democracy and economic growth a meta analysis despite a sizeable theoretical and empirical literature no firm conclusions have been drawn regarding the impact of political democracy on economic growth this article challenges the consensus of an inconclusive relationship through a quantitative assessment of the democracy growth literature it applies meta regression analysis to the population of 483 estimates derived from 84 studies on democracy and growth using traditional meta analysis estimators the bootstrap and fixed and random effects meta regression models it derives several robust conclusions taking all the available published evidence together it concludes that democracy does not have a direct impact on economic growth however democracy has robust significant and positive indirect effects through higher human capital lower inflation lower political instability and higher levels of economic freedom democracies may also be associated with larger governments and less free international trade there also appear to be country and region specific democracy growth effects overall democracy s net effect on the economy does not seem to be detrimental

from physical to human capital accumulation inequality and the process of development this paper develops a growth theory that captures the replacement of physical capital accumulation by human capital accumulation as a prime engine of growth along the process of development it argues that the positive impact of inequality on the growth process was reversed in this process in early stages of the industrial revolution when physical capital accumulation was the prime source of growth inequality stimulated development by channelling resources towards individuals with a higher propensity to save as human capital emerged as a growth engine equality alleviated adverse effects of credit constraints on human capital accumulation stimulating the growth process this research develops a growth theory that captures the endogenous replacement of physical capital accumulation by human capital accumulation as a prime engine of economic growth in the transition from the industrial revolution to modern growth the proposed theory offers a unified account for the effect of income inequality on the growth process during this transition it argues that the replacement of physical capital accumulation by human capital accumulation as a prime engine of economic growth changed the qualitative impact of inequality on the process of development in the early stages of the industrial revolution when physical capital accumulation was the prime source of economic growth inequality enhanced the process of development by channelling resources towards individuals whose marginal propensity to save is higher in the later stages of the transition to modern growth as human capital emerged as a prime engine of economic growth equality alleviated the adverse effect of credit constraints on human capital accumulation and stimulated the growth process the proposed theory unifies two fundamental approaches regarding the effect of income distribution on the process of development the classical approach and the credit market imperfection approach 1 the classical approach was originated by smith 1776 and was further interpreted and developed by keynes 1920 lewis 1954 kaldor 1957 and bourguignon 1981 according to this approach saving rates are an increasing function of wealth and inequality therefore channels resources towards individuals whose marginal propensity to save 1 the socio political economy approach provides an alternative mechanism equality diminishes the tendency for socio political instability or distortionary redistribution and hence it stimulates investment and economic growth see the comprehensive survey of benabou 1996b

a meta analytic reassessment of the effects of inequality on growth this paper develops a meta analysis of the empirical literature that estimates the effect of inequality on growth it covers studies published in scientific journals during 1994 2014 that examine the impact on growth of inequality in income land and human capital distribution we find traces of publication bias in this literature as authors and journals are more willing to report and publish statistically significant findings and the results tend to follow a predictable time pattern over time according to which negative and positive effects are cyclically reported after correcting for these two forms of publication bias we conclude that the high degree of heterogeneity of the reported effect sizes is explained by study conditions namely the structure of the data the type of countries included in the sample the inclusion of regional dummies the concept of inequality and the definition of income in particular our meta regression analysis suggests that cross section studies systematically report a stronger negative impact than panel data studies the effect of inequality on growth is negative and more pronounced in less developed countries than in rich countries the inclusion of regional dummies in the growth regression of the primary studies considerably weakens such effect expenditure and gross income inequality tend to lead to different estimates of the effect size land and human inequality are more pernicious to subsequent growth than income inequality is we also find that the estimation technique the quality of data on income distribution and the specification of the growth regression do not significantly influence the estimation of the effect sizes these results provide new insights into the nature of the inequality growth relationship and offer important guidelines for policy makers

inequality and city size between 1979 and 2007 a strong positive monotonic relationship between wage inequality and city size has developed this paper investigates the links between this emergent city size inequality premium and the contemporaneous nationwide increase in wage inequality after controlling for the skill composition of the workforce across cities of different sizes we show that at least 23 percent of the overall increase in the variance of log hourly wages in the united states from 1979 to 2007 is explained by the more rapid growth in the variance of log wages in larger locations relative to smaller locations this influence occurred throughout the wage distribution and was most prevalent during the 1990s more rapid growth in within skill group inequality in larger cities has been by far the most important force driving these city size specific patterns in the data differences in the industrial composition of cities of different sizes explain up to one third of this city size effect these results suggest an important role for agglomeration economies in generating changes in the wage structure during the study period

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

central city crime and suburban economic growth this paper explores the relationship between inner city crime patterns and suburban income growth analysing data on 318 us counties for selected metropolitan statistical areas of 32 states within the united states from 1982 to 1997 the findings suggest that violent crime does seem to have a negative impact on close in suburbs with a less negative impact farther away from the central city becoming positive at some point while results are not as robust as we had hoped they are consistent with flight to further out suburbs rather than migration to different metropolitan areas in response to urban crime

valuing rail access using transport innovations this paper uses a powerful empirical method to evaluate the benefits of rail access to consumers we study the effects on house prices of a transport innovation that altered the distance to the nearest station for some households but left others unaffected the transport innovation we study is the construction of new stations in london in the late 1990s using this innovation we implement a quasi experimental approach that allows us to avoid the biases inherent in cross sectional valuation work our evidence on distance station effects on local prices identified through distance changes induced by the transport innovation suggests that households value rail access and that these valuations are large compared to the valuations of other local amenities

migration of professionals from fiji to new zealand a reduced form supply demand model abstract in this study we estimate a reduced form equation for migration of highly skilled and professionally trained workers from fiji to new zealand during 1987 1990 explanatory variables include previous period s migrants occupational income in new zealand the supply of graduates in new zealand and political instability in fiji using a reduced form supply demand model to estimate the determinants of migration the study finds that the number of professional migrants from fiji was significantly and positively related to previous year s migrants the real income in new zealand and political instability in fiji

inequality credit and financial crises in the three decades leading up to the financial crisis of 2008 09 income inequality rose across much of the developed world this has led to a vigorous debate as to whether widening inequality was somehow to blame for the crisis by driving private sector credit booms despite growing interest empirical evidence on an inequality fragility relationship is limited based on a panel analysis of 18 oecd organisation for economic co operation and development countries for the years 1970 2007 this study provides evidence of a positive relationship between income concentration and private sector indebtedness once other traditional drivers are controlled for if confirmed the implications of this result are as follows i the view that the distribution of income is irrelevant to macroeconomic stability as implicit in mainstream approaches needs further investigation and ii in order to make the financial system more robust policy makers should cast the net wider than monetary policy and regulatory reforms and consider the effects of changes to distributive patterns

inequality and growth in the united states evidence from a new state level panel of income inequality measures i introduction rising income inequality in the united states over the past quarter century is well documented see e g gottschalk 1997 krueger 2003 levy and murnane 1992 piketty and saez 2003 whether and by how much this change in inequality is associated with a change in economic performance is an important question yet recent empirical work has been largely inconclusive positive relationships between income inequality and economic growth have been found by partridge 1997 2005 using a panel of states and by forbes 2000 using a panel of countries empirical work by panizza 2002 and quah 2001 however has found little or no stable relationship between inequality and growth the results appear to be extremely sensitive to the econometric specification additionally barro 2000 has found evidence that the relationship is nonlinear with inequality being positively related to growth among wealthier countries like the united states but negatively related to growth among low income countries much of this recent empirical literature was initiated by the important work of deininger and squire 1996 who constructed a large cross national panel of inequality measures containing several time series observations for each nation spaced over multiple decades a parallel empirical literature also emerged using u s state level data with income inequality measures typically spaced at 10 yr intervals see e g panizza 2002 partridge 1997 2005 both the state level and the cross national empirical literatures benefited by exploiting the more advanced panel data econometrics afforded by the large n small t panel dimensions in this paper we offer a new more comprehensive panel of state level income inequality measures and use this panel to reevaluate the empirical inequality growth relationship 1 this panel has the unique feature of being large in both n and t with annual observations of the 48 contiguous states for the entirety of the postwar period 1945 2004 for nearly all the states in the panel the share of income held by the top decile experienced a prolonged period of stability after world war ii followed by a substantial increase during the 1980s and 1990s these state level trends appear to closely replicate the overall trends in aggregate u s inequality found by piketty and saez 2003 exploiting the large and balanced size of our inequality panel we explore the long run relationship between inequality and growth via three alternative dynamic panel error correction estimators the fixed effects fe estimator the mean group mg estimator of pesaran and smith 1995 and the pooled mg estimator of pesaran shin and smith 1999 the greater homogeneity of state level data helps mitigate the difficulty in adequately capturing structural differences across international panels of earlier studies such as forbes 2000 and barro 2000 corruption levels labor market flexibility tax neutrality tradition of entrepreneurship and many other factors are only poorly measured if at all barro 2000 1011 and these sources of heterogeneity are much more likely to contribute to omitted variable bias across countries than across states the results from our analysis indicate that the long run relationship between the top decile share of income and economic growth is positive in nature moreover an evaluation of several alternative income inequality measures suggests that this positive relationship is driven primarily by the concentration of income in the upper end of the income distribution the structure of the paper is as follows section ii presents the new panel of annual state level inequality measures and includes an important discussion of its key limitations section iii then offers an empirical investigation on the impact of income inequality on the growth rate of real income per capita finally section iv offers a brief set of conclusions

economic growth size of the agricultural sector and urbanization in africa this paper uses variations in international commodity prices and rainfall to construct instrumental variables estimates of the within country effect that changes in the size of the agricultural sector and gdp per capita growth have on the urbanization rate for a panel of 41 african countries during the period 1960 2007 the paper s three main findings are that i decreases in the share of agricultural value added lead to a significant increase in the urbanization rate ii conditional on changes in the share of agricultural value added gdp per capita growth does not significantly affect the urbanization rate iii increases in the urbanization rate had a significant negative average effect on gdp per capita growth

is income inequality harmful for regional growth evidence from the european union this article examines the relationship between income inequality and economic growth in the regions of several european union countries over the period 1993 2002 using the information provided by the european community household panel taking into consideration the relevance of spatial effects in this context different versions of a spatial econometric model are estimated the results indicate that the degree of income dispersion is negatively associated with regional growth this finding is in fact robust to various alternative specifications including a number of additional explanatory variables such as initial per capita gdp the sectoral composition of economic activity human capital stock population density and market potential furthermore the observed negative correlation between income inequality and economic performance does not depend on the specific measure used to quantify the degree of income dispersion

valuing school quality better transport and lower crime evidence from house prices housing prices within urban areas exhibit highly localized variation that cannot be explained solely by differences in the physical attributes of dwellings we consider the role of local amenities and disamenities in generating price variation within urban areas focusing on three highly policy relevant urban issues transport accessibility school quality and crime our survey of the recent empirical literature highlights what is known and what is not known on these issues and considers the relevance and reliability of this evidence for policy design and evaluation although there are serious empirical challenges we argue that research on housing values based on careful research designs can offer credible estimates of the social value of place specific attributes and amenities

inequality and growth uncovering the main conclusions from the empirics abstractthis paper is a critical survey of the empirical literature on the effects of inequality on economic growth we conclude that it is most likely that the disparities found in the results are due to differences in the type of countries and time periods included in the samples the variable used to measure inequality the structure of the data and the estimation techniques these findings suggest that the mechanisms that link inequality to growth are likely to operate differently in different circumstances an element that may offer important guidelines for both policy makers and researchers

the short run relationship between inequality and growth evidence from oecd regions during the great recession abstractthis paper provides evidence on the relationship between income inequality and economic growth in organisation for economic co operation and development oecd regions during the decade 2003 13 it combines household survey data and macroeconomic databases covering over 200 comparable regions in 15 oecd countries the econometric results based on two alternative sets of instruments highlight a general negative association between inequalities and economic growth since the start of the economic crisis this relationship is sensitive to the type of urban structure higher inequalities seem to be more detrimental for growth in regions characterized by medium to large sized cities while regions characterized by small cities and rural areas are less affected

inequality does cause underdevelopment insights from a new instrument consistent with the provocative hypothesis of engerman and sokoloff 1997 2000 this paper confirms with cross country data that agricultural endowments predict inequality and inequality predicts development the use of agricultural endowments specifically the abundance of land suitable for growing wheat relative to that suitable for growing sugarcane as an instrument for inequality is this paper s approach to problems of measurement and endogeneity of inequality the paper finds inequality also affects other development outcomes institutions and schooling which the literature has emphasized as mechanisms by which higher inequality lowers per capita income it tests the inequality hypothesis for development institutional quality and schooling against other recent hypotheses in the literature while finding some evidence consistent with other development fundamentals the paper finds high inequality to independently be a large and statistically significant barrier to prosperity good quality institutions and high schooling

on the simultaneity problem in the aid and growth debate this paper shows that foreign aid has a significant positive average effect on real per capita gross domestic product gdp growth if and only if the quantitatively large negative reverse causal effect of per capita gdp growth on foreign aid is adjusted for in the growth regression instrumental variables estimates show that a 1 percentage point increase in gdp per capita growth decreased foreign aid by over 4 adjusting for this quantitatively large negative reverse causal effect of economic growth on foreign aid shows that a 1 increase in foreign aid increased real per capita gdp growth by around 0 1 percentage points

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

factor costs and factor use substitution among urban land and capital inputs in the production of single family housing this paper uses cost functions to test the hypothesis of constancy of the elasticity of substitution among land and capital inputs in the production of single family housing the findings suggest that the substitution parameter varies over the range of the sample the hypothesis of homotheticity in the production is also rejected this implies that the ces and cobb douglas production functions are not suitable for urban housing production modelling the analysis has been carried out by imposing much weaker restrictions as a part of the maintained hypotheses than has been the case in the recent literature

the effects of a new subway line on housing prices in metropolitan toronto an analysis by means of using the estimation results of a modal choice model and the hedonic price regressions model is conducted in order to identify the effects of a subway line in toronto on the values of housing units the modal choice model is used for the estimation of the direct benefits from the improvement in transportation and the hedonic price equations for the identification of subway effects on housing prices empirical results indicate that the direct savings in commuting costs have been capitalized into housing values
