Transaction taxes, greed and risk aversion in an agent-based financial market model

Recent agent-based financial market models came to the result that taxing financial transactions does not per se increase financial stability and that the response of volatility and misalignments to rising tax rates seem to be u-shaped. Moreover, greed and the risk appetite of traders are often blamed for financial instability and there is no evidence how greed and risk aversion affect the effectiveness of regulations in financial markets. We aim to add to this gap in the literature by analyzing how the effectiveness of transaction taxes depend on different behavioral patterns within an agent-based framework. Our simulations indicate that a tax rate of 0.1% demarcates the stabilizing tax regime from the destabilizing one. We figure out that transaction taxes are less effective, either when chartists trade more aggressively, fundamentalists trade less aggressively, agents switch more frequently between trading strategies or only have short memory in their fitness measures. Lower risk aversion of agents, however, makes higher tax rates more effective as indicated by a flatter volatility response curve. We conclude that additional regulations should concentrate on the traders’ responsibilities for their risk-exposure.     

Mind the channel! An affordance perspective on how digital voice channels encourage or discourage employee voice

We apply an affordance lens on qualitative data from three case organisations using a digital voice channel providing employees with the opportunity to speak up via answering periodic mini‐surveys and making comments in an anonymous mini‐forum. We find that imbrications of material and social agencies (i.e., the voice channel's features and managerial reactions to voice) in the respective organisational contexts culminate in employees perceiving the channel as either affording or constraining voice, leading to perceived voice outcomes that eventually encourage or discourage them to speak up. Whether voice is encouraged or discouraged partly results from the mere interaction between employees and the digital voice channel independent of managerial reactions. Our findings thus challenge the emphasis on managerial behaviour and reactions to voice in explaining voice behaviour and outcomes in extant literature.     

What do Russians think about transition?1

We use data from the 2006 round of the Russian Longitudinal Monitoring Survey to describe perceptions of the Russian population about the transition process and the role of the state compared with that of free markets. We find that about one‐half of the Russian population is disappointed with transition and a large majority is in favour of high state regulation and state provision of goods and services. High demand for government regulation and increased state intervention coexists with a low level of trust in government institutions and recognition of high and rising levels of corruption. The findings are consistent with the theory developed by Aghion et al. (2009) . In an environment with poor social capital, private business imposes negative externalities on the society and society chooses to demand more state regulation and tolerate corruption to reduce these externalities. We also find that individual perceptions of social capital and corruption co‐vary with the demand for regulation, as predicted by the theory.     

Distributional effects of imputed rents in five European countries

Most empirical distributional studies of well-being in developed countries rely on distributions of disposable income. From a theoretical point of view this practice is contentious since a household’s command over resources is determined not only by its spending power over commodities it can buy in the market but also on resources available to the household members through non-market mechanisms such as the in-kind provisions of the welfare state and the value of private non-cash incomes. In developed market economies the most important private non-cash income component is imputed rent from owner-occupied or subsidized accommodation. Employing a wider definition of imputed rent that also allows the analyst to capture income advantages among tenants living in rent-subsidized accommodations of various sorts (including rent-free or reduced-rent households), the present paper examines the differential effects of including imputed rents in the concept of resources in five European countries (Belgium, Germany, Greece, Italy and the UK). The results suggest that in almost all cases, the inclusion of imputed rents in the concept of resources leads to a decline in measured levels of inequality and poverty. The main beneficiaries are outright homeowners and households living in rent-free (or heavily subsidized) accommodation—most often older persons. The inclusion of imputed rents in the concept of resources does not lead to substantial changes in the ranking of the countries according to their level of inequality, despite widespread differences in the rates of home ownership and subsidization across the countries studied here.     

The perceived probability of job loss and future labour market outcomes

Longitudinal survey data are used to test the degree to which worker expectations of future job loss are correlated with changes in labour market status. Three major findings are reported. First, perceived probabilities of expected job loss are only weakly related to both exogenous job separations and subsequent transitions to unemployment and inactivity. Second, while fears of job loss tend to persist across time and job spells, they do so at a highly diminishing rate. Third, quit intentions are strongly correlated with both voluntary separations and transitions to alternative employment, and do not diminish greatly across successive employment spells.     

An interest rate peg might be better than you think

Active interest rate policy is frequently recommended based on its merits in reducing macroeconomic volatility and being a simple device. Yet, it might be outperformed by an even simpler policy. A peg can be welfare-enhancing and can uniquely be implemented.
