Environmental Performance in Socially Fragmented Countries

Social fragmentation is often associated with reduced co-operative behaviour, which undermines public goods provision (such as environmental protection). The few studies linking social fragmentation and environmental performance have been confined to using ethnic fractionalisation as the only measure of social heterogeneity. In this paper, we contribute to the literature in a twofold manner. First, we bring into the analysis alternative measures of social fragmentation (i.e. religious fractionalisation, ethnic/religious polarisation), that have received considerable attention in development economics in recent years. Second, this is the first study to our knowledge that makes use of a large panel dataset of several environmental indicators to explore links between ethnic/religious diversity and the environment. We find that all indices of social fragmentation are negatively linked to measures of environmental quality, although for some of them the size of the effect is larger in the case of polarisation.     

Italy’s decline and the balance-of-payments constraint: a multicountry analysis

According to the literature, the decline experienced by the Italian economy in the last two decades depends on a slowdown of its labour productivity, starting in the 1990s. The supply-side explanations of this slowdown are inconsistent with the major stylised facts. In this paper, we verify whether a better explanation is provided by the effect of a negative demand shock, through Italy’s external constraints, in the framework of Kaldor-Dixon-Thirlwall’s cumulative growth model. To this end, we use a multi-country generalisation of Thirlwall’s balance-of-payments-constrained growth model, which allows us to investigate the contribution of Italy’s main trade partners to Italy’s long-run growth from 1970 to 2010. The trade partners are disaggregated into seven groups: Eurozone core, Eurozone periphery, United States, other European countries, OPEC countries, BRIC, and the rest of the world. The results show that Italy’s long-run growth has been consistent with the Bop-constraint, that its decline can be explained by a progressive tightening of this constraint, that the sudden slowdown of labour productivity in the 1990s corresponds to a major shock on Italy’s external constraint, and that the major contributions to this shock came, through different channels of transmission, from the core Eurozone countries and from OPEC countries.     

Ethnicity, Politics and Economic Performance

The paper investigates the effects of ethnic diversity on economic performance. Previous studies have found that diversity has various detrimental microeconomic effects, tending to reduce public sector performance, and has large detrimental effects on the overall growth rate. I develop a simple model of the effect of ethnic diversity on a government decision problem in which there is a tradeoff between growth and distribution, in the contexts of democracy and dictatorship. I find that in democracy ethnic diversity has no effect upon the decision, whereas in dictatorship ethnic diversity leads to a government choice which reduces the growth rate. I then test these propositions on two data sets. The first is for 94 countries over the period 1960–1990. I find that whether diversity adversely affects overall economic growth depends upon the political environment. Diversity is highly damaging to growth in the context of limited political rights, but is not damaging in democracies. The second is for World Bank projects in 89 countries. I find that the same relationship between diversity and democracy affects the proportion of projects which are successful.     

Does violence against civilians depress voter turnout? Evidence from Bosnia and Herzegovina

We investigate the effect of violence against civilians on voting. Using data from elections in Bosnia and Herzegovina between 1990 and 2014 and exploiting variation in war intensity across municipalities, we estimate a negative impact on voter turnout. The effect is stable and persistent over twenty years after the war resolution. Our results are robust to the inclusion of pre- and post-war socioeconomic and political characteristics, to instrumental variable estimations based on terrain ruggedness, and to restricting the sample to voters who were too young to be selectively targeted. Distinguishing between civilian and military victims, we show that violence against civilians drives the negative effect. Next, we examine different mediating mechanisms including forced migration and demographic selection, ethnic composition, physical capital damage, post-conflict reconstruction, and labor market conditions. Our results support the hypothesis that violence affects voting through a “moral” dis-utility from showing allegiance to politics and the society by casting a vote. Using survey data, we show that respondents in more affected municipalities report lower generalized trust, trust in institutions, and voting.     

Capital flows and economic growth revisited: evidence from five Sub-Saharan African countries

The study examines the differential effects of capital flows on economic growth in five Sub-Saharan African (SSA) countries over the period 1970–2014. Using the autoregressive distributed lag methodology, the findings show that in the long-run capital flows (i.e. foreign direct investment (FDI), aid, external debt, and remittances) have different effects on economic growth. FDI has a significant positive effect in Burkina Faso and negative effects in Gabon and Niger whereas the impact of debt is negative in all countries. Aid, however, promotes growth in Niger and Gabon whiles it deters growth in Ghana. Remittances, on the other hand, have a significant positive effect in Senegal. Finally, gross capital formation is significant in most of the countries and the impact of trade is mixed. These results suggest that the benefits of capital flows in SSA have been overemphasized.     

Institutions of conflict management and economic growth revisited: a short note

We study the effects of institutions of conflict management like corporatism, trust, civic norms and group membership on economic growth. By employing Schneider and Wagner’s (Kyklos 54:509–532, 2001) model and data from 1990–2011, we show that corporatism has (still) a positive coordination effect and a negative rent-seeking effect. The total effect is positive for most countries.     

Estimates of gender differences in firm’s access to credit in Sub-Saharan Africa

Based on firm level data from 16 Sub-Saharan African countries we show how three different measures of credit constraints lead to three different estimates of gender differences in manufacturing firms’ credit situation. Using a perception based credit constraint measure female owned firms appear relatively more constrained than male owned firms. Using formal financial access data we find no gender effect. Finally, using direct information on credit constraints, male owned small firms appear disadvantaged. Furthermore we show a strong size gradient in the gender gap for the two measures for which we find significant gender differences.     

An endogenous growth model with embodied energy-saving technical change

In this paper, we extend the Romer [Journal of Political Economy 98 (Part 2) (1990) S271] model in two ways. First we include energy consumption of intermediates. Second, intermediates become heterogeneous due to endogenous energy-saving technical change. We show that the resulting model can still generate steady state growth, but the growth rate depends negatively on the growth of real energy prices. The reason is that real energy price rises will lower the profitability of using new intermediate goods, and hence, the profitability of doing research, and therefore have a negative impact on growth. We also show that the introduction of an energy tax that is recycled in the form of an R&D subsidy may increase growth. We conclude that in order to have energy efficiency growth and output growth under rising real energy prices, a combination of R&D and energy policy is called for.     

Not by growth alone: The role of the distribution of income in regional diversity in poverty reduction

This study examines the role of the distribution of income in determining the responsiveness of poverty to income growth and changes in income inequality using panel data of 58 developing countries for the period 1980-1998. We show that the large cross-regional variation in the capacity of income growth to reduce poverty, i.e. the income elasticity, is largely explained by differences in the initial distribution of income and present region and time specific estimates of the income and Gini elasticities of poverty. We find that the income elasticity of poverty in the mid-1990s equals −1.31 on average and ranges from −0.71 for Sub-Saharan Africa to −2.27 for the Middle East and North Africa, and that the Gini elasticity of poverty equals 0.80 on average and ranges from 0.01 in South Asia to 1.73 in Latin America. Furthermore we show that while differing income growth rates account for most of the regional diversity in poverty trends, the additional impact of differences across regions in rates of inequality change and income and inequality elasticities of poverty is almost always significant and far too large to be ignored, most notably so in Eastern Europe and Central Asia.     

The role of exports,FDI and imports in development: evidence from Sub-Saharan African countries

The disappointing economic performance of Sub-Saharan African (SSA) economies in the late 1980s prompted reforms in foreign trade and Foreign Direct Investment (FDI) in the early 1990s. Using the Autoregressive Distributed Lag (ARDL) approach and Pedroni panel estimation procedures that allow for heterogeneity, this study found that exports and FDI have a significant impact on economic growth. Granger-type causality tests show the interrelatedness of exports, FDI, imports and income variables. The results also provide evidence of a two-stage causal chain of exports, imports and income. This article calls for more market-oriented policy reforms in SSA countries.     

族群多样性与地方经济增长—来自中国城市层面的证据

族群多样性的经济影响及其发生机制,是经济学中一个方兴未艾的前沿研究领域.文章利用全国人口普查数据和抽样调查资料,构建了中国300多个城市族群多样性的面板数据,通过计量分析发现,高的族群多样性显著降低了地方经济增长率.在考察了测量指标的影响和内生性问题后,结论依然稳健.通过对影响机制的探讨,文章发现:高的族群多样性显著增大了语言沟通成本,降低了私有部门投资率;另一方面,公有部门投资率不受族群多样性的影响,人均中央财政转移支付和族群多样性显著正相关,这两者缓解了族群多样性的不利影响.以上发现,一方面为族群多样性经济影响的研究提供了新的实证证据;另一方面也为中国地方经济增长的差异性提供了一个新的解释,并衍生出新的学术课题和政策意涵.     

汇率升值经济效应的经验研究

本文分析了美元、日元与人民币升值的经济效应,从历史经验来看,实际汇率升值常常导致出口下滑、经济增长率下降,但不同的升值背景所导致的结果并不完全相同.80年代初的美元汇率升值对美国经常账户影响较大;1985年之后的日元汇率升值对日元经常账户影响不大,但日元升值连同不当的货币政策对日本形成很大打击,其主要负面效应是产业空心化以及资产泡沫;1994年至1997年人民币实际汇率升值的背景是国内需求旺盛、全球经济增长强劲,升值所导致的负面效应不够明显.除了历史经验之外,本文还回顾了实证文献对汇率升值经济效应的研究     

Do National Numerical Fiscal Rules really shape fiscal behaviours in developing countries? A treatment effect evaluation

This paper analyses the effect of National Numerical Fiscal Rules (FRs) upon fiscal discipline in 74 developing countries over the period 1990–2007. It is the first study that assesses the impact of FRs on budgetary outcomes while controlling for the self-selection problem. It finds that the effect of FRs on structural fiscal balance is significantly positive, robust to a variety of alternative specifications, and varies with the type of FRs. It also finds that the treatment effect differs according to countries' characteristics: number of FRs, time length since FRs adoption, presence of supranational FRs, government fractionalisation and government stability.     

Diversity and innovation

Although the effect of culture on national innovation levels is well-established, previous literature assumes cultural homogeneity within a nation. In this article we analyse two aspects of diversity – ethnic and values – and their impact on national innovation output. We show that ethnic diversity or fractionalization and values diversity are distinct and while the former has a negative effect on innovation, the latter contributes positively. However, countries are bound to have both types of diversity. We find that countries that are ethnically homogenous but diverse in values orientation are the best innovators.     

Unwrapping some euro area growth puzzles: Factor substitution, productivity and unemployment

In this paper, we estimate a long run supply-side system incorporating a CES production function with time-varying factor-augmenting technical progress for the euro area over the period 1970–2005. We find that the elasticity of substitution lies below unity at 0.7, that labor-augmenting technical progress is dominant in the long run while capital-augmenting technical progress plays an important role in the interim period. Importantly, we also find evidence of a structural break in the pattern of biased technical progress towards the end of the 1990s. Our results help to solve two puzzles in Europe’s recent growth experience which differ markedly from the US experience. The first is related to the effects of the IT boom in the 1990s on productivity growth in Europe. The second puzzle concerns the changes in the “Okun’s law” relationship, linking growth to the reduction of unemployment, which are observable in Europe since the late 1990s.     

The Economic Cost of Gender Gaps in Effective Labor: Africa's Missing Growth Reserve

This study analyzes the impact of the gender gap in effective labor – defined as the combined effect of the gender gaps in labor force participation and education – on economic output per worker. The results indicate that the gender gap in effective labor has a negative effect on the economic output per worker in African countries. A 1 percent increase in the gender gap in effective labor leads to a reduction in output per worker by 0.43–0.49 percent in Africa overall, 0.29–0.50 percent in Sub-Saharan Africa, and 0.26–0.32 percent in a wider group of countries from Africa and Asia. The total annual economic losses due to gender gaps in effective labor could be as high as US$255 billion for the African region. Results confirm that Africa is missing its full growth potential because a sizeable portion of its growth reserve – women – is not fully utilized.     

Gender Effects of Trade Openness in Sub-Saharan Africa

ABSTRACT

More than thirty years into the modern era of globalization, scholars are now in a position to evaluate the distributive effects of the policy shifts that have led to greater economic integration. One region of the world for which little robust empirical evidence exists on gendered employment effects is Sub-Saharan Africa (SSA). To identify whether there is an impact of economic and trade structure on women's relative access to work, this contribution empirically explores these issues for thirty-eight SSA countries, and for two subgroups. Panel data for the period 1991–2010 is examined using fixed effects, random effects and two-stage least-squares estimation techniques. Findings suggest that trade liberalization has gendered employment effects, with the direction depending on the structure of the economy. However, the more robust finding is that a country's infrastructure has played a determining role in gendered labor market outcomes in SSA since the early 1990s.     

The export-output growth nexus in Japan: a bootstrap rolling window approach

The purpose of this article is to examine the export–output nexus in Japan by taking into account the time variation in the causal link with bootstrap Granger non-causality test and rolling estimation. The data used cover the seasonally adjusted real export and real Gross Domestic Product (GDP) for the 1957:1–2009:1 period. Standard Granger causality tests indicate no causality between export and real GDP series. On the contrary, full sample-modified Granger causality tests based on bootstrap, which are applicable irrespective of integration–cointegration properties of the data, indicate a bi-directional causal link between exports and real GDP. Accordingly, export growth should be an important factor behind Japan’s high-economic growth in the last three decades. Using parameter stability tests, we show that these results are not uniform for different sample periods and results vary due to structural changes. Using bootstrap rolling window estimation, we find that there is a positive bi-directional predictive power from the mid 1970s to the late-1980s between the series, while from the late 1990s to 2009 there is a positive predictive power only from export growth to output growth.     

Effects of financial liberalization on financial market development and economic performance of the SSA region: An empirical assessment

This study investigates the role of financial liberalization in promoting financial deepening and economic growth in Sub-Saharan African countries (SSA). We apply the more efficient system GMM estimator in dynamic panel data that combines first difference and original level specification to deal with the problems of weak instruments. Our dataset covers 21 countries in Sub-Saharan Africa over the period of 1981–2009.Additionally, the paper sought to examine both the direct and indirect impacts of financial liberalization policies on economic growth and financial deepening using a much more comprehensive and recent financial liberalization dataset. The econometric results suggest that, on average, financial liberalization is negatively associated with income growth in SSA region. Our findings provide support for the skeptical empirical view of financial liberalization in emerging markets, which show that liberalization, by itself, might be associated with lower economic growth through leading to destabilization, stimulating domestic capital flight and increasing the risk of financial fragility. However, the research finds that financial liberalization does indeed impact positively on financial deepening and resource mobilization in SSA region, after controlling for key macroeconomic factors such as institutional quality, fiscal imbalances and inflation. In fact the study reports a stronger reforms effect for countries that have stronger legal institutions, protection of property rights and higher human capital. Policy-wise, the study finds that institutional and human capital factors are important in explaining growth and financial development; therefore, it is necessary for SSA governments to promote a stronger and more transparent institutional development as we move forward.     

Multivariate filter estimation and ARDL model analysis of China’s potential output

In this article, we apply a new multivariate filter approach to estimate China’s potential output. Furthermore, we build an ARDL model to analyse the influence on potential growth caused by important factors that contribute to estimation and China’s development. Our results show that the current economic slowdown is not a cyclical phenomenon and China’s potential growth has declined since 2010. We also show that fixed asset investment and trade, which have a long-run relationship with potential output, exert negative long-run effect on potential growth justifying the implementation of China’s recent supply-side reforms.
