Mortality,Human Capital and Persistent Inequality

Available evidence suggests high intergenerational correlation of economic status and persistent disparities in health status between the rich and the poor. This paper proposes a mechanism linking the two. We introduce health capital into a two-period overlapping generations model. Private health investment improves the probability of surviving from the first period of life to the next and, along with education, enhances an individual’s labor productivity. Poorer parents are of poor health, unable to invest much in reducing mortality risk and improving their human capital. Consequently, they leave less for their progeny. Despite convex preferences and technologies, initial differences in economic and health status may perpetuate across generations when annuities markets are imperfect.Additional support was provided by the National Science Foundation.

Reinvestigating the Nature of Persistence of Shocks in the Macroeconomic Variables Relating to the Indian Economy with Special Reference to Structural Changes and Seasonality

Over the last two decades, there is a substantial debate on the persistence of shocks, in terms of their transitory and permanent nature, caused to the macroeconomic aggregates. Macroeconomic variables with transitory shocks will revert back to the long-run deterministic path eventually, whereas variables with permanent shocks will move according to random walk having no fixed predetermined path. These two series known as Trend Stationary (TS) and Difference Stationary (DS), respectively, have their significance in the specification of the regression equation and testing competing economic theories. Consequently there are a good amount of studies to classify the macroeconomic aggregates as TS vs. DS. In this context, relatively new developments of seasonal integration and presence of structural breaks in the macro variables has aroused a need to reinvestigate these hypotheses afresh. This paper makes an attempt to examine some of these issues by making use of the Indian data.

     

Organizational and decision characteristics and personality as determinants of control actions: A laboratory experiment

This paper investigates how choice of control actions (or behaviours) is affected by the controller's personality and perceptions of organizational and decision characteristics. In a simulated work setting (n = 172) it was found that persons working in mechanistic organizations chose significantly different control tactics than those working in organic organizations. The present findings also suggest that controllers are more likely to choose extrinsically (rather than intrinsically) motivating controls when they are faced with important decision situations. The implications of the findings are discussed. Multivariate models of choice of control tactics in organizations are suggested as being more powerful.     

An explanation of share tenancy in terms of unemployment,social norms and power

Due to persistent unemployment, peasant families in developing countries tend to employ more labour on the leased in land plots than a capitalist would. In labour surplus societies, therefore, landlords may earn higher surplus from leasing out land than from self-cultivation. By endogenising disguised unemployment this paper shows that greater power and unity of landlords and conservative social norms may explain the persistence of share tenancy in developing economies.     

Efficiency with costly information: a reinterpretation of evidence from managed portfolios

We investigate the informational efficiency of mutual fund performancefor the period 1965-84. Results are shown to be sensitive tothe measurement of performance chosen. We find that returnson S&P stocks, returns on non-S&P stocks, and returnson bonds are significant factors in performance assessment.Once we correct for the impact of non-S&P assets on mutualfund returns, we find that mutual funds do not earn returnsthat justify their information acquisition costs. This is consistentwith results for prior periods.     

Accounting for the role of habit in behavioural strategies for injury prevention

The limited success of behavioural strategies in injury prevention has been attributed to failure to properly apply behaviour change models to intervention design and the explanation of safety behaviours. However, this paper contends that many health behaviour change interventions do not succeed because they fail to take into account the habitual quality of most health and safety-related behaviour; a more complete model of behaviour change needs to be based on a better understanding of the role of habit. The overall aim is to contribute to better understanding of behavioural strategies for injury prevention. When habits are weak, attitudes and intentions predict behaviours, but as behaviours turn into habits, they become better predictors of future behaviour than attitudes or intentions. Furthermore, where habits are strong, individuals are less likely to act on new information, evaluating counter-habitual information negatively. Integrating the concepts of strong and weak habits with upstream and downstream strategies, a framework is presented for tailoring strategies to the habit strength of the target behaviour.     

Panel unit root tests under cross-sectional dependence

In this paper alternative approaches for testing the unit root hypothesis in panel data are considered. First, a robust version of the Dickey-Fuller t -statistic under contemporaneous correlated errors is suggested. Second, the GLS t -statistic is considered, which is based on the t -statistic of the transformed model. The asymptotic power of both tests is compared against a sequence of local alternatives. To adjust for short-run serial correlation of the errors, we propose a pre-whitening procedure that yields a test statistic with a standard normal limiting distribution as N and T tends to infinity. The test procedure is further generalized to accommodate individual specific intercepts or linear time trends. From our Monte Carlo simulations it turns out that the robust OLS t -statistic performs well with respect to size and power, whereas the GLS t -statistic may suffer from severe size distortions in small and moderate sample sizes. The tests are applied to test for a unit root in real exchange rates.     

Power Politics and International Labor Standards

This paper analyzes how a country's commitment to labor standards is affected by the international political power they possess. Powerful countries may be less committed to actual enforcement of certain labor standards since they are unlikely to face significant threats of international sanctions regardless of their actions. The paper introduces an index of international power for 116 countries that is used to examine how power affects the extent to which countries enforce standards relating to freedom of association and collective bargaining. The evidence suggests that, even after controlling for differences in wealth, productivity, and market freedom, powerful countries are significantly less committed to the protection of labor standards than less powerful countries.

Changing Perceptions and Changing Behavior in Customer Relationships

We formulate a theoretical model in which we postulate that if customers' behavior is perceived as not optimal, customers will adjust this behavior based on their current satisfaction and payment equity. Furthermore, customers will also include new experiences. In our empirical study we particularly investigate customer referrals and the amount of services purchased. Our results show positive effects of current satisfaction and payment equity on referrals, while also changes in satisfaction and payment equity affect customer referrals. With respect to the amount of services purchased, our estimation results reveal a positive significant effect of only changes in satisfaction.     

Consumers' awareness,acceptance and attitudes towards functional foods in Turkey

The aim of the present study was to investigate consumers' awareness, acceptance and attitudes towards functional foods in Turkey. Eight hundred and eight people participated in this study: aged between 20 and 80 years, 38.5% were male and 61.5% were female. Participants were given a questionnaire and were asked to fill it in by themselves to minimize the influence of the interviewer. Results indicated that socio‐demographic characteristics such as age, education level and income level are important indicators of consumers' awareness and consumption of functional food. The results show that the female respondents were 2.987 times more aware of functional food than the male respondents. Similarly, the likelihood of respondents having awareness of functional food was 1.431 times greater among those who had a higher educational level than among those with a lower educational level. Consumers who used vitamin supplements were 1.228 times more aware of functional food than other consumers. The results show that older respondents were 3.395 times more aware of functional food than younger respondents. Respondents with a history of familial diseases were more likely than others to have consumed margarine with plant sterol, fruit juices fortified with vitamin C, and breakfast cereals fortified with vitamins and minerals. Those with a diet‐related problem were more likely to have consumed cholesterol‐lowering products than those without a problem. As a conclusion, this study has shown that socio‐demographic characteristics such as age, education and income levels, and prices are important indicators that influence consumers' awareness and consumption of functional food. These results suggest that this type of knowledge could affect consumers' interest in functional foods, and therefore educational strategies might be necessary to encourage the consumption of functional foods.
