Mineral resources for renewable energy: Optimal timing of energy production

The production of energy from renewable sources is much more intensive in minerals than that from fossil resources. The scarcity of certain minerals limits the potential for substituting renewable energy for scarce fossil resources. However, minerals can be recycled, while fossil resources cannot. We develop an intertemporal model to study the dynamics of the optimal energy mix in the presence of mineral intensive renewable energy and fossil energy. We analyze energy production when both mineral and fossil resources are scarce, but minerals are recyclable. We show that the greater the recycling rate of minerals, the more the energy mix should rely on renewable energy, and the sooner should investment in renewable capacity take place. We confirm these results even in the presence of other better known factors that affect the optimal schedule of resource use: expected productivity growth in the renewable sector, imperfect substitution between the two sources of energy, convex extraction costs for mineral resources and pollution from the use of fossil resources.     

Global Expansion of Renewable Energy Generation: An Analysis of Policy Instruments

This study analyzes the degree to which renewable energy policies, in particular feed-in tariffs and renewable portfolio standards, facilitate renewable energy generation growth across a wide range of countries using an original cross-national dataset of 164 countries between 1990 and 2010. Results provide evidence that both policies are important predictors of renewable energy market growth. The dependent variable is operationalized first as the percentage of total electricity from renewable energy and second as the annual increase in total renewable energy generation in a country. Results are robust to several alternative model specifications including those that exclude hydroelectric generation in the construct of renewable energy. The degree to which feed-in tariffs are endogenous, however, is not conclusive. Besides the prominent role of these policies, results reveal that factors related to annual increases in renewable energy differ from those related to an overall transition toward greater reliance on renewable energy. This suggests that simply increasing renewable generation does not necessarily decrease reliance on fossil fuels or help countries make the shift to a clean energy economy.     

信息化能促进农户的市场参与吗?--来自中国苹果主产区的微观证据

在转型时期,信息化工具的引入对农户打破低水平均衡、改善信息困境、提高市场进入能力具有重要作用。文章基于比较静态分析和专业化苹果主产区微观调查数据的实证分析表明,手机和电脑这两种信息化工具的应用能够改善信息的流动性和共享程度,会对农户的销售市场选择和垂直协作参与产生正向的促进作用。此外,电脑和互联网的引入也有助于提高农户的信息可得性以及与收购商的博弈能力,进而对农产品销售价格产生积极影响。因此,进一步克服自然环境和社会经济条件的约束,提高信息化工具普及率,注重农产品生产、销售相关信息的搜集和发布等信息源建设仍是农村信息化工作的题中之意。     

SWEEA—Swedish environmental and economic accounts

As part of the Swedish effort at integrating economic and environmental issues, Statistics Sweden has developed a system of physical environmental accounts. The system is based on the concept of satellite accounts which supplement the traditional national accounts. Here, Statistics Sweden focuses on the chain linking natural resources to economic activities and emissions. Current projects include the use of energy and the emission of pollutants, statistics on waste generation and recycling, and accounts for phosphorus and nitrogen flows. Attention is also paid to improvements of data on expenditures on environmental protection.     

Development of smart microgrid powered by renewable energy in China: current status and challenges

During the ‘13^th Five-Year Plan period’ (2016–2020), one of the main targets for China's energy strategy is to develop a new generation of power system, integrating high shares of renewable energy sources. This implies that the technology industrialisation of microgrid powered by distributed generation of renewable energy is becoming crucial. This paper carries out a comprehensive study of the status and challenges of developing microgrid, based on case studies of demonstration projects of microgrid in China during different developmental stages. The focus is on the effects of government policies, technical innovations and changes in the business model of electricity market on the promotion of microgrid in China and the reformation of electricity market in China. The ultimate target for the reformation of power system in China is to finish the transformation from a linear business model of centralised power system.

The Effect of Feed-in Tariffs on Renewable Electricity Generation: An Instrumental Variables Approach

While carbon taxes and other market-based instruments are widely regarded as optimal for climate mitigation, political constraints have prevented governments from using them. Instead, narrower instruments, including the feed-in tariff (FIT) for renewable electricity generation, have become popular. However, their causal effect on renewable electricity generation remains subject to uncertainty. We use instrumental variables to estimate the causal effect of FITs on renewable electricity generation in 26 industrialized countries, 1979–2005. We find that increasing the FIT by one U.S. cent (2000 constant prices) per kilowatt hour increases the percentage change in renewable electricity’s share of the total by 0.11 % points. All else constant, if a country implemented for a decade the sample mean FIT of three U.S. cents, the national share of renewable electricity would increase by 3.3 % points, which is more than the sample mean. In addition to demonstrating that the FIT is an effective way to increase renewable electricity generation, our approach lays the foundation for future studies of the causal effects of renewable energy policies.     

英国可再生能源产业发展现状

英国在发展可再生能源方面具有良好的自然条件,特别在离岸风能及波浪能和潮汐能方面。但英国在开发这一潜力方面做得并不够好,目前,英国来自可再生能源的发电量占其全部用电需求的不足5％,远远落后于世界上一些先进国家。这其中有多方面的原因,如英国的入网电价相对便宜（与欧洲其他国家相比）,政府对可再生能源行业的财政补贴较少,以及在批准可再生能源项目方面遇到的延误和障碍较多等等。但是,随着近些年一系列鼓励政策和措施的出台,英国在可再生能源方面会有一个较为光明的前景,从而实现它确保能源安全及减少温室气体排放的双重目标。     

The Determinants of Location Choices of China's ODI: Institutions,Taxation and Resources

China has become the third largest source of outward direct investment (ODI). This paper studies how institutions in the host countries affect the location choices of China’s ODI. Based on a deal-level sample from 2002–2011, this paper empirically tests how political institutions, political stability, government effectiveness, regulatory quality, rule of law and contrd of corruption in the host countries affect the location choices of China’s ODI. On top of these institutional factors, we study the effects of tax evasion and natural resources in host countries, and their interactions with institutional factors. We find that political institutions in the host countries are not major concerns of the ODI, while government effectiveness, regulatory quality, and control of corruption have significant effects on the locations of ODI. In addition, China’s ODI tends to avoid countries with strict legal systems. Tax evasion and resources are also major motives of China’s ODI. General institutional quality and tax evasion are substitutes in China’s ODI location decisions.     

Looking for the workforce: the elderly,discouraged workers,minorities, and students in the Baltic labour markets

This paper looks at the evolution of the labour markets in Estonia, Latvia, and Lithuania since the beginning of transition until 2003, with a particular focus on labour force participation. How did labour supply in the Baltic countries respond to changes in minimum wages, unemployment benefits and retirement regulation? Do the marked differences in labour market policies between the countries result in different patterns of participation? What are the obstacles to and driving forces of participation? We find that relative contribution of participation and demographic trends to the dynamics of the labour force varied substantially both over the years and across the three countries. Participation, in turn, has been shaped by sometimes complicated interactions between schooling decisions of the youth, retirement, policy changes, and external shocks. Resulting differences in trends and patterns are quite substantial, indicating that there is a room for increasing participation in each of the countries. Panel data analysis of determinants of participation and discouragement based on labour force survey data suggests that increasing after-tax real minimum wage has significant positive effects on participation and reduces discouragement in Lithuania. In Estonia, by contrast, a positive effect of minimum wage on participation is found only for teenagers of both genders and for young males. We do not find any evidence that partner’s wage has a negative effect on participation. Ethnic minorities, especially females, in all three Baltic countries are less likely to be in the labour force, other things equal.     

The share of the global energy mix: Signs of convergence?

This paper investigates the convergence behaviour regarding the share of global energy mix, as measured by primary energy consumption. Recent studies that employ stationary tests of panel data suggest that such data support the convergence hypothesis; however, some drawbacks exist, as these studies rely on methods that do not necessarily imply a sufficient condition for convergence. This paper adopts the concept of relative convergence as proposed by Phillips and Sul (2007), which employs a time‐varying, idiosyncratic component. We choose to focus on various sources’ global primary energy consumption and investigate the long‐ run dynamic behaviour by source. The key finding of this paper is that two distinct clubs of convergence of energy can be determined: renewable and non‐renewable energy clubs of convergence.

An econometric assessment of telecommunications prices and consumer surplus in Mexico using panel data

We analyze telecommunications prices in Mexico by using a panel data of countries similar to Mexico to estimate demand models for mobile and fixed-line telecommunications. We find that Mexico’s actual mobile and fixed-line prices are below the predicted prices based on similar countries’ prices. Mexican consumers are paying lower prices than what one would expect based on comparisons of comparable countries. We calculate that in 2011 Mexican consumers received at least $4–$5 billion (USD) in consumer surplus from these lower mobile prices and in 2010 they received over $1 billion (USD) in consumer surplus from these lower fixed-line prices. These findings are in contrast to the general perception that concentrated telecommunications markets in Mexico are resulting in high prices and harming consumers.     

Evaluation of elderly households’ financial standing in Central and Eastern European countries

The purpose of the paper is to analyse and evaluate the financial situation of elderly households in Central and Eastern European (CEE) countries. Current demographic trends simultaneously with reforms of pension systems in the CEE region may lead to an increasing number of elderly households being exposed to poverty risk. In this study, Ward’s method and the method of standardised sums were applied to classify and order the examined countries according to the financial standing of elderly households. The obtained results allow us to identify countries with similar financial situations for elderly households in 2007, 2010 and 2013, and changes in clusters and ranking over the analysed period. The main findings show that the financial situation of the elderly in CEE countries is very differentiated and changeable, however over the analysed period the financial standing of the elderly seems to be most similar in Poland and Slovakia as well as Estonia, Latvia and Lithuania.     

Renewable enery-the path to sustainability

This article seeks to address some lingering debates within sustainability studies by revealing the connections between renewable energy,consumption and sustainability.Using data from 30 OECD countries,the article amines the connections via regression and geospatial analysis Findings from the quantitative analysis indicate that about 50% of the variation in sustainability is accounted for by the degree of renewables consumption.The geospatial analysis visually illustrates the intimate connections between the two variables.Theoreticallv,renewable energy,relates to sustainability in three dimensions.The first dimension is economic.Relying on traditional fossil fuels eventually will bring our economy to a stop.Renewable energies,however,are able to secure our energy supply into an indefinite future.The second dimension links to ethics.To leave an intact planet to future generations is a moral responsibility of our generation.The current energy supply system is built on depletion of natural resources,while the sources of renewable energy are vast and constantlv replenished The last dimension is ecologic.How to allocate a porper apportionment of the global hiosphere between humankind and the other life on the earth is a critical issue related to sustainability.By using renewable energv,we can greatly reduce our impact on biodiversity and therefore strike a balance between humankind and other life.Overall the research suggests that developing renewables can and in many cases does sustain a nation's economic growth while simultaneously protecting the environment.It is a win-win situation.This finding undoubtedly points out a practical and realistic path for sudtainable development.     

Monetary and fiscal policy interactions: Evidence from emerging European economies

This paper examines the interactions between fiscal and monetary policy for some former transition, emerging European economies over the 1995Q1–2010Q4 period by using a Markov regime-switching model. We consider the monetary policy rule proposed by Taylor (1993) and the fiscal policy rule suggested by Davig and Leeper (2007) in accounting for monetary and fiscal policy interactions. Empirical results suggest that monetary and fiscal policy rules exhibit switching properties between active and passive regimes and all countries followed both active and passive monetary policies. As for fiscal policy, the Czech Republic, Estonia, Hungary, and Slovenia seem to have alternated between active and passive fiscal regimes while fiscal policies of Poland and the Slovak Republic can be characterized by a single fiscal regime. Although the policy mix and the interactions between monetary and fiscal policy point a diverse picture in our sample countries, the monetary policy seems to be passive in all countries after 2000. This finding is consistent with the constraints imposed by European Union enlargement on monetary policy.     

The curse of natural resources in the transition economies*

The curse of natural resources is a well‐documented phenomenon for developing countries. Economies that are richly endowed with natural resources tend to grow slowly. Among the transition economies of the former ‘Eastern Bloc’, a similar pattern can be observed. This paper shows that a large part of the variation in growth rates among the transition economies can be attributed to the curse of natural resources. After controlling for numerous other factors, there is still a strong negative correlation between natural resource abundance and economic growth. Among the transition economies the prime reasons for the curse of natural resources were corruption and a neglect of basic education. In order to overcome the curse of natural resources and move to a sustainable path of development, the resource abundant transition countries should fight corruption and ensure that their resource revenues are invested in human capital or the preservation of natural capital.

Constitutions and the resource curse

Utilizing the fact that natural resources are randomly distributed among countries, we investigate how public income shocks have different long run economic effects dependent on constitutional arrangements. We find that (i) the so-called ‘resource curse’ is present in democratic presidential countries—but not in democratic parliamentary countries, (ii) being parliamentary or presidential matters more for the growth effects of natural resources than being democratic or autocratic, and (iii) natural resources are more likely to reduce growth when proportional electoral systems are in place than when the electoral systems are majoritarian. The two first effects appear very robust, the last effect less so.
