The Emergence of Non-monetary Means of Payment in the Russian Economy

The widespread use of non-cash payments in Russia is the result of a complex bundle of factors: tax evasion, established networks of enterprises and policy-induced causes. By use of non-monetary payments, agents have relaxed their liquidity constraints, but they still lack the financial resources needed to undertake investment and restructuring. Banks' credit provision is based on criteria other than the profitability of the recipient of the funds. The interest rate, coupled with the restructuring of the banking sector, could operate as an effective lever that may lead to a more economically consistent management of liquidity and could also reduce capital flight.     

Conditional Value-at-Risk,spectral risk measures and (non-)diversification in portfolio selection problems – A comparison with mean–variance analysis

We study portfolio selection under Conditional Value-at-Risk and, as its natural extension, spectral risk measures, and compare it with traditional mean–variance analysis. Unlike the previous literature that considers an investor’s mean-spectral risk preferences for the choice of optimal portfolios only implicitly, we explicitly model these preferences in the form of a so-called spectral utility function. Within this more general framework, spectral risk measures tend towards corner solutions. If a risk free asset exists, diversification is never optimal. Similarly, without a risk free asset, only limited diversification is obtained. The reason is that spectral risk measures are based on a regulatory concept of diversification that differs fundamentally from the reward-risk tradeoff underlying the mean–variance framework.     

Multinational Firms and Labor Market Pooling

In the presence of increasing specialization of workers it becomes more and more difficult for firms to find the most suitable workers. In such an environment a multinational enterprise (MNE) has an advantage because it can exchange workers between plants in different countries. Recruiting from the home and foreign plant leads to a larger labor market pool for an MNE, reducing the mismatch of its workforce. This paper analyzes the consequences of this advantage for production, employment, prices and wages. In line with recent empirical results, we find that the additional ability to recruit workers from the home and foreign labor market leads to lower mismatch, higher average productivity of workers, lower prices, higher output, and higher employment of a plant of an MNE as compared with a national firm, while the wage‐effects depend on firm productivity.     

The contribution of trout fly fishing to the economy of Rhodes,North Eastern Cape,South Africa

Recent government legislation, which calls for the eradication of trout from ecosystems where they may cause harm, could damage the tourism appeal of many South African catchments. However, no South African studies have tried to quantify the economic impact of removing trout from rivers and streams. This study aimed first to value the Rhodes trout fishery, North Eastern Cape, South Africa, and second to assess whether the trout fly fishing industry in Rhodes could form the foundation for the implementation of a local economic development initiative. Overall, the study found that the trout fishing industry directly generates approximately R5 658 240 per annum, and sustains a minimum of 39 direct job opportunities for the community of Rhodes, and can therefore provide the impetus for the creation of a tourism-based local economic development programme.     

A MATHEMATICAL APPROACH TO HARROD'S OPEN ECONOMY DYNAMICS

This paper investigates an open economy dynamic model in the Harrod tradition. Its goal is to check if in accordance with Harrod's thought, opening to foreign trade is able to reduce the cyclical instability the economic system exhibits when it is closed to the international trade. We show that the system's dynamic behavior depends on changes in the saving rate, the competitiveness of home products in the foreign markets and the initial sign of the balance of trade. We demonstrate that stable cycles are possible only under particular conditions. Otherwise, the economy may experience chaotic motions in the long period.     

A General Approach to Rational Learning in Games

This paper provides a general framework for analysing rational learning in strategic situations in which the players have private priors and private information. The author analyses the behaviour of Bayesian rational players both in a repeated game and in a recurrent game when they are uncertain about opponents' behaviour and the game they are playing. The aim of the paper is to explain how Bayesian rational agents learn by playing and to characterize the outcome of this learning process. By studying the concept of 'conjectural equilibrium' and analysing the process of convergence of players' behaviour, the roles played by the notions of merging and of consistency are demonstrated.     

Do unemployment benefits promote or hinder job reallocation?

According to recent and largely untested theories, unemployment benefits (UBs) could improve the extent and quality of job reallocation even at the cost of increasing unemployment. In this paper, we use a new set of yearly panel data from a large number of countries to evaluate empirically the relationship between unemployment benefits and job reallocation. Unlike previous work assessing the effects of UBs on labor market stocks, we focus on flows and rely on policy “experiments,” notably the introduction from scratch of unemployment benefits in many countries. We exploit the longitudinal nature of our data to lessen the potentially important selection, endogeneity, and omitted variable problems. We find a positive, sizable, and significant effect of the introduction of UBs on job reallocation, arising mainly from the job destruction margin although this effect fades away over time. These findings appear to be robust to changes in the countries in the sample, control variables or estimation methods. We discuss to what extent our results are consistent with equilibrium matching models with or without endogenous sorting of workers into jobs providing entitlement to UBs and stochastic job matching.     

Designing foresight studies for Nanoscience and Nanotechnology (NST) future developments

Nanoscience and Nanotechnology (NST) is widely considered as one of the most promising areas of scientific and technological development for future decades. As a consequence, almost every country in the world has chosen to invest significantly in this area. This choice, however, is only a first step in the investment decision process, given that almost any scientific discipline can be taken at the scale of a nanometre. In this paper, it is argued that foresight studies to decide where to invest in the nanotechnology area should be designed in a different way from what is normally done. Nanotechnology, in fact, has specific characteristics that should be taken into account when evaluating its expected impacts and potentialities.     

Coordinating the accumulation of physical and human capital in different institutional settings

This paper presents an out-of-equilibrium model to explain differences in the capacity to absorb new skill-biased technologies. The usual mainstream viewpoint focusing only on the role of labour markets will be re-examined in a context characterized by a sequential structure of both the processes of production and the skill formation, whose interaction brings about coordination failures harming the viability of the innovation process. Our out-of-equilibrium approach allows us to consider the more general interplay between stylized labour and product market characteristics, on the one hand, and educational policies, on the other hand. The robust results of the simulations show that educational policies appear to be important in restoring the required coordination both in rigid and in flexible systems, but for different reasons. In the former case, educational policies financed by taxation allow the system to escape a low-productivity final equilibrium. In the latter case, they contrast the financial constraint associated with a large decrease in the unskilled wage. Altogether, a moderate degree of rigidity seems to be the most appropriate institutional environment to reach the targets of viability and of a full exploitation of the technological potential.
