Low agricultural productivity remains the primary source of poverty in the developing regions and yet little is known about the influence on agricultural productivity of domestic and international accumulated R&D knowledge and the channels through which this knowledge is transmitted internationally. Following a large scientific literature, this article argues that R&D and R&D knowledge spillover are ecozone‐specific and, therefore, are transmitted internationally through ecozones, where ecozones are the broadest biogeographic division of the earth's land surface. Using data for a panel of 88 countries, it is shown that international knowledge spillovers are ecozone‐specific and have been an important contributing factor behind the marked widening of the income gap between developed and developing countries since 1983. 相似文献

Using data for a long panel of 90 developed and developing countries, this article explores the effects of research and development (R&D) and fixed capital stock on agricultural land productivity over the period 1961–2012. Instruments are used for R&D to deal with feedback effects and measurement errors. The results show very high social returns to investment in R&D and to fixed capital stock, suggesting that increasing investment in these factors are promising ways of arresting the increasing food prices due to increasing demand for animal protein, population growth, desertification, salinization, soil erosion, climate change, and decreasing growth in land productivity. 相似文献

Australia's and Canada's real wage experiences between 1870 and 1913 were distinctive. Faster productivity growth underpinned Canada's overtaking of Australia's wage levels. The globalization forces of migration and trade also shaped their comparative wages, principally by reducing wage growth in Canada. Immigration increased slightly Australia's real wages, but reduced wage levels in Canada, and tempered there the beneficial effects of rising productivity and improving terms of trade. In contrast, wage earners' share of national income rose after 1890 in Australia, with the productivity slowdown hitting chiefly rents and profits. Distributional shifts favouring wage earners in Australia, and the depressing effects of mass immigration on wages in Canada, limited Canada's wage lead before 1914, despite her faster productivity growth. 相似文献

Empirical tests of the Fisher hypothesis give conflicting results, regardless of whether income growth is accommodated in
the estimates. This paper shows theoretically and empirically that standard methods of testing the Fisher hypothesis give
biased results and that the bias depends on the specification of the Fisher equation, the process governing inflation, measurement
of inflation expectations, and the time aggregation of the data. Alternative tests show that share markets take several years
to adjust to innovations in inflation and therefore that the Fisher hypothesis cannot be maintained.

This study focuses on the importance of changes in entrepreneurial orientation (EO) over time for subsequent firm performance, and the significance which inimitable resources (networks, governance system and unique competence) might have in this connection. Hypotheses are developed to test the effects that changes in EO level over a time period and resources have on subsequent firm performance. The study is based on data from 168 Norwegian SMEs, interviewed both in 2000 and 2003. The primary contribution of this study is that a change in EO over time (increased or decreased), may be of importance for a firm's performance represented by performance compared to competitors, and employment growth. A focus on entrepreneurial activities seems to be beneficial in the long run (increasing EO), while the opposite is the case if the EO level decreases. It is especially encouraging to see that firms focusing on EO (increased or the same) are positively associated with employment growth, one of the primary policy goals world-wide. Another contribution from this study is that resources that may be inimitable for firms have some influence on performance compared to competitors. Implications for policy-makers, practitioners and further research are discussed. 相似文献

This paper examines the impact of macroeconomic policies in a general equilibrium system where the product market is modelled as an oligopolistic supergame. It is shown that policies which affect the interest rate, influence the degree of competition and hence the level of output in the economy. The analysis reveals that some macroeconomic policies may have perverse and counter intuitive effects in the system. 相似文献

This paper investigates the macroeconomic effects of switching the tax burden from direct to indirect taxes in an empirical model based on 22 OECD countries. The Engle-Yoo three step procdure is employed to estimate both the short and long run effects of such a tax switch. The results reveal that a switich from direct to indirect taxes is likely to generate efficiency gans in the short run which lead to higher levels of aggragate output. However, for the majority of countries in the sample the tax changes have no impact on the level of economic activity in the long run. 相似文献

The paper presents an interregional computable general equilibrium model, LINE, which is used to analyze the regional economic effects of changes in road pricing as they affect and work though the Danish tourism sector. These effects include changes in demand, income and employment by region. The form of road pricing examined in the paper is tolls across a major fixed link. The consequences of changes in these substantial tolls are examined using the modeling framework. The basic modeling approach in LINE is presented, including its tourism sub-model, and empirical results for Denmark are examined. 相似文献
