Export‐led growth and its determinants: Evidence from Central and Eastern European countries

In this study, we assess the importance of exports and global value chain (GVC) participation for economic growth. Using novel methods and an extensive data set, we decompose GDP growth in the Central and Eastern European countries (CEECs) to show that in a large part of the period of transition and integration with the EU, exports have played a predominant role in shaping economic growth. We also show that exports have been the major factor driving the convergence of the CEECs with their advanced counterparts. We employ panel methods to analyse the determinants of growth of exported value added and show that the major growth drivers in the analysed period of 1995–2014 are GVC participation, imports of technology and capital deepening.Jel classificationC23, F21, O33     

Selling information to competitive firms

Internal agency conflicts distort firms' choices and reduce social welfare. To limit these distortions, principals dealing with privately informed agents often acquire information from specialized intermediaries, such as auditing and certification companies, that are able to ascertain, and credibly disclose, agents' private information. We study how the structures of both the information provision and the final good markets affect information accuracy. A monopolistic information provider may supply imprecise information to perfectly competitive firms, even if the precision of this information can be increased at no cost. This is due to a price effect of information: although more accurate information reduces agency costs and allows firms to increase production, it also results in a lower price in the final good market, which reduces principals' willingness to pay for information.     

Poland’s uninterrupted growth performance: new growth accounting evidence

Since 1992 Poland has experienced an exceptionally long spell of output growth that was not interrupted even by the global economic crisis. Using a growth accounting exercise based on new estimates of flows of capital and labour services in the Polish economy during the period 1996–2013, we study the structure of this growth, highlighting the key role of certain supply-side factors. Most notably, unlike other European countries, the Polish economy recorded both a marked increase in capital deepening, a big improvement in workforce composition (driven mostly by educational attainment), and an uninterrupted process of productivity convergence. We also comment on the supply-side factors which contributed to Poland’s relative resilience to the global economic crisis of 2007–2010.     

“When Should Manufacturers Want Fair Trade?”: New Insights from Asymmetric Information when Supply Chains Compete

We study a model of competing manufacturer/retailer pairs where adverse selection and moral hazard are coupled with promotional externalities at the downstream level. In contrast to earlier models mainly focusing on a bilateral monopoly setting, we show that with competing brands a ‘laissez‐faire’ approach towards vertical price control might not always promote productive efficiency. Giving manufacturers freedom to control retail prices is more likely to harm consumers when retailers impose positive promotional externalities on each other, and the converse is true otherwise. Our simple model also suggests that, with competing supply chains, consumers and manufacturers might prefer different contractual modes if promotional externalities have substantial effects on demands.     

Wily welfare capitalist: Werner von Siemens and the pension plan

The German firm of Siemens and Halske introduced many enterprising features of what later came to be known as welfare capitalism in the mid-nineteenth century. Profit sharing, annual bonuses, a pension fund, a reduction in work hours, and an annual party were all means to ensure a productive, trouble-free workforce. We investigate the reasons why Siemens and Halske introduced this internal welfare system. We focus on the by-far most expensive part of the welfare system: the pension fund introduced in 1872, more than a decade before the nationwide social security system was implemented in Germany. We find that the adoption of the internal welfare system increased labor productivity, and in addition discouraged workers from striking. We estimate that the company’s gains due to strike prevention and higher productivity were at least as high as the cost of the pension fund. This suggests that (1) the introduction of a pension fund is not inconsistent with simple profit maximizing behavior on the firm’s side and (2) increased labor unionization induced firms to introduce subjective components of workers’ remuneration packages.     

Household resilience to adverse macroeconomic shocks: evidence from Czech microdata

We develop a methodology for identifying financially distressed households and use it for testing the responses to shocks to the unemployment rate, the interest rate and prices of essential expenditure in the Czech Republic. We extend the approach of Johansson and Persson (2006) for Sweden and Albacete and Fessler (2010) for Austria in the literature to allow for full labour market transitions between employment and unemployment, and, due to data availability, to account for heads and spouses within households. This improvement may lead to a higher response of household distress incidence, due to the unemployment rate shock, than in both Sweden and Austria, while the effects due to the interest rate shock are of similar size as in Austria. We illustrate the use of our approach for stress testing households’ ability to pay their debts using macroeconomic scenarios from the CNB’s official forecast and from the CNB’s Financial Stability Report. The results highlight the importance of using micro-level datasets in the analysis of household distress incidence, as the impact of shocks is more pronounced among lower-income households.     

Effect of electromagnetic field accompanying the magnetic resonance imaging on human heart rate variability – a pilot study

The effect of electromagnetic field on cardiovascular system in the literature is defined in ambiguous way. The aim of this study was to evaluate the effect of electromagnetic field on the heart rate variability (HRV) during the examination with magnetic resonance. Forty-two patients underwent Holter ECG heart monitoring for 30 minutes twice: immediately before and after the examination with magnetic resonance imaging (MRI). HRV was analysed by assessing a few selected time and spectral parameters. Is has been shown that standard deviation of NN intervals (SDNN) and very low frequency rates increased, whereas the low frequency:high frequency parameter significantly decreased following the MRI examination. These results show that MRI may affect the HRV most likely by changing the sympathetic-parasympathetic balance.     

Wasted waste: An evolutionary perspective on industrial by-products

Every production process gives rise to unintended outputs. We argue that whether an output is desired or undesired, is not given per se, but depends on the economic circumstances which change over time. As a result, by-products of one industry, first perceived as non-marketable wastes, may become desired inputs into other production processes. By adopting an evolutionary perspective on economic dynamics, in particular by exploiting the concept of niche exclusion, we identify favorable circumstances for undesired outputs to become marketable. To cope with the pace and unpredictability of economic evolution, we argue for a flexible policy system which favors outcome- over process-oriented waste management policies and balances the responsibility between consumers and producers on the one side, and the society as a whole on the other side.     

Communication,timing, and common learning

We study the effect of stochastically delayed communication on common knowledge acquisition (common learning). If messages do not report dispatch times, communication prevents common learning under general conditions even if common knowledge is acquired without communication. If messages report dispatch times, communication can destroy common learning under more restrictive conditions. The failure of common learning in the two cases is based on different infection arguments. Communication can destroy common learning even if it ends in finite time, or if agents communicate all of their information. We also identify conditions under which common learning is preserved in the presence of communication.     

Coordination of mobile labor

We study coordination failures in many simultaneously occurring coordination problems. Players encounter one of the problems but have the outside option of migrating to one of the remaining ones. Drawing on the global games approach, we show that such a mobile game has a unique equilibrium that allows us to examine comparative statics. The endogeneity of the outside option value and of the migration activity leads to non-monotonicity of welfare with respect to mobility friction; high mobility may hurt players. We apply these “general equilibrium’’ findings to the problem of the labor market during industrialization as described by Matsuyama [Increasing returns, industrialization and indeterminacy of equilibrium, Quart. J. Econ. 106 (1991) 617-650].
