Implications of nanotechnology growth in food and agriculture in OECD countries

This article provides an analysis of the implications of the growth of nanotechnology in the agriculture and food sector in OECD countries. Three main policy challenges are identified related to funding and investment, risk governance, and public acceptance. Each of these interconnected challenges underlines a number of ethical questions that need to be addressed. Several recommendations are laid out to move forward and adapt to these emerging policy issues.     

论OECD国家税收改革成效及其政策有效性

作为世界上最发达国家代表的OECD组织,其税收政策在过去的三十年中经历了一系列的改革。从税收政策有效性的角度看,这些改革的效果究竟怎样?本文以此为基本思路,首先从制度经济学的角度对税收政策及其有效性进行新的诠释;其次从改革实践和改革成效两个方面分析OECD国家的税收改革;再次对OECD国家税收改革的有效性进行了评价,最后得出一些启示。     

Savings and investments in the OECD, 1970–2007: A test of panel cointegration with regime changes

In this paper we test for the existence of a long-run relationship between investment and savings (the Feldstein–Horioka puzzle) in a panel of 18 OECD countries, 1970–2007, allowing for heterogenous breaks in the coefficients. For this purpose we develop a bootstrap panel cointegration with breaks robust to cross-section dependence, shown by simulation to enjoy good size and power properties provided that some care is applied in its use. The tests suggest that, even allowing for parameter shifts in the countries where capital control regulations changed in the sample period, there is no evidence of an investment–savings long-run relationship for the panel as a whole.     

The Dynamic Effects of Public Capital: VAR Evidence for 22 OECD Countries

The issue of whether public capital is productive has received a great deal of recent attention. Yet, empirical analyses of public capital productivity have been limited to a small sample of countries for which official capital stock estimates are available. Building on a new database that provides internationally comparable capital stock estimates, this paper estimates the dynamic effects of public capital using the vector autoregressive (VAR) methodology for a large set of OECD countries. The empirical results suggest that there is evidence for positive output effects of public capital in OECD countries, but hardly any evidence for positive employment effects.JEL Code: C32, E62, H54     

Macroeconomic performance and convergence in OECD countries

This paper investigates the robustness of the correlation between growth and a set of variables which comprises accumulation rates in human and physical capital and medium term macroeconomic indicators in OECD countries. We include these variables as additional regressors in the standard growth equation that comes from the human capital-augmented Solow model. Our results show that variables related to medium term macroeconomic performance affect both growth and convergence. In some periods these variables even outperform the explanatory power of the conventional growth variables such as the accumulation rates. Our results also suggest that it is difficult to analyse the contribution to growth of any particular macroeconomic indicator in an isolated way. Rather, these effects should be studied in a framework that accounts for the macroeconomic performance of a country.     

PPP in the 34 OECD countries: evidence from quantile-based unit root tests with both smooth and sharp breaks

Conventional unit root tests have mostly failed to validate the PPP. Quantile-based unit root tests by previous research have provided some support for the PPP. In this article, we take an additional step and incorporate sharp shifts and smooth breaks into the quantile-based unit root test and re-examine the PPP in each of the 34 OECD countries over the period 1994:01–2016:03. We find support for the PPP in 18 countries of Austria, Chile, Estonia, Finland, France, Germany, Italy, Korea, Mexico, Netherlands, New Zealand, Poland, Portugal, Slovenia, Sweden, Switzerland, Turkey and the United Kingdom.     

Inflation,a disease of society

This paper focuses on financing the welfare state expenditures in the UK. It offers a comprehensive analysis of social expenditures and taxes paid by the working population families, and an estimation of the net benefits received by them. While the subsequent analysis of the welfare state and its development primarily concentrates on the British experience, it has a broader application to other OECD countries. The UK as the most egalitarian “liberal market economy,” offers an interesting case for the study of the interaction between the welfare state expansion and economic growth. In terms of her capitalist economic structure, (interaction between market and economy) she is relatively closer to the USA and other Angelo-Saxon (liberal market) economies. In terms of her level of social expenditures, she is much closer to the European “social market economies” than the USA and other more egalitarian “liberal market economies.”     

Energy consumption,economic growth and environmental degradation in OECD countries

The interdependence among energy consumption, economic growth and environmental degradation has become an important public policy priority among OECD countries. Yet, the related literature provides conflicting results when describing the dynamic nature of such a relationship and the way it affects countries' development path. Using a sample of 35 OECD countries over the period 2000–2014, we find that economic growth and energy consumption patterns contribute to the enhancement of countries' environmental performance levels. In contrast to a large stream of empirical research, our findings highlight that countries' economic development path and their energy consumption patterns have started to align with their environmental policies. The results are robust since we utilize different aspects of countries' environmental degradation such as carbon dioxide emissions, ecological footprints and countries' environmental performance levels. Finally, the analysis of the dynamic interrelations among countries' energy consumption, economic growth and environmental degradation levels, reveals the necessity to promote sustainable development through a coexistence rather than through a trade-off mechanism.

Real Output Convergence and Trade Openness: Fuzzy Clustering and Time Series Evidence

In the now extensive literature on the convergence of real per capita output across countries over time, there is surprisingly little attention paid to the role of international trade. Some recent studies have illustrated that standard trade theories provide no clear prediction as to the impact of trade liberalization on output convergence. These studies have also provided somewhat ambiguous empirical evidence regarding this relationship, under-scoring the need for additional results in this area. This paper uses both standard and new approaches to testing for convergence in order to explore the extent to which the degree of trade openness may affect output convergence among countries. Using annual time-series data for 88 countries from the Penn World Table, we obtain somewhat mixed results, but on balance they are quite supportive of a positive relationship (though not necessarily causality) between trade openness and output convergence. Our results also suggest certain directions for further research that would shed more light on this important issue.
