Economic Impacts of Technology,Population Growth And Soil Erosion At Watershed Level: The Case Of the Ginchi in Ethiopia

A dynamic bio‐economic model is used to show that, without technological and policy intervention, soil loss levels, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise by more than 40% over a twelve‐year planning period, average per ha soil losses could be as high as 31 tonnes per ha. With the adoption of an integrated package of new technologies, however, results show the possibility of an average two‐and‐a‐half‐fold increase in cash incomes and a 28% decline in aggregate erosion levels even with a population growth rate of 2.3%. Moreover, a minimum daily calorie intake of 2000 per adult equivalent could be met from on‐farm production with no significant increases in erosion. However, higher rates of growth in nutritional requirements and population introduce significant strains on the watershed system. From a policy perspective, there is a need for a more secure land tenure policy than currently prevailing to facilitate uptake of the new technology package, and a shift from the current livestock management strategy to one that encourages livestock keeping as a commercial enterprise. It would also imply a shift to a more site‐specific approach to land management.     

Foreign capital inflows,domestic savings and the price of political stability in the sudan: Weisskopf revisited

This paper reworks Weisskopf's estimates of the effect of foreign capital inflow on domestic savings for a later time period. The Sudan is presented as an example of a public sector dominated economy, dependent on one major export crop and politically unstable. While Weisskopf's savings function had an indication of a negative relationship between public sector savings and official foreign capital inflow, problems of collinearity between the independent variables cast doubt on its utility for analysis of economies dependent on limited primary exports. The negative relationship between public sector savings and official is explained in terms of the expansion of the state's bureaucracy and military.     

Do consumption expenditures depend on the household’s relative position in the income distribution?

Even though the permanent income and relative income hypotheses have been introduced in past research to explain consumer behaviour, no previous attempt was undertaken to integrate them in one model. In this article, the hypotheses were synthesized into a single model. The model was empirically tested using data from the 1996 Canadian Family Expenditure Survey. The results indicate that household consumption behaviour is generally explained by both hypotheses when integrated into one model, contrary to previously treating them as mutually exclusive hypotheses.     

Systèmes De Gestion Des Ressources Humaines Et Performance Organisationnelle

Résumé ** :  La gestion des ressources humaines et son effet sur la performance de la firme représentent encore de nos jours une zone d'indétermination. Plusieurs théories tentent d'ailleurs d'expliquer cette importante relation. C'est l'approche configurationnelle des ressources humaines qui servira de filtre théorique à cette recherche. Validant cette approche auprès de 46 entreprises financières canadiennes, nous avons démontré, en partie du moins, la robustesse de cette approche stratégique de gestion des ressources humaines. Il ne fait aucun doute qu'une telle approche représente une alternative stratégique intéressante, capable d'accroître l'efficacité de nos firmes dans ce monde économique impitoyable et mondialisé.     

The balance sheet channel of monetary policy: the panel evidence of Egypt

This paper examines the effects of monetary policy on firms’ investments in Egypt using disaggregated data and generalized method of moments (GMM) technique. It develops the neoclassical investment model by adding the interaction between user cost of capital and cash flow (CF). Therefore, monetary policy affects investment through three effects: user cost of capital, CF and interaction between them. Using a sample of 124 firms, the empirical finding supports the relevance of balance sheet channel (BSC) and the heterogeneous effect of monetary policy on investment. This finding signals that monetary authority should take cognizance of the stability of interest rate to stabilize firm-level investment.     

Investigating the causality links between environmental quality,foreign direct investment and economic growth in MENA countries

This paper investigates the causal relationship between environmental quality, Foreign Direct Investment and economic growth using simultaneous-equation panel data VAR model a panel of 17 MENA countries over the period 1990–2012. Our empirical results pointed out that there is a unidirectional causality running from both FDI stocks and CO₂ emissions to economic growth. They also indicate the existence of unidirectional causality running from economic growth to CO₂ emissions. However, the results support the occurrence of unidirectional causality from FDI stocks to CO₂ emissions. Our empirical result confirms the hypothesis of neutrality for the Environment-GDP link. There is bidirectional causality from ${\text{CO}}_2$emissions and economic growth, and a bidirectional causal relationship between FDI stocks and CO₂ emissions. For the global panel, we show that the existence of a unidirectional causality running from FDI stocks to economic growth; a bidirectional causality between economic growth and CO₂ emissions; as well as a bidirectional causality between FDI stocks and ${\text{CO}}_2$emissions.     

The effect of mode 4 liberalization on illegal immigration

This paper aims to assess the impacts of the temporary movement of workers on the illegal immigration. It uses a discrete time, forward-looking model with heterogeneous agents, in order to describe the decision made by illegal migrants from developing countries. Illegal migrants are supposed to accede only to the informal sector and are price takers, as they have no negotiating power. Taking into account these specifications, the theoretical model is solved analytically and illustrated numerically. It demonstrates that under some conditions, the liberalization of temporary movement of workers could lead to a decrease of illegal migration.     

Schumpeterian competition and efficiency among commercial banks

In this paper, we aim to fill the gap in the banking literature by quantifying the impact that the Schumpeterian competition mode – i.e. competition through the launch of new products (or new varieties of products) – has on the cost and profit efficiency of a sample of commercial banks based in the United Kingdom. We estimate both a cost and an alternative profit frontier on an unbalanced panel of UK commercial banks over the period 2001–2012. The intensity of competition through product innovation is proxied by the trademark intensity (i.e. the ratio between the number of trademarks registered in a given year by all the commercial banks – net of the trademarks registered by the bank under observation – and the employment in the sector) in the commercial banking sector. Our results show that the (lagged) trademark intensity in the commercial banking sector does affect negatively the mean cost and profit efficiency in the sector but there is evidence that as trademark intensity increases in the sector, commercial banks react by improving their cost and profit efficiency.     

Analysis of the effect of risk management practices on the performance of new product development programs

Risk management is receiving much attention, as it is seen as a method to improve cost, schedule, and technical performance of new product development programs. However, there is a lack of empirical research that investigates the effective integration of specific risk management practices proposed by various standards with new product development programs and their association with various dimensions of risk management success. Based on a survey of 291 product development programs, this paper investigates the association of risk management practices with five categories of product development program performance: (A) Quality Decision Making; (B) High Program Stability; (C) Open, problem solving organization; (D) Overall new product development project success; and (E) overall product success. The results show that six categories of risk management practices are most effective: (1) Develop risk management skills and resources; (2) Tailor risk management to and integrate it with new product development; (3) Quantify impacts of risks on your main objectives; (4) Support all critical decisions with risk management results; (5) Monitor and review your risks, risk mitigation actions, and risk management process; and (6) Create transparency regarding new product development risks. The data shows that the risk management practices are directly associated with outcome measures in the first three categories (improved decision making, program stability and problem solving). There is also evidence that the risk management practices indirectly associate with the remaining two categories of outcome measures (project and product success). Additional research is needed to describe the exact mechanisms through which risk management practices influence NPD program success.
