Cantor’s Diagonal Argument: An Extension to the Socialist Calculation Debate—A Comment

In a recent article Robert P. Murphy (2006) uses Cantor’s diagonal argument to prove that market socialism could not function, since it would be impossible for the Central Planning Board to complete a list containing all conceivable goods (or prices for them). In the present paper we argue that Murphy is not only wrong in claiming that the number of goods included in the list should be uncountable, but also that the number of equations/prices is irrelevant from the point of view of market socialism.

Effects of treatment beyond the treated: a general equilibrium impact evaluation of Lesotho's cash grants program

Africa's social cash transfer programs target the most resource‐constrained households, unlikely to expand supply in response to transfer‐induced demand. We propose a local economy‐wide impact evaluation model and use it to evaluate local spillovers from Lesotho's Child Grants Program. We report Monte‐Carlo confidence bounds around impact‐simulation results. We find significant spillovers to nonrecipient households and significant real income multipliers, although the latter are dampened if factor supply constraints generate excessive inflationary pressures. Our findings raise questions about how to measure the impacts of cash transfers. Evaluations focusing only on eligible households are likely to significantly understate program impacts.     

Links between trust in the ECB and its interest rate policy

We analyse determinants of trust in the European Central Bank (ECB). Our main finding is that when households have pessimistic expectations, aggressive cuts in interest rates have an adverse effect on their trust in central bank. This result is in accordance with the ‘lack-of-confidence shock’ hypothesis developed by Schmitt-Grohé and Uribe (2012) and in contrast with the ‘fundamental shock’ hypothesis which implies positive effects of aggressive cuts for trust in the ECB. The result is robust to various changes in the modelling approach.     

PRACTICAL TOOLS FOR POLICY ANALYSIS IN DSGE MODELS WITH MISSING SHOCKS

In this paper we analyze the propagation of shocks originating in sectors that are not present in a baseline dynamic stochastic general equilibrium (DSGE) model. Specifically, we proxy the missing sector through a small set of factors that feed into the structural shocks of the DSGE model to create correlated disturbances. We estimate the factor structure by either matching impulse responses of the augmented DSGE model to those generated by an auxiliary model or by using Bayesian techniques. We apply this methodology to track the effects of oil shocks and housing demand shocks in models without energy or housing sectors. Copyright © 2014 John Wiley & Sons, Ltd.     

Wealth inequality in Central and Eastern Europe: Evidence from household survey and rich lists’ data combined*

We study how the problem of the ‘missing rich’, the underrepresentation of the wealthiest in household surveys, affects wealth inequality estimates for the post‐socialist countries of Central and Eastern Europe (CEE). The survey data from the second wave of the Household Finance and Consumption Survey (HFCS) are joined with the data from the national rich lists for Estonia, Hungary, Latvia, Poland and Slovakia. Pareto distribution is fitted to the joined survey and rich lists’ data to impute the missing observations for the largest wealth values. We provide the first estimates of the top‐corrected wealth inequality for the CEE region in 2013/2014. Despite a short period of wealth accumulation during the post‐1989 market economy period, our adjustment procedure reveals that wealth inequality in the Baltic countries is comparable to that of Germany (one of the most wealth‐unequal countries in Europe), while in Poland and Hungary it has reached levels observed in France or Spain. We discuss possible explanations of these findings with reference to the speed and range of privatization processes, extent of income inequality, and the role of inheritances and wealth taxes in the region.     

Transmission of monetary policy and exchange rate shocks under foreign currency lending

This paper analyses the differences in reaction of domestic and foreign currency lending to monetary and exchange rate shocks, using a panel VAR model estimated for the three biggest Central and Eastern European countries (Poland, the Czech Republic and Hungary). Our results point toward a drop in domestic currency loans and an increase of foreign currency credit in reaction to monetary policy tightening in Poland and Hungary, suggesting that the presence of foreign currency debt weakens the transmission of monetary policy. A currency depreciation shock leads to an initial decline in foreign currency lending, but also in loans denominated in domestic currency as central banks react to a weaker exchange rate by increasing the interest rates. However, after several quarters, credit in foreign currency accelerates, indicating that borrowers start using it to substitute for depressed domestic currency lending.     

Risk management system in business relationships—Polish case studies

The article discusses the problem of risk management in business relationships. The authors' research (including a case study analysis of 5 different relations) enabled them to identify and characterize the risk management systems based on a combination of formal control and relational mechanisms. In the authors' research it has been assumed that relational risk has a negative influence on the cooperation results and therefore it should be a subject of management. The main objective is not to avoid taking risk in relationships, but to reduce it to the minimum possible level. Companies' cooperation, including partnerships with different entities and participation in business networks, is an immanent characteristic of contemporary business. Therefore managers should look for the most efficient methods of dealing with additional relational risk and opportunistic behavior of potential partners.In the paper the case study analysis of five relationships of companies operating on Polish market was presented. The main objective was to demonstrate the relation between the level of trust and the intensity of formal control (including contract and formal monitoring). The range of social control applied in analyzed relationships was also an important issue of consideration.The research presented in the paper indicated that companies located in Poland in order to reduce relational risk aimed at diversification of its partners or full integration. Managers often underlined their fear of being dependent on one particular partner. This phenomenon could comprehensively decrease the advantages of intensive and deepened inter-organizational cooperation in Poland. Furthermore, the research demonstrated the decisive role of relational mechanisms and limited significance of contract in business relationship risk management. However, relatively higher importance of contract was observed in unbalanced relations between partners representing diverse bargaining power. A positive relationship between application of relational tools and cooperation results was identified as well.The aim of the paper is to demonstrate the nature of the relationship risk management system and the role of particular mechanisms that enable to reduce risk and its negative influence on cooperation results.     

Some approximations of n-copulas

We consider several approximations to n-copulas: the checkmin, checkerboard, Bernstein, and shuffle of min approximations. The checkerboard, Bernstein, and shuffle of min approximations have been studied in the n = 2 case. We investigate these constructions in arbitrary finite dimensions and consider some of the ways in which they converge or fail to converge to the original copula.
