The skill premium and economic growth with costly investment,complementarities and international technological-knowledge diffusion

We analyse the skill premium and the growth rate in an innovator-imitator general equilibrium growth model assuming (i) internal costly investment in both physical capital and R&D, (ii) complementarities between intermediate goods in production and (iii) technological-knowledge diffusion. We find that in the imitator country these three elements influence the economic growth rate and the skill premium. In the innovator country, while the growth rate is affected by costly investment and complementarities, the skill premium is not affected by any of our assumptions. It depends solely on the productive advantage of high-skilled over low-skilled labour, which suggests that the sustained increase in the skill premium observed in several developed countries over the last three decades may have been due to increases in such productive advantage.     

Incentives and disincentives for stakeholder involvement in participatory research (PR): lessons from potato-related PR from Bolivia,Ethiopia, Peru and Uganda

Participatory research (PR) has been presented as an alternative to develop sustainable agricultural technologies more responsive to farmer needs. However, the institutionalization of PR methods is influenced by stakeholders' perceptions about incentives and disincentives. The study was conducted by gathering and analysing information from farmers, facilitators and institutional representatives involved in conducting potato-related PR in Bolivia, Ethiopia, Peru and Uganda between 2005 and 2007. Results indicate that at the farmer level the most important incentives are related to the benefits they can acquire (improving human and social capital, which is essential for more sustainable results). At the facilitator level, operational and organizational factors represent incentives, for example, perception of additional benefits, existing capabilities and skills, and access to logistic support. Some factors also represent disincentives such response to different types of demands, and instability of jobs within institutions. At the organization level, both financial and operational factors represent incentives or disincentives, such as the cost of PR methods, availability of skillful human resources, quality of technologies generated and the sustainability of financial support. These factors at both individual and organizational level need to be taken into consideration by organizations aiming at scaling up and out-of-PR methods and derived technologies in a sustainable way.     

Who actually goes to university?

Access to higher education (HE) is a major policy issue in England and Wales. There is concern that children from lower socio-economic backgrounds are far less likely to get a degree. We analyse the changing association between socio-economic background and the likelihood of going to university, using data from the Youth Cohort Study (YCS), spanning the period 1994–2000. We find evidence of substantial social class inequality in HE participation but conclude that this is largely due to education inequalities that emerge earlier in the education system. Conditional on GCSE and A level performance, we find no additional role for socio-economic background or parental education in determining pupils’ likelihood of going to university.     

Bioeconomic modeling for control of weeds in natural environments

When a weed invasion is first discovered a decision has to be made on whether to attempt to eradicate it, contain it or do nothing. Ideally, these decisions should be based on a complete benefit-cost analysis, but this is often not possible. A partial analysis, combining knowledge of the rate of spread, seedbank longevity, costs of control and techniques of economic analysis, can assist in making a good decision. This paper presents a decision model to determine when immediate eradication of a weed should be attempted, or more generally whether weed control should be attempted at all. The technique is based on identifying two ‘switching points’: the invasion size at which it is no longer optimal to attempt eradication but where containment may be an option; and the invasion size at which it becomes optimal to apply no form of control at all. The model is applied to a woody perennial weed in a natural environment. The results show that seedbank longevity is the main constraint on the maximum eradicable area and spread rate is the main constraint on the maximum containment area. Stochastic simulations are undertaken to derive probability distributions of costs which are than used to evaluate the effect of budget constraints on areas that can be eradicated. We find that, in the absence of a budget constraint, it may be desirable to eradicate invasions from areas as large as 8000 ha, but when budget constraints typical of those faced by agencies in Australia are introduced, feasible eradicable areas are less than 1000 ha.     

A Quantitative Analysis of the Effects of Capital Controls: Spain, 1986–1990 *

This Paper offers a quantitative assessment of the effectiveness of capital controls in Spain during the period 1986-1990. The analysis is based on a portfolio-balance model Previously estimated for the Spanish economy, where the complete elimination of capital controls is simulated. Our results suggest that capital controls would have avoided a net capital outflow amounting to nearly a 4 per cent increase in the Spanish net foreign asset position, as a quarterly average, during the first five years of Spanish membership into the EU.

The Labor Market Effects of FDI: A Panel Data Evidence from Mexico

ABSTRACT

This paper explores the effects of Foreign Direct Investment (FDI) inflows on six labor market outcomes by using a panel data of the Mexican states from 2005 to 2015. By relying on the system Generalized Method of Moments estimator to address potential endogeneity of FDI in the labor market outcomes regressions, this study finds that the FDI inflows result in a reduction in the overall unemployment rate. Moreover, the FDI is associated with a decrease in the percentage of employed people with the need and availability to offer more working hours and an increase in the median hourly wage rate. The FDI is not likely to influence the critical employment, informal sector employment, and unemployment duration.     

Comprehensive Homeowners Microinsurance in Brazil: Estimation of Pricing and Market Potential

This study examines the question of comprehensive microinsurance for Brazilian homeowners. In particular, the study calculates (i) pricing for selected types of microinsurance homeowner's coverages and insured amounts and (ii) the estimated market potential of this product. The Brazilian agency charged with responsibility for regulation of private insurance, SUSEP, has determined that microinsurance should be aimed at families with a monthly per capita income of up to two minimum wages. According to this criterion, the study finds that there are more than 42 million households in Brazil eligible for microinsurance. The study also finds that microinsurance premiums for these households would be very low (US $0.97 to 2.03 per month)—less than 1% of average household income. This type of insurance would certainly be viable, considering the calculated market size of approximately US $780 million per year. These figures show that there is significant potential for the expansion of the microinsurance market in Brazil.     

Environmental Motivations: The Pathway to Complete Environmental Management

The aim of this research is to ascertain whether a firm’s environmental motivations may help to predict how complete or incomplete its environmental management will be, understanding incomplete management to be that which neglects one or more of the three keys aspects of such management, namely, monitoring, action and results. We specifically posit that while motivations based on the search for legitimation lead to more incomplete styles of environmental management, competitive motivations entail a more complete management. The analyses conducted with a sample of 1,902 plants provide empirical evidence in favour of such reasoning. The contribution this research makes, therefore, is not restricted solely to showing the effect motivations have on the environmental performance of organisations, as it also introduces a new dimension of environmental management—the degree of completeness, which needs to be considered when understanding and evaluating this effect.
