Competition and Scope of Activities in Financial Services

This article analyzes the costs and benefits of different degreesof competition and different configurations of permissible activitiesin the financial sector and discusses the related implicationsfor regulation and supervision. Theory and experience demonstratethe importance of competition for efficiency and confirm thata competitive environment requires a contestable system—meaningone that is open to competition—but not necessarily alarge number of institutions. A competitive banking system canimprove the distribution of consumer credit, enhance the corporatesector's access to financing, and mitigate the risks of financialcrises. In an open market, in which services and products areprovided in response to market signals, financial institutionsrespond by offering a wider scope of financial services. Theoptimal institutional design for supervisory functions is lessobvious.      

Re-estimating gender differences in income in South Africa: The implications of equivalence scales

Most studies of poverty and inequality in South Africa measure individual welfare by deflating total household resources, such as income, by household size. This per-capita method makes no adjustments for the different consumption needs of children or for household economies of scale. However, in addition to being more likely to live in households where average per-capita household income is lower compared with men, we show that women in South Africa also live in significantly larger households which include more children. These gendered differences in household composition are driven to a large degree by low rates of co-residency between men and women. We therefore investigate how adjusting household resources for the presence of children and economies of scale affects measures of the gender gap in income.     

Expected future earnings,taxation, and university enrollment

Taxation changes the expectations of prospective university students about their future level and uncertainty of after-tax income. To estimate the impact of taxes on university enrollment, we estimate a structural microeconometric model, in which a high-school graduate decides to enter university studies if expected lifetime utility from this choice is greater than that anticipated from starting to work right away. We estimate the ex-ante future paths of the expectation and variance of after-tax income for German high-school graduates, accounting for nonrandom selection. The enrollment model takes into account university dropout and unemployment risks. Consistently with expectations, the estimation results indicate that higher expected returns to a tertiary education increase the probability of university enrollment, whereas higher uncertainty among graduates decreases enrollment rates. A simulation based on the estimated model indicates that a revenue-neutral, flat-rate tax reform with an unchanged basic tax allowance would increase enrollment rates for men in Germany.     

INCOME TAXES AND THE COMPOSITION OF PAY: EVIDENCE FROM THE BRITISH HOUSEHOLD PANEL SURVEY

According to the standard principal‐agent model, the optimal composition of pay should balance the provision of incentives with the individual demand for insurance. Do income taxes alter this balance? We show that the relative share of Performance‐related pay (PRP), on total pay is reduced by higher average and marginal income taxes. Empirical evidence based on the British Household Panel Survey is consistent with the theoretical predictions of the tax–augmented principal‐agent model. Our estimates suggest that a 10% reduction in the marginal income tax rate, holding the average tax rate constant, increases the share of PRP in total pay by 2.25–3.02%, depending on the empirical specification. Similarly, a 10% reduction in the average income tax rate, holding the marginal tax rate constant, increases the share of PRP in total pay by 5.10–5.27%.     

Productivity Dispersion and its Determinants: The Role of Import Penetration

The new heterogeneous firm models in international economics predict a negative impact of trade openness on within-sector productivity disparities, due to a restructuring process leading to a reallocation of resources towards more efficient firms and the exit of less productive ones. I test this hypothesis for the Italian manufacturing sectors making use of panel data models. I investigate the existence of heterogeneous effects in terms of origin of imports and I account for a geographical dimension computing the productivity dispersion indicator by sector and regional macro-area. The analysis is implemented within a comprehensive framework controlling for other potential determinants, such as technological factors and domestic competition. My findings show that competitive pressure from low income countries reduces the productivity heterogeneity across firms. On the contrary, a positive impact is detected for the increased availability of intermediates originating from developed countries.     

Chaos and the exchange rate

Chaotic exchange rate models are structural models built in discrete time (difference equations), and show that with orthodox assumptions (PPP, interest parity, etc) and introducing plausible nonlinearities in the dynamic equations, it is possible to obtain a model capable of giving rise to chaotic motion. However, none of these models is estimated, and the conclusions are based on simulations: the empirical validity of these models is not tested. In this paper, a continuous time (the exchange rate is obviously a continuous variable) exchange rate model is built as a non-linear set of three differential equations and its theoretical properties (steady state, stability, etc,) analysed. The model is then econometrically estimated in continuous time with Italian data and examined for the possible presence of chaotic motion. This paper also shows that the continuous time estimation of economic models built as systems of nonlinear differential equations is a very powerful tool in the hands of the profession.     

Adaptive aspirations and performance heterogeneity: Attention allocation among multiple reference points

Organizations learn and adapt their aspiration levels based on reference points (prior aspiration, prior performance, and prior performance of reference groups). The relative attention that organizations allocate to these reference points impacts organizational search and strategic decisions. However, very little research has explored this. Therefore, we build a recursive feedback model of learning from organizational experience that explains heterogeneity of attention allocation to the reference points in adaptive aspirations. In a sample of the German magazine industry (1972–2010), we find when early in their life cycle and as they or their parent company age, organizations tend to focus more on their own aspirations; however, when at the verge of bankruptcy, they increase their attention to competitors' performance.
