Choice and self: how synchronic and diachronic identity shape choices and decision making

Research on the role of identity in choice varies widely across fields like psychology, philosophy, consumer behavior, and economics, in both the key questions addressed and the methods of investigation. Although a large literature has established how salient aspects of identity affect attitudes and norms, less is known about how beliefs concerning identity are shaped and how these beliefs affect decision making. In this review, we cover recent insights into these issues and summarize some newer, developing approaches to understanding (i) how people judge the persistence of identity, (ii) how beliefs about future changes in identity are formed and how they affect choices, (iii) the formation of beliefs about future changes in identity and how these beliefs affect decisions, and (iv) the historical and economic antecedents of identity norms and their consequences for economic behavior. We introduce a distinction between synchronic and diachronic approaches, and highlight important unresolved questions that will help these fields to more fully understand the role that identity plays in shaping choices.     

Alliances and negotiations: an incomplete information example

We study a bargaining game between an individual and an ‘alliance’ in the sense of Manzini and Mariotti (J Econ Theory 121:128–41, 2005), in which the opponent of the alliance is incompletely informed about the relative strengths of its members. The best equilibrium outcome for the alliance under a unanimity rule is not attainable with a non-unanimity rule. However, unlike in the complete information model, less than optimal outcomes and delays may occur with positive probability even under unanimity, depending on the prior beliefs and the preferences of the agents. We are grateful to a careful referee for comments. We wish to thank Clara Ponsati for useful comments.     

Hours worked in selected OECD countries: an empirical assessment

In this paper, we empirically assess the evolution of the aggregate hours worked, with a particular emphasis on their age structure, in a sample of OECD countries, along the period 1970–2007. We show that the age composition of the workforce has a large and statistically significant effect on hours worked volatility. To exploit the multilevel structure of our data, we use a Mixed Linear Model to investigate the consequences of (i) demographic change, (ii) sector-specific, and (iii) country-specific factors on hours worked by ‘young’ (aged 15–29) and ‘prime-aged’ (29+) individuals. We show that changes in workforce demographics, captured by the ratio between population older than 29 and population younger than 29, are strongly and significantly correlated with the amount of hours worked by ‘young’ individuals. We also document the impact of sectoral capital intensity and profitability on the dynamics of (aggregate) hours worked. Finally, we show that productive public expenditure, here proxied by the public investment in ICT, is beneficial for the hours worked both by young and prime-aged individuals.     

Do micro start-ups fuel job creation? Cross-country evidence from the DynEmp Express database

Exploiting a novel database recently built from national business registers by the OECD with the support of an international network of experts, this paper investigates the growth dynamics of micro-firms (employing less than ten workers) across 16 countries. Results show that only a small proportion of micro-firms manage to grow beyond ten employees, but those contribute disproportionately to overall job creation. Econometric analysis focusing in particular on the role of age confirms that young micro-firms—especially those below 3 years of age—are much more likely to grow above ten employees than older firms. These findings are remarkably stable over the three time periods considered (2001–2004, 2004–2007, and 2007–2010), i.e., also during the Great Recession.     

Why are more redistributive social security systems smaller? A median voter approach

One of the stylized facts of unfunded social security programsis that programs are larger in size, measured relative to theGDP, the tighter the link between pension claims and past earnings.We provide a political economy explanation of this stylizedfact in a median voter model, where people vote on the socialsecurity tax rate. We compare pension systems with flat-rateand earnings-related benefit formulas. Only flat-rate benefitsredistribute within a generation from high to low income groups.If labor supply is endogenous, they also imply larger efficiencycosts than earnings-related schemes. Using data on eight Europeancountries, we find that the median voter is typically middle-agedwith high income. For these voters, earnings-related systemsare more attractive both because of less intragenerational redistributionand lower distortions in labor supply. The median voter modelis also able to account for a considerable degree of cross-countryvariation in contribution rates.     

Productivity, exporting, and the learning-by-exporting hypothesis: direct evidence from UK firms

Abstract.  Case studies suggest exporters learn from clients. Econometric evidence is mixed. We use firm-level panel data on exporting and productivity with direct information on learning sources, including clients. We find: (a) firms who exported in the past are likely to learn more from clients (relative to other sources); (b) firms who learned from clients in the past are more likely to have faster productivity growth; (c) the reverse is not the case; that is, past productivity growth is not associated with more learning from clients and past learning from clients is not associated with more exporting. These results are consistent with the learning-by-exporting hypothesis.     

Studio delle eliminazioni da una collettività per più case con il metodo simulativo

Vengono messe in luce alcune problematiche che si presentano quando si applichi il metodo della simulazione stocastica allo studio dell'evoluzione nel tempo di collettività chiuse ed unitarie esposte a più cause di eliminazione. Viene poi proposta un'impostazione che unifica i diversi punti di vista adottati in recenti lavori sull'argomento.

Summary We investigate some problems that are met when studying by stochastic simulation the evolution over time of a (closed and homogeneous) collectivity underlying to more than one cause of elimination, and propose a unifying viewpoint on the argument.

     

Alliances and negotiations

Negotiations often occur not between individuals but among groups (companies, trade unions, political parties, etc.) each representing composite interests, whose bargaining behaviour is regulated by some collective decision mechanism. In this paper we provide a natural model of such circumstances. We formalise the notion of ‘alliance’ and show how different preference aggregation procedures within the alliance affect the bargaining outcome. In particular, we find that unanimity procedures lead to ‘more aggressive’ negotiating tactics than majority procedures.     

How financial information disclosure affects risk perception. Evidence from Italian investors’ behaviour

This paper investigates how different representations of financial information may be appraised in terms of complexity and usefulness, and how financial disclosure influences individuals’ risk perception. By using a consumer testing analytical approach, we run a survey on a sample of Italian investors: 254 bank customers were submitted 4 different templates, each combining a different typology of data (historical and prospective) and framing (words, numbers and charts) to indicate the same level of risk and return of four real-life financial instruments. Representation formats partially overlap with those mandated by regulators and used within the financial industry. Results show that the perceived riskiness of financial products is affected by the way information is disclosed. Perceived complexity of the financial information disclosure intensifies perception of riskiness of the product solicited. Gender, age, personal traits, behavioural biases and financial knowledge, do also play a role. Overall, given investors’ heterogeneity and behavioural biases, neither simplifying disclosure nor a ‘one-size-fits-all’ approach may be sufficient to ensure correct risk perception and to prevent unbiased investment choices.
