Coups,revolutions and efficient policies in autocracies

The purpose of this paper is to explore the interaction of two mechanisms that might constrain the power of dictators: the threat of a coup by the selectorate and a revolution by citizens. Our results help explain a stylized fact, namely that autocracies are far more likely to be either the best or the worst performers in terms of growth and public goods policies. To this end, we focus on accountability within dictatorships using a model where both the selectorate and the citizens are the principals and the autocrat is the agent. Our results highlight that both excessively strong and excessively weak dictators lead to poor economic performances, and that a balanced distribution of de facto political power is required to incentivize the dictator to choose efficient economic policies.     

Citizens, Autocrats, and Plotters: A Model and New Evidence on Coups D'État

We present a model of coups in autocracies. Assuming that policy choices cannot be observed but are correlated with the short-run performance of the economy we find that: (a) the threat of a coup disciplines autocrats; (b) coups are more likely in recessions; (c) increasing per capita income has an ambiguous effect on the probability of a coup. The implications of the model are consistent with the evidence. On average, one recession in the previous year increases the probability of a coup attempt by 47 percent. By contrast, the effect of the level of per capita income is weak.     

Optimal fiscal policy in a world liquidity trap

We construct a model of the international transmission of ‘liquidity trap’ shocks, and examine the case for international coordination of fiscal policy to respond to the liquidity trap. Integrated financial markets tend to propagate liquidity traps. In a global environment, fiscal policy may be effective in raising GDP when the economy is stuck in a liquidity trap, but it does so in a ‘beggar thy neighbor’ fashion; when one economy is in a liquidity trap, the cross country spillover effect of fiscal policy is negative. We examine the welfare optimizing policy response to a liquidity trap when countries coordinate on fiscal policy. Fiscal policy may be an effective tool in responding to a liquidity trap, although it is never optimal to use fiscal expansion sufficiently to fully eliminate a downturn. Moreover, there is little case for coordinated global fiscal expansion. For the most part, the country worst hit by a liquidity trap shock should use its own policies to respond, without much help from foreign policies.     

A Game-Theoretic Model Of The CouP D'État

I explore the comparative vulnerability of regimes to a coup d'état using a game-theoretic model. Analysis centers on leaders of groups capable of intervening at the time of a coup. I prove the existence of an equilibrium in which a coup is attempted without restrictions on current government policy, the breadth of participation in politics, or the relative size of the conspiracy. Comparative statics results concerning the willingness of plotters to stage a coup and other leaders to join a coup once under way are established. Differences in comparative regime vulnerability stem from differences in the amount of organization required to attempt a coup.     

COOPERATION, COOPTATION, AND REBELLION UNDER DICTATORSHIPS

Dictatorships are not all the same: some are purely autocratic but many exhibit a full panoply of seemingly democratic institutions. To explain these differences, we develop a model in which dictators may need cooperation to generate rents and may face a threat of rebellion. Dictators have two instruments: they can make policy concessions or share rents. We conclude that when they need more cooperation dictators make more extensive policy concessions and share fewer rents. In turn, when the threat of rebellion is greater, they make larger concessions but also distribute more spoils. Assuming that policy concessions require an institutional setting of legislatures and parties, we test this prediction statistically for all dictatorships that existed between 1946 and 1996.     

The effect of managerial ability on dividend policy: how do talented managers view dividend payouts?

We contribute to the literature on dividend policy by relaxing Miller and Modigliani’s (1961) perfect capital market assumptions and incorporating a factor that has not been investigated before, that is, variation in managerial ability. Based on more than 24 000 observations across over 20 years (1989–2011), our results show that firms with more talented executives are more likely to pay dividends and, among firms that pay dividends, pay significantly larger dividends. A rise in managerial ability by one SD raises the propensity to pay dividends by 27% and, for firms that pay dividends, increases dividend payouts by 29%. Our results are consistent with the notion that talented managers, confident in their ability to keep the firm profitable, are more willing to pay larger dividends because they are less concerned about having to reduce dividends in the future. Further analysis shows that our results are not likely vulnerable to endogeneity.     

A Public Choice Approach to Strategic and Nonstrategic Environmental Policy

In this paper we take a public choice perspective on strategic environmental policy and international environmental agreements. We examine cooperative and noncooperative environmental policies under governments that are either welfare maximizers (“good dictators”) or tax revenue maximizers (“Leviathans”). We show that Leviathans can perform better in terms of welfare and that good dictators can set higher taxes. We then analyze international environmental agreements and show that the breakdown of environmental cooperation can indeed lead to a welfare gain for all signatory countries. Considering a delegation game between governments, we find that a Pareto‐superior Leviathan outcome can be the unique Nash equilibrium.     

Controling tax evasion under direct and indirect taxation: Some notes

The purpose of the paper is to use a simple model of the firm having monopoly power in the goods market as the framework to study the relative effectiveness of unit, ad valorem and profit taxes under two alternative criteria when the taxes are changeds so as to keep either the expected utility of the monopoly firm or the expected tax revenues for government constant. Under the former policy the profit tax turns out to be best and the unit tax worst in all respects; for instance, the profit tax will give rise to higher production, lower prices, lower tax evasion and higher tax revenues for government than other taxes. The dominance of the profit tax and the inferiority of the unit tax still holds under the policy of keeping the expected tax revenues constant in terms of production, prices and the expected utility of the monopoly firm. But strikingly, in terms of effectiveness of tax evasion control the ranking of taxes is now exactly the reverse from the one obtained under the expected utility criterium; now the unit tax is best and the profit tax worst.     

Asset booms and fat tails in East Asia: Symmetric or asymmetric risks?

Do housing and equity booms significantly raise the probability at the margin of the realization of extreme outcomes in output and prices, and are the worst outcomes just as likely to occur as the good ones? This study addresses these questions for a group of eight East Asian countries. The risk of extreme outcomes occurring is measured by the probability of being in the tails of a distribution. The distributions of real output-and price level-gaps exhibit fat tails, in which the probability and size of the worst possible outcomes are higher than if the distribution were normal. Expected real output- and price level-losses from asset booms would therefore be larger than suggested by the normal distribution if asset price booms significantly raise the risk of extreme outcomes occurring. The main findings are that (i) asset price booms in housing and equity markets, but especially in housing, significantly raise the probability at the margin that real output- and price level-gaps will be in the tails of worst outcomes of their respective distributions and (ii) the risks arising from asset booms are not symmetric-only particularly bad outcomes are more likely. The implication for monetary policy is that an approach that is ex-ante more compatible with risk management may be appropriate.     

Fiscal Decentralization and Political Budget Cycles

We analyze a problem à la Rogoff where incumbents can distort fiscal policy to signal their competency, but where fiscal policy can be centralized or decentralized. Our main focus is on how the equilibrium probability that fiscal policy is distorted in any region (the political budget cycle, PBC) differs across fiscal regimes. With centralization, there are generally two effects that change the probability of a PBC. One is the possibility of selective distortion: the incumbent can be reelected with the support of just a majority of regions. The other is a cost diversification effect, which is present unless costs are perfectly correlated across regions. Both these effects work in the same direction, with the general result that the PBC probability is lower under centralization when decentralization also involves PBC. Welfare analysis shows that voters tend to be better off when the PBC probability is lower, so voters prefer centralization when decentralization involves PBC. Our results are robust to a number of changes in the specification of the model.     

The hump-shaped behavior of inflation and a dynamic externality

We propose a general equilibrium model that explains the empirical evidence of the hump-shaped response of inflation to a monetary policy shock. The model replaces backward-looking indexation à la Christiano et al. [2005. Nominal rigidities and the dynamic effect of a shock to monetary policy. Journal of Political Economy 113(1), 1-45] with a dynamic externality into the production function of firms. The model, armed with sticky wages and variable capital utilization, has two offsetting effects on real marginal cost over the business cycle. First, increasing factor prices raise real marginal cost in response to an expansionary monetary policy shock in the intermediate run. Second, a dynamic externality reduces real marginal cost in the short run because it raises productivity in response to an increase in output following the shock. Overall, the resulting short-run decrease and intermediate-run increase in marginal cost replicate the hump-shaped behavior of inflation under purely forward-looking price and wage Phillips curves.     

Inflation Aversion and Exit Probabilities in the Monetary Unions

The paper considers a monetary union composed of two representative countries characterized by different inflation aversions. The model derives Nash equilibria after a country-specific shock in which the countries have a costly option to abandon the common currency. The main results are that the higher the inflation aversion of the country affected by the shock, the lower its exit probability. The higher the inflation aversion in both countries, the lower the probability that the country not directly hit also abandons the monetary union (contagion).     

Enforcement and Information Strategies

In this paper we show that, if the relation between the actual monitoring probability and the extent of compliance in the regulated population is concave to the actual probability axis, providing perfect information raises compliance rates, relative to what might be called the “keep-them-ignorant” option. We also illustrate that a quite simple method is available for checking whether, in a particular setting with a particular class of regulated parties, the full information or the keep-them-ignorant policy ought to be pursued.     

The Probability of Leaving Unemployment: The Influence of Duration,Destination and Demographics*

This paper examines the influences of a number of demographic characteristics and the duration of unemployment on the probability of leaving unemployment. This probability is found to decrease as the duration of unemployment increases, with married females having the highest probability of exit. Various measures of average completed duration suggest that the longest spells of unemployment are incurred by older males. These appear to be longest for males withdrawing from the labour market. The relationship between the duration of unemployment and the probability of exit is important for labour market policy. Some relevant considerations are also explored in the paper.     

Evaluating monetary policy with financial stability objective: rules vs. discretion

This article explores whether adding the goal of financial stability to the more traditional goals of output and price stability could improve optimality of monetary policy. A Dynamic Stochastic General Equilibrium model that endogenously incorporates financial frictions is used to derive optimality conditions across rule-based and discretionary monetary policy environments. The results indicate that it is optimal for the Central Bank to keep output below the potential level in the short term so as to dampen the inflationary effects arising from supply and financial shocks. When the economy is exposed to a financial shock, both leverage and credit spread rise significantly, thereby tipping the economy into a financial crisis and raising the probability of macroeconomic risk.     

Dissertation abstract: Experiments on fairness and reputation

The three dissertation essays investigate different aspects of reputation in games where fairness is an important consideration. The first essay studies the effects of reputation on indirect reciprocity in different dictator games. The first experiment places dictators in two environments where they can either give money to the paired player or take money away from them: in one treatment the paired player is a stranger and in the other treatment the dictator has information on the paired player’s reputation. Contrary to anecdotal evidence, the statistical tests show that the dictators’ behavior towards a stranger is not statistically significantly different from their behavior towards an individual with an established reputation. The findings arise because a high proportion of dictators acted purely in their own self interest in both treatments. The data also provides evidence that dictators are more generous when they know that their choices (but not their identities) will be revealed in the future. In the second experiment the dictators’ choices were restricted to only generous actions. In such environment the dictators sent more money on average to recipients with a reputation for being generous than to recipients without a reputation. The second essay explores the ways in which information about others’ actions affects one’s own behavior in a dictator game. The experimental design discriminates behaviorally between three possible effects of recipient’s within-game reputation on the dictator’s decision: reputation causing indirect reciprocity, social influence, and identification. The separation of motives helps to identify the mechanisms of social transmission of impulses towards selfish or generous behavior. The data analysis reveals that the reputation effects have a stronger impact on dictators’ actions than social influence and identification. In the third essay¹ we examine the reputation effects in a labor market setting by analyzing the influence of negative technological shocks on long run relationships between firms and workers. The positive correlation between wage and effort in static conditions has been demonstrated in many experimental studies and has been one of the prominent explanations for the existence of wage rigidity. We subject these findings to further tests in a non-stationary environment that better corresponds to outside-the-lab market conditions. We observe the positive correlation of wages and effort but do not find support for downward wage rigidity in our data. Once the shocks occur, firms lower the wages and relationships often break down. The workers who accept a lower wage respond with exerting a lower effort.

Modelling labour market dynamics with on-the-job search

A flow model of the Dutch labour market is used to calculate the effects of policy options which aim to enhance employment, especially at the lower end of the labour market. The model distinguishes between good and bad jobs, allows for endogenous wage formation and job creation, and describes the flows between these jobs so that job-to-job mobility and the vacancy chain is made endogenous. In the matching process employed job seekers with bad jobs compete with short-term and long-term unemployed for the filling of vacancies for good jobs. In each period part of the good and bad jobs are destroyed which results in inflow into unemployment. The model explicitly describes the flow of unemployed through the various duration classes of unemployment and it allows for negative duration dependence so that the escape probability from unemployment for long-term unemployed is smaller than for short-term unemployed. The model is used to simulate the effects of external shocks, such as structural productivity shocks. An impulse response analysis using the model is also conducted considering labour market policies which aims especially to enhance employment at the lower end of the labour market. In particular, the effects are analysed of measures subsidising the opening of bad jobs (jobs at the lower end of the labour market) and a rise in the productivity of a bad job as compared to a good job which can be achieved by changes in the tax system.     

Are dictators averse to inequality?

We present the results of an experiment designed to identify more clearly the motivation underlying dictators’ behavior. In the typical dictator game, recipients are given no endowment. We give an endowment to the recipient as well as the dictator. This new dimension allows us to test directly for inequality aversion. Our results confirm that the inequality between dictator's and recipient's endowment is a key determinant of the dictator's giving. As we increase the recipient's endowment from 0 to an amount equal to the dictator's endowment, the mean amount passed drops from 30 percent to less than 12 percent of the dictator's endowment, and the proportion of dictators who pass positive amounts falls from 75 percent to 26 percent. Thus the majority of dictators exhibit behavior consistent with inequality averse preferences. On the other hand, only 24 percent of dictators split payoffs equally suggesting that maximin preferences are less important drivers of dictators’ giving.
