The global markets of renewable energy sources and the national interests of Russia

The current state and the prospects of the use of renewable energy sources (RES) in the world, their total and technical potential and fields of application, and their advantages and disadvantages in comparison with fossil kinds of fuel are considered. Special attention is given to nonconventional RES. The reasons why Russia is lagging behind in the use of these sources are analyzed.     

Deep habits and the dynamic effects of monetary policy shocks

We introduce deep habits into a sticky-price sticky-wage economy and examine the resulting models ability to account for the impact of monetary policy shocks. The deep habits mechanism gives rise to countercyclical markup movements even when prices are flexible and interacts with nominal rigidities in interesting ways. Key parameters are estimated using a limited information approach. The deep habits model can account very precisely for the persistent impact of monetary policy shocks on aggregate consumption and for both the price puzzle and inflation persistence. A key insight is that the deep habits mechanism and nominal rigidities are complementary: the deep habits model can account for the dynamic effects of monetary policy shock at low to moderate levels of nominal rigidities. The results are shown to be stable over time and not caused by monetary policy changes.     

Price and profitability in fish smoking in southwestern Nigeria

Comparative market prices for four freshwater and four marine fish species in the raw and processed forms were determined in a survey within Lagos and Oyo States of Nigeria. Costs of processed fish were calculated relative to the sale prices of their raw equivalents, taking moisture differences and cost of processing into consideration. All the species would have to be sold in the processed form for much higher prices than was found during the survey if sales were to be by weight. Processed catfish, sardine, mudfish and mackerel appear to be sold at a loss while three species (tilapia, sole and bongafish) are sold at very marginal profit. Only tigerfish is sold at reasonable profit. It is suggested that anyone going into fish smoking as a modern business venture should be prepared to face unfair competition in pricing from the small operators who appear to be underpricing their products and who currently dominate almost the entire fish market in Nigeria.     

Satisfaction with household production: the effect of time spent in household production by husbands and wives

The purpose of the study was to examine the relationship between the extent of household production and satisfaction with household production. Data were obtained from 400 married couples who responded to a postal questionnaire. The dependent variable was an index of satisfaction incorporating two aspects of household production, quality and quantity. Regression analysis indicated that of the three variables representing the extent of household production in the model — hours spent by each spouse in household production and an activity index to measure the number of household production activities — only husband's hours spent in household production demonstrated a significant, independent effect. Other significant variables included husband's hours of market work, household net worth, age of respondent and gender of respondent. Two significant interactions indicated that (i) the relationship between wife's hours of household production and satisfaction with household production differed according to the gender of the respondent, and (ii) the relationship of husband's hours of market work and satisfaction differed according to the age of the respondent.     

Real Incentive Effects of Soft Information

Both soft, noncontractible, and hard, contractible, information are informative about managerial ability and future firm performance. If a manager's future compensation depends on expectations of ability or future performance, then the manager has implicit incentives to affect the information. We examine the real incentive effects of soft information in a dynamic agency with limited commitment. When long-term contracts are renegotiated, the rewards for future performance inherent in long-term contracts allow the principal partial control over the implicit incentives. This is because the soft information affects the basis for contract renegotiation. With short-term contracts, the principal has no control over the basis for contract negotiation, and thus long-term contracts generally dominate short-term contracts. With long-term contracts, the principal's control over implicit incentives is characterized in terms of effective contracting on an implicit aggregation of the soft information that arises from predicting (forming expectations of) future performance. We provide sufficient conditions for soft information to have no real incentive effects. In general, implicit incentives not controllable by the principal include fixed effects, such as career concerns driven by labor markets external to the agency. When controllable incentives span the fixed effects of career concerns, the latter have no real effects with regard to total managerial incentives—they would optimally be the same with or without career concerns. Our analysis suggests empirical tests for estimating career concerns that should explicitly incorporate noncontractible information.     

Problems of information support for predicting labor migration in Russia

The main sources of information for the study of labor migration are discussed, as well as foreign experience in conducting surveys and application applying other sources of migration data. We propose methodological approaches to organizing a household survey to obtain information on labor migration including identification and selection of respondents and determination of basic sets of questions for the survey questionnaire.     

The Impact of Retirement on Household Leisure Expenditures

Household leisure expenditures for retired and near‐retired households were examined in order to better understand the dynamics associated with the move to retirement status. Data from the 1995 Consumer Expenditure Survey indicated that retirement, total expenditures, and education had positive impacts on leisure expenditures. For retired households, greater total expenditures and education increased expenditures, while age and the presence of earned income decreased expenditures. For near‐retired households, greater total expenditures, education, and the presence of asset income significantly increased leisure expenditures.
