Big and Tall: Is there a Height Premium or Obesity Penalty in the Labor Market?
Previous studies have shown that both height and BMI are associated with wages. However, by focusing on interpreting the partial effects of either height or BMI on wages while holding all else constant, some gaps in our understanding of the complex relationship between body size and wages remain. Utilizing a semi-parametric spline approach, we first establish that a flexible analysis of height and weight provides a useful and meaningful proxy for beauty. A similar flexible analysis of height, weight and wages reveals that some combinations of anthropometric measurements attract higher wage premiums than others and that the optimal combination varies over the life cycle. A main contribution of the paper is in suggesting a novel and practical way of examining the returns to looks in the labor market based on objective anthropometric measurements.

Designing Fair Tiebreak Mechanisms: The Case of FIFA Penalty Shootouts
In the current FIFA penalty shootout mechanism, a coin toss decides which team will kick first. Empirical evidence suggests that the team taking the first kick has a higher probability to win a shootout. We design sequentially fair shootout mechanisms such that in all symmetric Markov-perfect equilibria each of the skill-balanced teams has exactly 50% chance to win whenever the score is tied at any round. Consistent with empirical evidence, we show that the current mechanism is not sequentially fair and characterize all sequentially fair mechanisms. Taking additional desirable properties into consideration, we propose and uniquely characterize a practical mechanism.

The Bargaining Correspondence: When Edgeworth Meets Nash
A new, more fundamental approach is proposed to the classical bargaining problem. The give-and-take feature in the negotiation process is explicitly modelled under the new framework. A compromise set consists of all allocations a bargainer is willing to accept as agreement. We focus on the relationship between the rationality principles (arguments) adopted by bargainers in making mutual concessions and the formation of compromise sets. The bargaining correspondence is then defined as the intersection of bargainers compromise sets. We study the non-emptyness, symmetry, efficiency and single-valuedness of the bargaining correspondence, and establish its connection to the Nash solution. Our framework provides the first rational foundation to Nashs axiomatic approach, and hence bridges the Edgeworth-Nash gap.

Securing Unlimited Water Supply in Adelaide over the Next Century Balancing Desalinated and Murray-Darling Basin Water
This paper assesses the two major water supply options for a growing but relatively dry metropolitan Adelaide desalination and expanded trading of water from the Murray-Darling Basin (MDB). What we present in this paper is a portfolio approach suggesting a mixed strategy of desalination and water trading to meet growing demand over the hundred year period from 2014. Crucially, the scope for expanding water trading keeps average costs down, for as long as the political agreements work and drought does not prevent the use of allocations. However, our modelling shows that in the long run water trade in combination with modular augmentation of desalination capacity can achieve a mix of security and cost that avoids spikes in market prices of MDB allocations during drought. The strategy also avoids the real business and household costs, loss of garden value and inconvenience of water restrictions.

Winners and Losers from the euro
This paper estimates the effect of having joined the monetary union on the income per capita of six early adopters of the euro using the synthetic control method. Our estimates suggest that while the income per capita of Belgium, France, Germany and Italy would have been higher without the euro, that of Ireland would have been considerably lower. The Netherlands is estimated would have been as well off without the euro. In addition, we use the insights from the literature on the economic determinants of the costs and benefits of monetary unions to explain these income effects. We find that early euro adopters with a business cycle more synchronized to that of the union, and more open to intra-union trade and migration lost less or gained more from the euro. A key role in the transmission of post-euro income losses across union members has been played by the integration of capital markets.

Spatial Aid Spillovers During Transition
We investigate whether development aid stimulates growth in transition economies, paying particular attention to the possibility of spatial spillovers arising from aid. We find that aid has a positive impact on growth of the recipient country. However, aid also appears to generate adverse growth spillovers on other nations. In contrast, we find significant positive spatial spillovers from good policies and there is some evidence that growth in one transition economy tends to spillover to bordering countries. Spillovers are an important part of the growth experience of transitional economies.

Market Efficiency in Asian and Australasian Stock Markets: A Fresh Look at the Evidence
Market efficiency is an important feature of successful financial markets. The aim of this paper is to analyze the available evidence on the efficient market hypothesis (EMH). Meta-regression analysis is applied to 1,560 estimates of the Variance Ratio test of the efficiency of Asian and Australasian stock markets. We test if there is evidence of violation of the EMH and we also explain the heterogeneity in the reported test results. Our meta-regression analysis specifically accommodates the possibility of publication selection in favor of accepting the null hypothesis of market efficiency. We find that Asian stock markets are, on average, not informationally efficient. However, market efficiency has improved over time and market capitalization and economic freedom influences stock market efficiency; more developed and less regulated stock markets are more efficient.

Aid and Institutions in Transition Economies
We investigate whether aid contributed to institutional development in transition economies. We find that aid flows have a positive effect on democratization, especially on constraints on the executive and political participation. At the same time, total aid has no effect on overall quality of governance, while US aid appears to have a negative impact on some dimensions of governance. Aids differential impact on democracy and governance is consistent with uneven development of institutions and the democracy consolidation hypothesis. We also find that aid has a non-linear effect on democracy. Openness has a positive effect on both democracy and good governance. Oil resources have an adverse effect on democracy. Adult mortality, civil war and adherence to Islam are all detrimental to good governance.

Breaking the Curse of Kareken and Wallace with Private Information
We study the endogenous choice to accept fiat objects as media of exchange and the implications for nominal exchange rate determination. We consider an economy with two currencies which can be used to settle any transactions. However, currencies can be counterfeited at a fixed cost and the decision to counterfeit is private information. This induces equilibrium liquidity constraints on the currencies in circulation. We show that the threat of counterfeiting can pin down the nominal exchange rate even when the currencies are perfect substitutes, thus breaking the Kareken-Wallace indeterminacy result. We also find that with appropriate fiscal policies we can enlarge the set of monetary equilibria with determinate nominal exchange rates. Finally, we show that the threat of counterfeiting can also help determine nominal exchange rates in a variety of different trading environments. These include a two-country setup with tradable and non-tradable goods sectors, and with an alternative timing of money injections.

There is much disparity in estimates of the income elasticity of air travel across the literature. We examine this disparity by applying meta-regression techniques. Controlling for several issues, including publication selection bias, while our preferred baseline income elasticity estimate of 1.186 is consistent with air travel being a luxury and a slightly immature market, there are several features of the literature which sway the income elasticity away from this baseline. For instance, the income elasticity increases to 1.546 on international routes, yet decreases to 0.633 when air fare is included in a dynamic specification of demand, ceteris paribus. Other characteristics of the literature, such as those involving various data and estimation choices, have less influence on the reported income elasticity.

Development Aid and Growth in Transition Economies
Empirical studies normally analyze diverse and heterogeneous groups of countries, producing very mixed evidence on the effectiveness of development aid in promoting growth. We focus on whether aid promotes economic growth in transitional economies. We find that aid, on average, has had a positive impact on growth for this specific group of countries. This result is robust to samples, estimators, and the use of alternate instruments to address endogeneity. Aid effectiveness is not conditional on good policy and there is little evidence of non-linear growth effects arising from aid.

Compensation of a Manager: The Case of Major League Baseball
In this paper, we are interested in the impact a Major League Baseball (MLB) manager has on a teams outcome. Using data on managers contracts, team performance, and team and manager characteristics, first, we determine the variables that determine a manager's salary. Then, we use a forecasting-type analysis to study the determinants of a managers performance, measured by winning percentage, attendance or playoff appearances. We find that a manager's past performance affects his current salary, but his current salary does not affect the team's performance. Our results support the lack of a competitive and efficient market for MLB managers.

Incorporating cultural values and preferences in wetland valuation and policy
This paper reports the findings of a choice modelling study designed to estimate the willingness-to-pay (WTP) for improvement of the ecosystem services of Bung Khong Long wetland in Thailand. The findings indicate that the cultural values associated with the wetland are significant suggesting that incorporating culture preferences may be a key factor in supporting wetland conservation. Attitudinal characteristics of respondents are important factors influencing WTP, implying community preferences are important in the effectiveness of environmental conservation efforts for this community.

Impatient in Experiments, but Patient in Simulations: A Challenge to a Neoclassical Model.
Despite ample empirical evidence on the prevalence of high discount rates among people, applied, quantitative-theoretical macro studies with exponential discounting often assume low positive, or even negative discount rate values. Relying on recent advances from the numerical optimal control branch of mathematics, we solve a neoclassical, continuous time model of endogenous consumption/saving and labor supply, and show that even if an agent has a moderately high discount rate, his labour supply and consumption behavior will be highly counterfactual. We provide a remedy to such counterfactual findings by augmenting a standard utility function based on recent evidences from the leisure sciences, while maintaining a rational choice approach of neoclassical economics.

Food Demand Elasticities for Australia
There is renewed interest in robust estimates of food demand elasticities at a disaggregated level not only to analyse the impact of changing food preferences on the agricultural sector, but also to establish the likely impact of pricing incentives on households. Using data drawn from two national Household Expenditure Surveys covering the periods 1998/99 and 2003/04, and adopting an Almost Ideal Demand System approach that addresses the zero observations problem, this paper estimates a food demand system for 15 food categories for Australia. The categories cover the standard food items that Australian households demand routinely. Own-price, crossprice and expenditure elasticity estimates of the Marshallian and Hicksian types have been derived for all categories. The parameter estimates obtained in this study represent the first integrated set of food demand elasticities based on a highly disaggregated food demand system for Australia, and all accord with economic intuition.

Career Interruptions: A Neglected Aspect of a Neoclassical Model
There is voluminous literature on the reasons behind career interruptions, ranging from maternity leave and organizational layoffs, to national service and human capital acquisition. We show that a standard, neoclassical model of intertemporal consumption/saving and labor/leisure choices without any friction can generate multiple career interruptions as a natural outcome of a consumption/leisure smoothing exercise performed by perfectly rational agents. Given the complexity of such a model, and to be consistent with traditions from the optimal control branch of mathematics, we use advances in numerical optimal control to solve a neoclassical problem.

Duration and Multidimensionality in Poverty Measurement
This paper unites two strands of the literature on subgroup decomposable poverty measurement originating from Foster, Greer and Thorbecke (1984) by incorporating information on both multiple dimensions and multiple periods. This generalises the Alkire and Foster (2011a) measure into a dynamic setting. In doing so, it introduces two variants of the transfer axiom: one that gives increasing weight to individuals whose deprivations are concentrated as repeated dimensions in a specific period (what we term breadth) versus one that gives increasing weight to individuals whose deprivations are concentrated as repeated periods in a specific dimension (length). The measure is able to differentiate between both aspects of poverty and consequently allows the assignment of different weights to each aspect. This makes it well suited to make comparison across subgroups when individual longitudinal data is available. We apply the proposed measure to longitudinal data from China where we compare differences in the estimate of poverty relative to existing measures.

Using product-level trade data, we empirically investigate the export patterns of more than 150 countries in their exports to the U.S., Brazil, India and Japan. We document strong evidence that exporters specialize according to their relative factor endowments, technology, and economic size. Moreover, developed, economically larger, and technologically-advanced countries are the major exporters of new products, spanning a wide range of product categories with high unit values. Our findings constitute a building block for the phenomenon that a large proportion of the global trade takes place among developed economies, and that the latter are also major exporters to developing markets.

The contractor game: a theoretical and experimental analysis
We introduce the contractor game , related to the ultimatum game (UG). The proposer makes an offer , and simultaneously sends a cheap talk message , indicating (possibly falsely) the amount of the offer. The responder observes the message with certainty and the offer with probability p before accepting or rejecting the offer. We theoretically examine versions with p = 0 and p = 0.5 along with the UG, played by some standard economic agents and others who are averse to inequity, lies and lying. The equilibria yield intuitive predictions, which are supported by our experimental results. Offers are higher when they might be seen by the responder. Messages overstate offers, but less so when the offer might be seen. Responders are more likely to accept an unseen offer if it might have been seen. When offers are seen, responders reward truthful messages, rather than punishing lies, compared to when no message is sent.

Formal and Informal Markets: A Strategic and Dynamic Perspective
In formal markets, to attract buyers, sellers must publicly advertise their prices and locations. But in informal markets, sellers must remain anonymous from government authorities. Since agents' payoffs depend on the ratio of buyers and sellers in each of these markets, all agents try to position themselves in the market which can yield them the highest possible payoff. This strategic interaction in turn critically affects the time evolution of these two markets. In our benchmark model, in which only sellers can switch between these markets, there exists a unique stable dynamic equilibrium where formal and informal markets co-exist. Sellers switch from the formal to the informal market whenever costs of trading in the informal market decrease, and vice versa. In a richer environment, where both sellers and buyers can switch between markets, and the sellers' and buyers' costs of trading in the formal market net of those in the informal market have opposite signs, there exists a unique stable dynamic equilibrium where formal and informal markets co-exist.
