theoretical construct has a surplus meaning over and above its operationalization and measurement as a concept. The latter approach denies this: it only accepts theoretical constructs as functions of relations between observations, i.e. measured concepts.This gap can be bridged by explicating the definition of a theoretical construct before making attempts to operationalize and measure it. An explicated definition should cover all relevant aspects (or: facets) of a construct, systematically brought together in an ideal type model. On this basis, operationalization of the construct can be directly linked to model elements, so that any possibly remaining surplus value is made explicit. The distance between theoretical construct and the measured concept can then be made as small as seems feasible; in principle, the distance can be made zero. The manner in which conservative ideology is conceptualized in a longitudinal research project in the Dutch electorate is presented as an example of this strategy.     

Christofides’ randomized response technique in complex sample surveys

Christofides (2003) has given an improved modification of Warners (1965) pioneering randomized response (RR) technique in estimating an unknown proportion of people bearing a sensitive characteristic in a given community. As both these RR devices are shown to yield unbiased estimators based only on simple random sampling (SRS) with replacement (WR) but in practice samples are mostly taken with unequal selection probabilities without replacement (WOR), here we present methods of estimation when Christofides RR data are available from unequal probability samples. Warners (1965) RR device was earlier shown by Chaudhuri (2001) to be applicable in complex surveys. For completeness we present estimators for the variance of our estimator and also describe what to do if some people opt to divulge truths.This research is partially supported by CSIR grant No. 21(0539)/02/EMR-II     

Modelling structural change using the Kalman Filter

Structural change is endemic in the Eastern European economies and the newly emerging Commonwealth of Independent States, yet conventional econometric modelling techniques proceed under the assumption that there is a structurally stable true economy to be discovered. This paper explores the consequences of endemic structural change for econometric modelling by considering the model reduction problem when the data generation process is itself undergoing structural change. The resultant econometric model, it is argued will generally exhibit time varying parameters where much of the structural change is reflected in the changing parameters. The use of Kalman Filters to estimate such changing parameters is then discussed and a range of specifications which allow the inclusion of different forms of identifying information is given. The paper then illustrates these ideas by modelling the determination of the black market exchange rate in Poland over the period from the mid 1970s to the early 1990s.This paper was written as part of the A.C.E. project Methodology, Econometrics and Understanding the East European Economy in Transition.     

Foreign trade in the kaleckian perspective plan

In Kalecki's outline for a perspective plan a distinction is drawn between demand-determined and supply-constrained industries. Foreign trade operates on a vent-for-surplus principle whereby supply industries are run at full capacity and excess supplies (demands) are exported (imported). This policy is assessed using a simple two-sector model and is given only qualified support. Modifications to his plan procedure are accordingly suggested.     

Interaction of human and physical capital in a model of endogenous growth

A model of development is presented where growth is initially driven by physical capital accumulation, as in the neoclassical model. After a critical level of physical capital is reached, the economy takes off and enters a stage of sustained growth driven by human capital accumulation. The link between these two stages is provided by the assumption that private incentives for human capital accumulation increase with the average levels of human and physical capital. At the early stages of development, these incentives are low so the level of human capital stays stagnant until sufficient physical capital is accumulated. Other results are that some economies may reach a steady state of physical capital before a take-off is possible. This is especially likely for economies in which agents have low savings propensities. Such economies remain stuck in a no-growth equilibrium forever. Economies that do grow may experience endogenous cycles if the return to investment in human capital is sufficiently increasing in the level of physical capital.
