What drives the cross‐country growth and inequality correlation?

Abstract.  We present a neo‐classical model that explores the determinants of growth‐inequality correlation and attempts to reconcile the seemingly conflicting evidence on the nature of the growth‐inequality relationship. The initial distribution of human capital determines the long‐run income distribution and the growth rate by influencing the occupational choice of the agents. The steady‐state proportion of adults that innovates and updates human capital is path dependent. The output elasticity of skilled‐labour, barriers to knowledge spillovers, and the degree of redistribution determine the range of steady‐state equilibria. From a calibration experiment we report that a skill‐intensive technology, low barriers to knowledge spillovers, and high degrees of redistribution characterize the industrial countries with a positive growth‐inequality correlation. A negative correlation between growth and inequality arises for the group of non‐industrial countries with the opposite characteristics. JEL classification: E1, O4     

Time–frequency relationship between US inflation and inflation uncertainty: evidence from historical data

We provide new evidence on the relationship between inflation and its uncertainty in the United States on an historical basis, covering the period from 1775 to 2014. First, we use a bounded approach for measuring inflation uncertainty, as proposed by Chan et al. (2013), and compare the results with the Stock and Watson (2007) and Chan (2015) methods. Second, we employ the wavelet methodology to analyze the comovements and causal effects between the two series. Our results provide evidence of a relationship between inflation and its uncertainty that varies across time and frequency. First, we show that in the medium and long runs, the Freidman–Ball hypothesis holds with a bounded measure of uncertainty, while if the Stock and Watson (2007) measure of uncertainty is used, the Cukierman–Meltzer reasoning prevails. Therefore, the findings are sensitive to the way inflation uncertainty is computed. Second, we discover mixed evidence about the inflation–uncertainty nexus in the short run, findings that explain the mixed results reported to date in the empirical literature.     

The relationship between saving and finance: theory and evidence from E.U. countries

This paper investigates the relationship between saving and investment in an effort to shed light on the issue of mobility of capital and whether or not this is prevented by the presence of any barriers. The data of our analysis are annual and come from 14 E.U. countries during the 1960–1994 period. The econometric analysis shows that for the E.U. countries, saving and the provision of credit are two cointegrated variables, which means that for each E.U. country (Belgium was the only exception) the amount of money saved is closely related to the amount of money that is ultimately invested. This result lends support to the view that in E.U. countries the degree of capital mobility plays a minor role in investment, which is primarily influenced by the conditions affecting the domestic provision of savings. In addition, the econometric analysis shows that the causal linkage is in most countries from savings to investment.     

Hub‐and‐spoke free trade areas: theory and evidence from Israel

Abstract We study how the sequential formation of free trade areas affects trade flows between member countries. In a three‐country, three‐good model of comparative advantage if two countries have an FTA, and both sign a similar agreement with the third, trade between the two decreases. However, if only one of them signs an additional FTA, a hub‐ and‐spoke pattern arises, and trade between the initial members increases. Israel’s experience lends strong support to our model: trade between Israel and the EU, subject to an FTA since 1975, increased by an additional 29% after the introduction of the US‐Israel FTA in 1985.     

Income inequality and FDI: evidence with Turkish data

This article explores how foreign direct investment (FDI) and other determinants impact income inequality in Turkey in the short- and long-run. We apply the nonlinear auto-regressive distributed lag (ARDL) modelling approach, which is suitable for small samples. The data for the study cover the years from 1970 to 2008. The empirical results indicate the existence of a co-integration relationship among the variables with asymmetric adjustment of the income distribution in the short- and long-run. The negative impact of FDI on the Gini coefficient, decreasing income inequality, is statistically significant in the short- and long-run, though with a quantitatively small impact in both cases. In the short run, GDP growth increases inequality initially, an effect that is reversed in the next period, increases in domestic gross capital formation decreases inequality, and increases in the literacy rate have very minor adverse effects on income equality. However, in the long run these variables have no statistically significant effects on the Gini coefficient. A reduction in the population growth rate reduces inequality in the short run but has no effect in the long run, whereas an increase in the rate reduces inequality in the long run but has no effect in the short run.     

Income convergence among U.S. states: cross‐sectional and time series evidence

We perform convergence tests on the U.S. states for per capita income from 1930 to 2009. Cross‐sectional tests support overall σ‐convergence and β‐convergence but may not hold true for the last three decades. Time series tests suggest that about half of the states exhibit stochastic convergence and of these all are also β‐converging. Probit regressions reveal that the likelihood a state is converging is a function of changing capital to labour ratios, the size of the agricultural sector, and levels of taxation and tax revenue. Regional disparities in convergence remain among the southern and midwestern states.     

投资与通货膨胀-紧缩的联系:来自中国的经验证据

基于Toda-Yamamoto长期因果检验程序和广义脉冲反应技术,本文首先研究了全社会实际固定资产投资与零售价格水平变动之间的长期因果及其冲击-动态反应关系,然后进一步考察了货币供给量M1和贸易依存度在促成上述关系中所扮演的角色.其研究结论为:(1)货币供给量M1是唯一的外生变量,其增长不是价格水平变动的直接因,而是通过全社会实际固定资产投资间接地成为价格水平变动的因;(2)贸易依存度和全社会实际固定资产投资之间存在双向因果联系,前者只能通过后者间接地成为价格水平变动的因;(3)中国对外开放既消化又强化了中国生产能力过剩,但消化胜于强化;(4)投资一个单位正向冲击在开始的2-4年左右导致相对温和的通货膨胀,但后五年左右将导致相对严重的通货紧缩.     

The relationship between inflation and its variability: International evidence from the 1970s

This paper reexamines the empirical relationship between the average level of inflation and its variability. Based on a sample of 40 diverse economies, our results suggest that no one group of countries was able to avoid the decreased inflation predictability associated with higher levels of inflation during the 1970s. In contrast, previous research showed that Highly Industrialized countries, as a group, were able to control inflation variability during the period 1950–1970. Our results also suggest that the “threshold” level of inflation appears to have risen substantially during the 1970s. Whereas previous research suggested an upper bound of the threshold at about a four percent rate of inflation, the evidence from the 1970s indicates that the threshold may have risen to about a nine percent inflation rate.     

The Relationship Between Saving and Credit from a Schumpeterian Perspective

After 1995, the United States experienced housing and mortgage booms, fuelled by increased lending from less regulated institutions, such as hedge funds. At the micro level, the housing boom may have left families with more wealth, but the mortgage boom may have increased their financial vulnerability. Using the Federal Reserve’s Survey of Consumer Finances, we consider both wealth creation and a select number of financial vulnerability measures of homeowners. The data indicate that the housing boom was not only associated with larger house values, but also moderated wealth gains and substantially greater financial vulnerability of homeowners. Both trends were more pronounced among middleincome and Hispanic families, who saw larger wealth gains, but also greater increases in financial vulnerability than their counterparts. Given the breadth of the spread in homeowners’ financial vulnerability alongside sharply higher house prices, our results support the link between more deregulated financial markets and rising financial instability.     

Schumpeterian patterns of innovation and the sources of breakthrough inventions: evidence from a data-set of R&D awards

This paper examines the relationship between Schumpeterian patterns of innovation and the generation of breakthrough inventions. Our data source for breakthrough inventions is the “R&D 100 awards” competition organized each year by the magazine Research & Development. Since 1963, this magazine has been awarding this prize to 100 most technologically significant new products available for sale or licensing in the year preceding the judgment. We use USPTO patent data to measure the relevant dimensions of the technological regime prevailing in each sector and, on this basis, we provide a characterization of each sector in terms of the Schumpeter Mark I/Schumpeter Mark II archetypes. Our main finding is that breakthrough inventions are more likely to emerge in ‘turbulent’ Schumpeter Mark I type of contexts.     

Relationships between corruption,political orientation,and income inequality: evidence from Latin America

This research sheds light on the analysis of the impact of corruption and political orientation on income distribution in Latin America. Although it has been theoretically demonstrated that corruption worsens the income distribution, the empirical evidence has yielded ambiguous results based on biased estimates not considering a measurement error in the estimation of inequality. This article fills this gap by correcting the previous measurement error bias in the fixed-effects estimation. Additionally, political orientation and its relationship with income inequality are also investigated. The sample covers 18 Latin American countries between 1996 and 2012. Results reveal that corruption increases income inequality.     

Trade efficiency and economic development: evidence from a cross country comparison

Economic theory suggests that development is enhanced through income growth, which is driven through increased trade. However, the empirical evidence of such a relationship most of the times is proved to be weak. In this study we try to determine the factors influencing this relationship by measuring ‘trade efficiency’. Using the data envelopment analysis (DEA) window method for a sample of 16 OECD countries, we obtained the efficiency scores and the optimal output levels for the inefficient countries for a time period of 5 years under consideration. Results drawn from the broadly used ratio analysis were also compared to the results derived from the DEA model. Our empirical findings show that ‘trade efficient’ countries have clear characteristics like low-exchange rates for exports, low R&D intensity, high-value intra industry trade and positive impact of net trade on their gross domestic product.     

The relationship between total factor productivity growth and employment: some evidence from a sample of European Regions

This paper provides a structural estimation of an equilibrium matching model with exogenous productivity growth on a sample of European Regions for the period 1976–2000. Using a three-stage least squares procedure, I estimate a simultaneous equation model for employment, wages and capital stock. The importance of the study of the relationship between growth and employment is due to the fact that the sign of this connection is not clear-cut. Theoretical models imply that the impact of productivity on employment is ambiguous. Furthermore, the empirical contributions are still not so many to reach a strong conclusion on the sign of the relationship above. This paper finds that the impact of productivity growth on employment is negative in the short-run and this effect remains negative even in the long-run. The implication of my results is that all new technology is embodied in new jobs and job creation plays no role in the employment dynamics of the sample I have considered.     

Willingness‐to‐pay for parallel private health insurance: evidence from a laboratory experiment

Abstract Debate over the effects of public versus private health care finance persists in both academic and policy circles. This paper presents the results of a revealed preference laboratory experiment that tests how characteristics of the public health system affect a subject's willingness‐to‐pay (WTP) for parallel private health insurance. Consistent with the theoretical predictions of Cuff et al. (2010), subjects’ average WTP is lower and the size of the private insurance sector smaller when the public system allocates health care based on need rather than randomly and when the probability of receiving health care from the public system is high.     

Local inequality and project choice: Theory and evidence from Ecuador

This paper provides evidence consistent with elite capture of Social Fund investment projects in Ecuador. Exploiting a unique combination of data sets on village-level income distributions, Social Fund project administration, and province-level electoral results, we test a simple model of project choice when local political power is unequally distributed. In accordance with the predictions of the model, poorer villages are more likely to receive projects that provide excludable (private) goods to the poor, such as latrines. Controlling for poverty, more unequal communities are less likely to receive such projects. Consistent with the hypothesis of elite capture, these results are sensitive to the specific measures of inequality and elite power used in the empirical analysis, and are strongest for expenditure shares at the top of the distribution.     

Wealth inequality and credit markets: evidence from three industrialized countries

Economic theory predicts that changes in the distribution of wealth in an economy affect real interest rates if capital markets are imperfect. We investigate this link for the US, the UK, and Sweden, using multivariate time series analysis that explicitly allows for feedback effects between wealth inequality and real interest rates. Our estimates yield that, over the course of the twentieth century, decreases in wealth inequality led to significant declines in real interest rates. Our results therefore point to the importance of capital market imperfections that arise from moral hazard. They put to question the empirical relevance of a negative interest rate effect of inequality that may arise in variants of these models with high inequality, heterogeneous agents or adverse selection.     

R&D spillovers and employment: evidence from European patent data

In this paper we investigate the role of patents in the relationship between R&D activity, spillovers and employment at the firm level. A reduced-form labour demand equation is estimated. Our analysis is based upon a dataset consisting of 879 R&D-intensive manufacturing firms worldwide for which information was collected for the period 2002–2010. We use data from all EU R&D investment scoreboard editions issued every year until 2011 by the JRC-IPTS (scoreboards). Since the innovation output of the industrial strategy of every firm is the number of patents, the main contribution to the existing literature is to investigate also the impact of patents/R&D ratio and patents/spillovers ratio on employment level. The empirical results suggest a significant impact of R&D spillover effects on company employment although the results differ substantially according to the spillover stock, which may considerably affect policy implications.     

The effect of reporting errors on the cross-country relationship between inequality and crime

This paper analyzes reporting errors in crime data to see how they impact econometric estimates, particularly of the key relationship between inequality and crime. Criminal victimization surveys of 140,000 respondents in 37 industrial, transition and developing countries are used. Comparing the crimes experienced by these respondents with those reported to the police, non-random and mean-reverting errors are apparent. Time-varying factors affect the propensity of victims to report crimes to the police, undermining the use of country-specific fixed effects as a means of dealing with measurement error in official crime data. These errors substantially attenuate both cross-sectional and panel estimates of the partial correlation between inequality and crime.     

Exchange rates,market structure and price-cost margins: evidence from a developing country

This paper analyses the sensitivity of firm performance to exchange rate fluctuations. In a two-country world, consisting of a developing domestic country and a developed foreign country, we show that this sensitivity is closely related with market structure and the share of imported inputs in total cost. When the share of imported inputs is low, depreciation leads to an increase in price cost margin. This increase intensifies in more competitive industries. When the imported input share is high, the price cost margin may decrease as a result of depreciation, and this effect becomes pronounced in more competitive industries. The empirical test where we used 3-digit Turkish Manufacturing industry data support most of the findings of our model.     

The causal relationship between natural gas consumption and economic growth: evidence from the G7 countries

This article re-examines the nature of the causality between natural gas consumption and economic growth in G7 countries over the period from 1965 to 2011. We employ the Granger causality procedure proposed by Emirmahmutoglu and Kose (2011) which takes into account cross-sectional dependency and heterogeneity across countries. Our overall empirical results support the neutrality hypothesis for the panel while the individual country results confirm the same result with the exception of the case of UK, where the conservation hypothesis is confirmed, showing that GDP causes natural gas consumption in the country. These results make policies that promote the consumption of natural gas risk-free with regard to their effects to the economic growth and development levels.
