THE ENDOGENOUS AND NON‐LINEAR RELATIONSHIP BETWEEN TERRORISM AND ECONOMIC PERFORMANCE: TURKISH EVIDENCE

This paper investigates the macroeconomic effects of terror by using a novel data set from Turkey for the period of 1987:1 to 2004:4. This research contributes to the literature by controlling for the possible non‐linear and endogenous relationship between political conflict and economic activity. Empirical evidence from both linear and non‐linear models confirms that terrorism has a large significant negative impact on economic activity. Finally, the results from the non‐linear model show that the impact of terrorism on the aggregate economy is more severe during expansionary periods, and that the impact of economic activity on terrorism is significant only in recessionary periods.

Revisiting the Determinants of Entrepreneurship: A Bayesian Approach

Entrepreneurship has long been seen as an important instrument in stimulating and generating economic growth. The amount of research trying to identify key factors that drive entrepreneurship is considerable; yet, little consensus has been achieved. We argue that this lack of consensus could be on account of model uncertainty as empirical studies often tend to be selective on what variables are included in the final model. Drawing on recent literature, we demonstrate the benefits of Bayesian model averaging (BMA) in reducing the impact of model uncertainty on empirical research in entrepreneurship. Additionally, BMA provides measures of variable importance and can be seen as a complementary approach to dominance/relative importance analysis. We show that when model uncertainty is corrected for, gross domestic product per capita, unemployment, the marginal tax rate, and the volatility of inflation are the only macro variables significantly and universally associated with aggregate entrepreneurship. Furthermore, the emphasis on inflation and taxation suggests that governments have the power to influence the quantity and distribution of entrepreneurial activity by setting incentives that are not entrepreneurship specific but overlap significantly with general and fundamental principles of economic stability.

Fiscal Policy, Private Investment and Economic Growth: Evidence from G-7 Countries

Measuring the effects of fiscal policy on economic growth is difficult, because fiscal policy variables are influenced by changes in income. This paper uses an unbalanced panel data set for G-7 countries for the period 1965-2000 that includes annual estimates of cyclically adjusted government expenditures, capital outlays, income tax revenues, indirect tax revenues, corporate tax revenues and social security tax revenues, based on definitions developed by OECD revenue statistics. The percentage share of these estimates in GDP is used to investigate the effects of fiscal policy on economic growth, and results are compared with regression results that use 5-year averages of cyclically unadjusted variables. The empirical results from both sets of regressions suggest that only taxes on household income and government expenditures have negative effects on per capita income growth. We consolidate our findings by showing that both government expenditures and income taxes have distortionary effects on private investment.

You are One of Us Now! How Do Share Prices of Rivals React to Privatization?

By using a unique data set from the Turkish cement industry, we analyze the impact of privatization on the market value of rival firms. Privatization increases efficiency, which is bad news for rivals. But if an incumbent buys a state owned firm, this leads to a higher market concentration which is good news for rivals. We show that privatization leads to overall positive abnormal returns for rivals because the concentration effect outweighs the efficiency effect. Consistent with our theory, this effect is reinforced when the initial market concentration is high.

Is Roger Federer more loss averse than Serena Williams

ABSTRACT Using data from the high-stakes 2013 Dubai professional tennis tournament, we find that, compared with a tied score, (i) male players have a higher serve speed and thus exhibit more effort when behind in score, and their serve speeds get less sensitive to losses or gains when score difference gets too large, and (ii) female players do not change their serve speed when behind, while serving slower when ahead. Thus, male players comply more with Prospect Theory exhibiting more loss aversion and reflection effect. Our results are robust to controlling for player fixed effects and characteristics with player random effects.

Critical thresholds for budget consolidations: a semi-parametric approach

While a lot is known regarding the determinants of successful fiscal consolidations, previous studies do not allow for the possibility of nonlinearities in factors impacting budget consolidations. By using a semi-parametric modelling approach employing penalized spline regression on a data-set for 28 OECD countries for the period 1978–2007, we demonstrate the existence of critical thresholds not only for the initial debt level but also for the accompanying monetary policy. The latter result shows when monetary policy matters most and suggests, counter to previous studies, that too lax a monetary policy decreases the success probability of a fiscal adjustment episode.

Is it Inflation or Inflation Variability? A Note on the Stock Return-Inflation Puzzle

This paper investigates the effects of inflation and inflation variability on the economic and stock market activity within a VAR framework by using U.S data for the 1988:01-2002:12 period. Our results show that the detrimental effects of inflation come from the inflation variability, not the level of inflation itself.

Revisiting the growth effects of fiscal policy: A Bayesian model averaging approach

Motivated by the mixed evidence in previous literature, we reexamine the effects of various types of government spending and taxes, as well as overall budget surplus/deficit, on economic growth. To address the model uncertainty issue that may have plagued earlier studies we employ a Bayesian Model Averaging (BMA) approach. We use a panel data set for OECD countries for the 1990-2013 period, control for country and time specific effects, and allow for a wide range of other potential growth determinants. The results suggest a robust link between only some fiscal variables and economic growth. On the spending side, productive public spending has a robust positive effect on growth. On the revenue side, we document a robust negative effect for the top corporate tax rate, but, maybe surprisingly, not for any income tax variable. Finally, our results suggest that a budget surplus has a robust positive effect on economic performance. We also analyze the timing of effects and conclude that most effects occur with a lag of two years.

The political consequences of ethnic tension: Theory and evidence

By counting the number of articles published in major US newspapers containing carefully selected keywords, we construct a time varying measure of ethnic tension. Then, we empirically test the predictions of a theoretical model by using the aforementioned measure, and investigate how ethnic tension affects presidential approval ratings by different ethnic groups. Our results show that while ethnic tension decreases the approval by white voters, the opposite is true for the approval by African American voters. Further scrutiny reveals that this may be explained by the fact that government transfers to African Americans increase as a result of higher ethnic tension.

Trans‐Tasman Transmission of Government Spending Shocks

This paper investigates the international transmission of fiscal shocks between two closely‐linked, open economies. We estimate impulse response functions using a semi‐structural vector auto regressive (VAR) model and quarterly data from Australia and New Zealand for the period 1973:3–2008:4. We compare our empirical results with impulse response functions from a calibrated two‐country international real business cycle model with habit formation and adjustment costs to investment. We show that a positive shock to Australian government consumption leads to an increase in Australian output initially and then to a decline in the medium term, while the New Zealand output is negatively affected both in the short and medium term. This result is in line with the recent literature that reports beggar‐thy‐neighbour effect of positive government spending shocks.
