The link between economic growth and growth volatility

This paper investigates the relationship between economic growth and growth volatility through simultaneous equations system. By employing the identification through heteroskedasticity method of Rigobon (Rev Econ Stat 85:777–792, 2003) and using a panel of 158 countries over the period 1960–2010, we find that output volatility is detrimental to economic growth, suggesting that stabilization policies to mitigate short-run economic fluctuations contribute to long-run economic growth. And economic growth accelerates output variability, supporting the feedback effects from growth to the volatility. The evidence is robust to a number of sensitivity tests.     

Level of economic development and political democracy revisited

This article reassesses a democracy-economic development linkage for the period 1972 to 1990. The results show that economic development has a significant effect on democratic performance in the semiperiphery and periphery, yet in an opposite direction. For the core, there is no linkage from economic development to political performance. Moreover, the finding also suggests that democracy enhances economic development only in the core and semiperiphery. This finding thus contradicts Barro's [1996] contention that more democracy enhances economic growth at low levels of political freedom, but it depresses economic growth when a moderate level of freedom has already been attained.     

Political institutions and economic volatility

We examine the effect of political ‘institutions’ on economic growth volatility, using data from more than 100 countries over the period 1960 to 2005, taking into account various control variables as suggested in previous studies. Our indicator of volatility is the relative standard deviation of the growth rate of GDP per capita. The results of a dynamic panel model indicate that democracy reduces economic volatility. We also find that some dimensions of political instability and policy uncertainty increase economic volatility.     

Output volatility and economic growth

This paper proposes a new instrument to identify the causal effect of output volatility on economic growth, which is based on (exogenous) volatility spillovers from abroad. Cross-section evidence from 128 countries points to a negative effect of volatility on growth.     

The role of the political cycle in the relationship between economic policy uncertainty and the long-run volatility of industry-level stock returns in the United States

In this study, we investigate how US economic policy uncertainty (EPU) drives the long-run components of volatilities in industry-level stock markets. We use a modified specification of GARCH-MIDAS and find that EPU increases the long-run volatility of the industrials and materials industries and decreases it in 4 of the 10 industries considered here: consumer staples, healthcare, information technology and materials. In addition, we add a dummy variable for the political cycle (PLC) to study whether the relationship between EPU and the volatility of industry returns is significantly different under different political regimes. The results imply that a Republican presidency dampens the effects of EPU on the long-run volatility of the consumer staples, healthcare and information technology industries. We also decompose the aggregated EPU into 11 category-specific EPUs to explore the detailed relationship between category-specific EPU and long-run volatility driven by aggregate EPU. The results for the category-specific EPU are consistent with the findings for the aggregate EPU. In particular, the weakened effect of PLC on the relationship between EPU and the long-run volatility of industry-level returns is also confirmed by MIDAS regression with beta weight scheme.     

Cultural interaction and economic development: An overview

The rising scope and intensity of interaction between culturally polarized populations in a variety of political contexts has led to the emergence of a growing body of research on the reciprocal relationship between cultural interaction and economic development. This paper offers a brief overview of this literature. It first describes the multiple channels through which cultural divisions and economic development interact. Then, motivated by these observations, it presents a theoretical framework that highlights the scope for welfare-improving policy interventions in education, immigration policy and ethnic autonomy; surveys empirical evidence on such policies; and suggests directions for further research.     

S&P 500 volatility,volatility regimes,and economic uncertainty

We assess the relationship between regime-dependent volatility in S&P 500, economic policy uncertainty, the S&P 500 bull and bear sentiment spread (bb_sp), as well as the Chicago Board Options Exchange's VIX over the period 2000–2018. Our findings from two-covariate GARCH–MIDAS (GM) methodology, regime switching Markov Chain, and quantile regressions suggest that the association of realized volatility and sentiment varies across high- and low-volatility regimes and depends on investors’ sensitivity toward incidents of market uncertainties under these regimes. The findings suggest that these indicators may not be useful in volatility forecasting, especially under high-volatility regimes.     

Forms of democracy and economic growth volatility

Using a panel of 140 countries over the 1975–2007 period, we disaggregate democracies across five institutional dimensions (government forms, electoral rules, state forms, number of veto players, and age of democracies), to study the precise forms of democracy that may explain the lower economic growth volatility (EGV) in democracies compared to dictatorships, usually emphasized by the literature. We find that, while all government forms decrease EGV to the same extent, proportional electoral rules outperform majoritarian and mixed electoral rules, suggesting a role for a more inclusive political decision-making process. In addition, EGV is significantly lower in unitary states, suggesting a role for a limited separation of power between the central government and the local authorities, while the effect of the number of veto players and the age of democracies is significant only in developed countries. Consequently, the choice between various forms of democracy may not be neutral for EGV, and, possibly, for countries' development path.     

Growth effects of leisure tourism and the level of economic development

This study examines (1) whether leisure tourism can contribute to economic growth and (2) if it does, whether its growth effects are constant across levels of economic development. Leisure tourism differs from business tourism in the causal relation with economic growth. In addition, the natural and heritage-related resources for leisure tourism are limited and not reproducible. This notion has a significant implication for the relationship between the growth effects of leisure tourism and the level of economic development. Thus, the current study focuses on leisure tourism and controls for the effects of business tourism. As an economy grows, the growth effects of leisure tourism are expected to diminish due to a lack of continued productivity improvement in the tourism industry. The empirical findings in this research reveal that leisure tourism contributes to economic growth at an early stage of economic development, but its contribution becomes weaker as the economy develops.     

On the interaction between public and private capital in economic growth

This paper introduces two forms of interaction between private and public capital in an endogenous growth model in which productive government expenditure takes the form of a stock-variable and public capital is used in part as an input in the production of final output and in part to increase its own supply. While the first form of interaction involves the stocks of the two capital-goods and takes place within the final output sector through the specification of the aggregate production function (Cobb?CDouglas vs. CES), the second one concerns the rates of investment in the two kinds of capital. The share of productive public expenditure devoted to output production can be either exogenous or endogenous. Our results suggest that when this share is exogenous, along the balanced growth path the optimal growth rate of the economy is a positive function of the degree of complementarity between the two forms of investment. When the share of productive public expenditure devoted to output production is endogenous, the public capital share in GDP becomes, along with the model??s preference parameters, an important determinant of the economy??s long run growth. We also find that the optimal growth rate is an increasing function of the elasticity of substitution between public and private capital inputs in goods production, and is independent of the complementarity/substitutability between the two forms of investment.     

Mandatory spending,political polarization,and macroeconomic volatility

This paper studies the impact of political polarization on macroeconomic volatility in a political economy model of optimal fiscal policy. I introduce the distinction between mandatory and discretionary public spending in a model where consumers disagree on the size of the public sector. In the presence of political turnover and political polarization, public policies that affect individual decision-making lead to macroeconomic volatility. I show that the legislative requirements behind the changes in mandatory public spending can reduce macroeconomic volatility caused by political polarization and political turnover. The numerical simulations of the model suggest that in the presence of a binding constraint on the changes in mandatory spending, an increase in the political polarization is associated with an increase in the share of mandatory spending and a decrease in the macroeconomic volatility, consistent with the U.S. data.     

Romes without empires: Urban concentration,political competition,and economic development

Many developing economies are characterized by the dominance of a super metropolis. Taking historical Rome as the archetype of a city that centralizes political power to extract resources from the rest of the country, we present evidence that urban concentration, as proxied by the limited number of cities with national soccer league titles in a country, negatively affects long-run economic development. Utilizing cross-country data from 103 countries observed over half a century (1960–2009), we show that there is a strong and robust negative relationship between concentration of economic wealth and political power across urban nodes and long-run economic outcomes, including log per capita income and average years of schooling. The explanation that best seems to fit the evidence runs from centralization of economic power to lack of inter-elite political competition across space to inferior economic outcomes in the long-run. To establish causality we use identification through heteroskedasticity, which does not rely on standard exclusion restrictions.     

Combining biodiversity modeling with political and economic development scenarios for 25 EU countries

In the EURURALIS project, a chain of models was used to predict the changes in sustainable development indicators for European human well-being, ecology and economy issues, for four alternative scenarios of the future socio-economic development. This paper describes the biodiversity analysis of the project. Models based on general relationships between environmental factors and biodiversity loss were combined with socio-economic, land-use and environmental models to derive data that were integrated into an interactive tool for policy makers. The biodiversity analysis takes into account the effects of land-use change, climate change, fragmentation by major roads, area of unfragmented patches, nitrogen deposition, forestry and disturbance. Results show that biodiversity is projected to decrease between now and 2030 in most countries for all scenarios, indicating that it is unlikely that the EU will be able to fulfill its commitment to stop biodiversity loss by 2010. This is mainly due to urbanization and increase in stress factors, and outweighs the area increase of nature arising from land abandonment. Merits, limitations and uncertainties of this approach to biodiversity assessment are discussed.     

Estimating the long-run relationship between income inequality and economic development

There are several theories describing the effect of income inequality on economic growth. These theories usually predict that there exists some optimal, steady-state growth path between inequality and development. This study uses a new measure of income distribution and panel data cointegration methods to test for the existence of such a steady-state equilibrium relation. It is shown that there is a long-run equilibrium relationship between the variables, and that this relationship is negative in developed economies.     

The relationship between factor shares and economic development

The stability of factor shares has long been considered one of the “stylized facts” of macroeconomics. Most factor share studies, however, acknowledge only two factors of production (total capital and total labor), which yields misleading results. I distinguish between reproducible and non-reproducible factors of production. I disentangle physical capital’s share from natural capital’s share and human capital’s share from unskilled labor’s share. Results reveal that non-reproducible factor shares decrease with the stage of economic development, and reproducible factor shares increase with the stage of economic development. This evidence suggests that studies relying on the macroeconomic paradigm of constant factor shares should be revisited. The evidence also supports endogenous growth models that allow technical progress to manifest itself via changes in factor shares.     

Human rights and political and economic instability

The purpose of this paper is to use cross country regression analysis on a large set of countries from around the world for the year 2007 to test the hypothesis that greater instability, political or economic leads to reduced levels of human rights. The results of the paper＇s econometric analysis tend to support the hypothesis that increased levels of either political instability or economic instability are detrimental to human rights within countries.     

Education for the masses? The interaction between wealth,educational and political inequalities

This paper presents a simple model of distribution dynamics, in which the distributions of wealth, education and political power are circularly endogenous. Different levels of education translate into different income and wealth levels. Political power may (or may not) vary with wealth, and in turn affects decisions on the level of public expenditure on education. Since the market for education credit is imperfect, some people might need to rely on public schooling, the quality of which depends on those expenditure levels. As a result, educational opportunities differ along the wealth distribution. The dynamic system displays multiple equilibria, some of which are characterized by a vicious circle of interaction between educational, wealth and political inequalities. These particular equilibria, which are more unequal, are also shown to be inefficient in terms of aggregate output levels. Switching equilibria may be achieved through redistribution of political power.

Political democratization, economic liberalization, and growth volatility

This study empirically investigates the effects of political and economic liberalization on growth volatility using a difference-in-difference method for a sample of 158 countries over the 1970-2005 period. The results show that, when examined separately, economic liberalization leads to a significant reduction in volatility while democratization is not followed by a decrease in growth volatility. For countries that undertake only one liberalization, opening up the economy to international trade reduces volatility in growth; becoming a democracy, on the other hand, seems to increase macroeconomic instability. For countries that implement both political and economic liberalizations, no statistically significant effect on volatility is detected. These results serve to provide additional support for the policy recommendation that developing countries should liberalize their economy first and then consider political liberalization.     

Government size, composition, volatility and economic growth

This paper analyses the effects in terms of size and volatility of government revenue and spending on growth in OECD and EU countries. The results of the paper suggest that both variables are detrimental to growth. In particular, looking more closely at the effect of each component of government revenue and spending, the results point out that i) indirect taxes (size and volatility); ii) social contributions (size and volatility); iii) government consumption (size and volatility); iv) subsidies (size); and v) government investment (volatility) have a sizeable, negative and statistically significant effect on growth.
