Conflict technology in cooperation: The group size paradox revisited

This paper studies the implications of punishment‐induced conflict in a public goods game. It shows, under plausible assumptions, how larger group size sometimes enhances punishing behavior in social dilemmas and hence supports higher levels of cooperation. Unlike existing approaches that focus on uncoordinated punishment, I consider punishment as a coordinated activity that may be resisted by those being punished and study the implications of punishment‐induced conflict situations. Developing a conflict model of punishment and combining it with a standard public good game, I show that coordinated punishment can yield the concentration effect of punishment, leading to a larger group advantage; that is, the larger the group, the easier it becomes to organize cooperation. The key idea is that when punishers coordinate their punishment, punishers as a coalition successfully divide defectors and punish each defector one by one. Surprisingly, even when coordination among punishers decays as group size increases, as long as the rate of decaying remains relatively slow the larger group advantage still obtains.     

A Strategic Implementation of the Shapley Value for the Nested Cost‐Sharing Problem

When agents have different needs for a public facility but serving a given agent allows serving all agents with smaller needs than his without any extra cost, how should the agents divide the cost of the facility among themselves? We provide a strategic implementation of the Shapley value for this class of cost‐sharing problems. We introduce a three‐stage extensive form game that respects individual rationality and show that there is one and only one subgame‐perfect equilibrium outcome of the game. Moreover, it is the allocation assigned by the Shapley value.     

Discounting and welfare evaluation of policies

We start with the premise that if policy discounting is to have any welfare relevance, one has to accept it being a derivative of a social welfare function (SWF). We show that if that derivative is to have a net present value (NPV) form, then the baseline allocation must be stationary. In addition, we show that at a stationary baseline in an overlapping generations growth economy, the intergenerationally fair discount rate equals the growth rate of per‐capita consumption, which is, roughly, 2% for the United States. This differs from the interest rate, even in the golden rule equilibrium, unless population growth is null. The last result is based on the main theorem in Mertens and Rubinchik (2012) and is demonstrated for a policy space that might naturally arise in applications.     

Do people gamble more in good times? Evidence from 27 European countries

We provide evidence of a positive relationship between the intensity of gambling and economic growth in 27 European countries for 2005–2013. Our proxy for gambling is represented by government revenues from taxes on lotteries, betting and gambling. This variable is linked to GDP growth in a panel regression framework and pooled OLS. However, when we split our sample to account for the heterogeneity among European countries, we found that the positive ‘gambling – GDP growth’ relationship is driven extensively by the Central and Eastern European countries. It appears that people in these countries tend to gamble more when the economy is expanding.     

Monetary policy regime change and regional inflation dynamics: looking through the lens of sector‐level data for Korea

This paper explores the impact of the adoption of inflation targeting (IT) on the dynamics of city‐level inflation in Korea using both aggregate and sector‐level data. When looking at aggregate regional inflation, we find that the mean, volatility and persistence fell in all cities in the wake of the monetary policy regime change, consistent with other evidence in the literature. Delving more deeply into the disaggregate data reveals additional insights however. For most of the changes we observe in the dynamics of regional inflation, we find that the aggregate effects are being driven primarily by sectors that fall into the ‘Services’ category. We posit that the impact of better anchored inflationary expectations is primarily on the less‐traded services sectors of the economy, where the domestic monetary policy framework has a relatively larger influence. When it comes to the increased co‐movement observed across regions under an IT regime, however, it is the ‘Commodities’ sectors rather than ‘Services’ that are responsible, probably because services inflation becomes relatively more influenced by local factors once it has stabilized within the target range. Therefore, adoption of IT may not necessarily increase all measures of regional synchronization even when the goal of better‐anchored inflationary expectations is achieved.     

Is Private Saving in Latin America and the Caribbean Different?

Private saving and economic growth are intimately linked, and low saving rates in Latin America and the Caribbean (LAC) have often been held responsible for disappointing growth in the region. Thus, identifying factors that spur saving is critical. This paper surveys previous empirical studies on LAC, highlighting contradictions, omissions and in some cases inconclusiveness of findings. Relying on a large dataset and a nested econometric framework, it analyzes private saving patterns and explores the role of its determinants in LAC, across LAC sub‐regions and compared with other regions. While the results highlight great heterogeneity in private saving rates within LAC and compared with the rest of the world, saving determinants are broadly the same notwithstanding some differences in sensitivity and contributions' sizes, and include its lag, income, demographics and public saving.     

Asymmetric Effects of Exchange Rate Changes and the J‐curve: New Evidence from 61 Malaysia–Thailand Industries

Research on the impact of currency depreciation on the trade balance is now moving in a new direction by incorporating nonlinear dynamic adjustment of the exchange rate and by using a nonlinear approach to error‐correction modeling and cointegration. Using these advances, researchers find not only more evidence of the J‐curve effect, but also new evidence of asymmetric effects of exchange rate changes on the trade balance. We contribute to this line of research by using monthly trade flow data from 61 two‐digit industries that trade between Malaysia and Thailand, and show that not only does currency depreciation have favorable effects on the trade balance of more industries, but the long‐run effects are asymmetric in 26 out of 61 cases. In line with current literature, our nonlinear model performs much better than the linear model when industry level data are used.     

When a Door Closes,a Window Opens? Long‐Term Labor Market Effects of Involuntary Separations

This study estimates the earning losses of workers experiencing an involuntary job separation. We employ, for the first time in the earning losses literature, a Poisson pseudo‐maximum‐likelihood estimator with fixed effects that has several advantages with respect to conventional fixed effects models. The Poisson estimator allows considering the full set of involuntary separations, including those with zero labor market earnings because of unemployment. By including individuals with zero earnings and by using our new method, the loss in the year of separation becomes larger than in previous studies. The loss starts with roughly 30% and, although it quickly shrinks, it remains at around 15% in the following years. In addition, we find that compared to other reasons for separation, the earning loss pattern is unique for involuntary separations, because no other type of separation implies such permanent scarring. This latter finding makes us confident that the self‐reported involuntariness of a separation is a reliable source of information.     

EFFECTS OF A CHILD'S DISABILITY ON AFFECTED FEMALE'S LABOUR SUPPLY IN AUSTRALIA

Australia has experienced a growing rate of child disability, with the rate of 3.7 per cent in 1998 increasing to 4.3 per cent in 2003 for children aged under four years and from 9.5 per cent to 10 per cent for children aged five to 14 years in the same period. However, surprisingly no study has examined the economic effects of child disability in the Australian context. This paper attempts to quantify the link between a child's disability and the work behaviour of the female in the affected family. Our findings provide empirical justifications for the current policy linking the severity level of child disability to the assessment of eligibility for Carer Payment (Child). We also found that child disability has different impacts on the labour market activities of married women and non‐married women. It appears that child disability imposes a greater hardship on non‐married women than on married women in terms of work choice decision. Once non‐married women manage to enter the labour force, they may have to stay on to work as usual even if they have a disabled child, because they may not have other family members to turn to for help as married women do.
