The KOF Globalisation Index – revisited

Abstract: We introduce the revised version of the KOF Globalisation Index, a composite index measuring globalization for every country in the world along the economic, social and political dimension. The original index was introduced by Dreher (Applied Economics, 38(10):1091–1110, 2006) and updated in Dreher et al. (2008). This second revision of the index distinguishes between de facto and de jure measures along the different dimensions of globalization. We also disentangle trade and financial globalization within the economic dimension of globalization and use time-varying weighting of the variables. The new index is based on 43 instead of 23 variables in the previous version. Following Dreher (Applied Economics, 38(10):1091–1110, 2006), we use the new index to examine the effect of globalization on economic growth. The results suggest that de facto and de jure globalization influence economic growth differently. Future research should use the new KOF Globalisation Index to re-examine other important consequences of globalization and why globalization was proceeding rapidly in some countries, such as South Korea, but less so in others.

The Evidence on Globalisation

Abstract: Globalisation is blamed for many socioeconomic shortcomings. I discuss the consequences of globalisation by surveying the empirical globalisation literature. My focus is on the KOF indices of globalisation that have been used in more than 100 studies. Early studies using the KOF index reported correlations between globalisation and several outcome variables. Studies published more recently identify causal effects. The evidence shows that globalisation has spurred economic growth, promoted gender equality and improved human rights. Moreover, globalisation did not erode welfare state activities, did not have any significant effect on labour market interaction and hardly influenced market deregulation. It increased, however, within-country income inequality. The consequences of globalisation thus turn out to be overall much more favourable than often conjectured in the public discourse.

Did globalization restrict partisan politics? An empirical evaluation of social expenditures in a panel of OECD countries

Abstract: This paper evaluates empirically how, in the course of globalization, partisan politics affected social expenditures in a panel of OECD countries. I introduce an updated indicator of government ideology and investigate its interaction with the KOF index of globalization. Two basic results emerge: First, at times when globalization proceeded at an average pace, partisan politics had no effect on social expenditures, but leftist governments increased social expenditures when globalization was proceeding rapidly. Second, policies differed in the 1980s and 1990s: Leftist governments pursued expansionary policies in the 1980s. Yet partisan politics disappeared in the 1990s, but not because of globalization.

Islam and Democracy

Abstract: Using the POLITY IV and Freedom House indices, Rowley and Smith (2009) found that countries with Muslim majorities enjoy less freedom and are less democratic than countries in which Muslims are a minority. Because the POLITY IV and Freedom House indices have been criticized on several grounds, I reinvestigate Rowley and Smith’s finding using the new Democracy-Dictatorship data from Cheibub et al. (2010). The empirical results confirm that countries with Muslim majorities are indeed less likely to be democratic.

Does government ideology influence deregulation of product markets? Empirical evidence from OECD countries

Abstract: This paper examines how government ideology has influenced deregulation of product markets in OECD countries. I analyze a dataset of non-manufacturing regulation indicators covering energy, transport and communication industries in 21 OECD countries over the 1980–2003 period and employ two different indices of government ideology. The results suggest that government ideology has had a strong influence on the deregulation process: market-oriented governments promoted the deregulation of the energy, transport and communication industries. This finding identifies remarkable differences between leftist and rightwing governments concerning the role of government in the economy and basic elements of political order.

Economic growth and income inequality

Abstract: We investigate whether income inequality affects subsequent growth in a cross-country sample for 1965-90, using the models of Barro (1997), Bleaney and Nishiyama (2002) and Sachs and Warner (1997), with negative results. We then investigate the evolution of income inequality over the same period and its correlation with growth. The dominating feature is inequality convergence across countries. This convergence has been significantly faster amongst developed countries. Growth does not appear to influence the evolution of inequality over time. Outline
