Demonstration of power: Experimental results on bilateral bargaining

We test the empirical effectiveness of two theoretical proposals to equilibrate bargaining power in bilateral bargaining. Our experimental design is based on the two-player versions of the multibidding game (Pérez-Castrillo & Wettstein, 2001) and the bid-and-propose game (Navarro & Perea, 2005). Both models build on the ultimatum game and balance parties’ bargaining power by auctioning the role of the proposer in the first stage. We find that proposers learn how to send an acceptable proposal by trial and error, guided by responders’ rejections. The observed behavior stabilizes for the final experimental rounds and the payoff gap between the proposer and the responder seems to close down. However, the strategies chosen by subjects are remarkably different from the theoretical ones.     

An exploratory analysis of composite choices: Weighing rationality versus irrationality

Humans are engineered neurologically to make rational and irrational choices. This paper introduces a new paradigm for decision making – a composite choice model – in which economic agents are constantly weighing rationality versus irrationality when encountering options. In an exploratory, deterministic, two-period model, an assumption of a two-way cross-embedment (i.e., a two-way interaction between the rational and irrational components) results in a paradoxical phenomenon, an outcome of either tending toward bliss or abyss at the end of the first period. This implies, for instance, a psychological struggle between two selves within the mind. The paradigm proposed is compared to the dual-process theories recently developed by the cognitive sciences. Future research will explore implications for public policy design and implementation.     

Characterizations based on record values and order statistics

Consider a sequence of independent and identically distributed random variables {_Xi,i?1}$\{X_i,i?1\}$ with a common absolutely continuous distribution function F  . Let _X1:n?_X2:n???_Xn:n$X_{1:n}?X_{2:n}???X_{n:n}$ be the order statistics of {_X1,_X2,…,_Xn}$\{X_1,X_2,\dots ,X_n\}$ and {_Yl,l?1}$\{Y_l,l?1\}$ be the sequence of record values generated by {_Xi,i?1}$\{X_i,i?1\}$. In this work, the conditional distribution of _Yl$Y_l$ given _Xn:n$X_{n:n}$ is established. Some characterizations of F   based on record values and _Xn:n$X_{n:n}$ are then given.     

Higher order moments of order statistics from INID symmetric random variables

In this paper we present analogues of Balakrishnan's (1989) relations that relate the triple and quadruple moments of order statistics from independent and nonidentically distributed (I.NI.D.) random variables from a symmetric distribution to those of the folded distribution. We then apply these results, along with the corresponding recurrence relations for the exponential distribution derived recently by Childs (2003), to study the robustness of the Winsorized variance.

Replication: Emotional well-being and unemployment – Evidence from the American time-use survey

We use data from the well-being module of the American Time-Use Survey (ATUS) 2010–2013 to reexamine the relationship between unemployment and emotional well-being. We replicate two previous studies (Krueger & Mueller, 2012; Dolan, Kudrna, & Stone, 2017) which have produced differing findings on this relationship, and analyze what factors cause the differences in their outcomes. We find that the results critically depend on the definition of employment statuses and the choice of well-being measure. The unemployed appear sadder and more in pain than the employed, but no other emotion queried in the ATUS has worse values for the unemployed than for the employed. Aggregate emotional well-being measures suggest that unemployment is not negatively related to emotional well-being. Applying a wider instead of narrow definition of unemployment tends to result in better emotional well-being scores for the unemployed, mainly because job leavers and new or re-entrants into the labor market report better emotions than the group of people who are unemployed due to an involuntary job loss.     

Measures of individual risk attitudes and portfolio choice: Evidence from pension participants

We use a large non-student sample to test how distinct measures of risk-attitudes relate to each other, to demographic characteristics and to real-life risk taking in the financial domain. These measures, namely the Bomb Risk Elicitation Task (BRET), self-reported willingness to take risks in general, the choice in a hypothetical lottery, the score in the Domain Specific Risk-Taking (DOSPERT) scale, appear to be positively correlated and exhibit a certain degree of consistency. Furthermore, a subset of these measures is driven by similar demographic characteristics as such that males are more risk seeking and risk-aversion increases with age. Using extensive data on the retirement portfolios of the participants during the years 2008–2014, we find that all of these measures are positively correlated with the riskiness of individual portfolios. The self-reported willingness to take risks in general appears to be the most relevant measure in predicting actual risk-taking behavior.     

Analysis of child labour in Peru and Pakistan: A comparative study

This paper analyses child labour participation and its key determinants using data sets from Peru and Pakistan. The results include tests of the ‘Luxury’ and ‘Substitution’ hypotheses that play key roles in recent studies on child labour and child schooling. The results reject both hypotheses in the context of child labour in Pakistan and suggest that income and related variables do not have the expected negative effect on children's work input. Rising wages of adult female labour in Pakistan, and falling adult male wage in Peru lead to increased participation of children in the labour market. The results on the combined country data formally establish the presence of strong individual country effects in the estimated regressions. For example, ceteris paribus, a Peruvian child is more likely to experience schooling than a Pakistani child. However, both countries agree on the positive role that adult female education and infrastructure investment in basic amenities can play in discouraging child labour and encouraging child schooling.
