Earnings inequality and the informal economy

We analyse the extent and evolution of informality and inequality in the Serbian labour market between 2002 and 2007, using data from the Living Standard Measurement Surveys. Two surprising results emerge. First, the level of informal employment has risen significantly over the period, despite strong economic growth and the introduction of a range of market‐oriented reforms. Secondly, the level of inequality in earnings seems to have remained more or less constant over the period, in contrast to the experience of other countries at a similar stage of transition. We show that informal employees earn significantly less than those in the formal sector, controlling for a range of other variables, and informality plays an increasingly important role in explaining earnings inequality.     

Environmental–Economic Accounting: Progress and Digression in the SEEA Revisions

The 1992 Earth Summit and its message of sustainable development drove the launching of a System for integrated Environmental and Economic Accounting, the SEEA. Since then, sustainable development and the SEEA have given way to green growth and green economy indicators in the latest 2012 Summit. A lengthy revision process has now produced a curtailed “SEEA central framework.” The new framework focuses on expenditures for environmental protection and resource management, and stocks and flows of “economic” resources; both are covered by the conventional national accounts. Environmental degradation, notably from pollution, is left to “experimental” ecosystem accounts. Further revision of the SEEA should reverse this retrenchment from integrative environmental–economic accounting. A comprehensive satellite system, rather than a limited statistical standard, might put the SEEA back on the policy agenda.     

Excessive Volatility is Also a Feature of Individual Level Forecasts

The excessive volatility of prices in financial markets is one of the most pressing puzzles in social science. It has led many to question economic theory, which attributes beneficial effects to markets in the allocation of risks and the aggregation of information. In exploring its causes, we investigated to what extent excessive volatility can be observed at the individual level. Economists claim that securities prices are forecasts of future outcomes. Here, we report on a simple experiment in which participants were rewarded to make the most accurate possible forecast of a canonical financial time series. We discovered excessive volatility in individual-level forecasts, paralleling the finding at the market level. Assuming that participants updated their beliefs based on reinforcement learning, we show that excess volatility emerged because of a combination of three factors. First, we found that submitted forecasts were noisy perturbations of participants’ revealed beliefs. Second, beliefs were updated using a prediction error based on submitted forecast rather than revealed past beliefs. Third, in updating beliefs, participants maladaptively decreased learning speed with prediction risk. Our results reveal formerly undocumented features in individual-level forecasting that may be critical to understand the inherent instability of financial markets and inform regulatory policy.     

Actors, resources, activities and commitments

A new concept, commitments, is introduced and defined as “agreements between two or more social actors to carry out future actions” and its incorporation into, and articulation of, the actors-resources-activities model described. Commitments are distinguished from the concept of commitment as traditionally used in inter-organisational relationships. The latter is mainly an affective measure at the level of an individual concerning the general relationship between buying and selling organisations. By contrast commitments are agreements made between actors and range from the specific and everyday to the general and strategic.The theoretical background and nature of commitments are described and how commitments relate to and enrich each of the elements of the ARA model demonstrated. The application of the concept to B2B relationships at the level of individual, group, organisational and net actors is set out and implications of the use of the commitments concept for researchers and managers are suggested.     

A multivariate analysis of work–life balance outcomes from a large‐scale telework programme

A multivariate analysis identified six predictors to explain positive work–life balance (WLB) among 1,566 teleworkers. Time flexibility variables were found to be most dominant. Gender or having dependent children was not significant. These results demonstrated that controlling working hours was the most important ability for sampled teleworkers to achieve positive WLB.     

Contribution of financial market segments at different stages of development: Transition,cohesion and mature economies compared

What is the impact of financial sector segments at different stages of development? We apply a production function approach to investigate the impact of the credit, bond and stock segments in nine EU-accession countries over early years of transition (1996–2000) and compare these to mature market economies and to countries at intermediate stage. We find that the transfer mechanisms differ over the development cycle (from bond markets to educational attainment to labor participation) and that financial market segments with links to the public sector (but not stock markets) contributed to stability and growth in transition economies.     

Comment on the Kannai-Peleg impossibility theorem for extending orders

Recent work by Y. Kannai and B. Peleg shows that two appealing axioms for extending a linear order on a set of six or more elements to a weak order on the family of non-empty subsets of that set are mutually incompatible. This comment shows that a modest restriction of their monotonicity axiom is compatible for extension with a generalization of their other axiom provided that the linear order on the basic set is a well ordering.
