Inflationary finance in an open economy

Models of inflationary finance that consider trade and capital flows generally conclude that openness curtails the ability of governments to impose the inflation tax due to currency substitution. This paper models two channels that allow central banks to increase inflation tax revenue by opening the economy. First, central banks can open the capital account subject to a reserve requirement on capital inflows. Revenue maximization produces a smaller reserve requirement on foreign capital inflows that on domestic deposits. Second, central banks can impose prior import deposits to broaden the monetary base in order to use the inflation tax on imports as an alternative to tariff revenue.     

Policy Instruments for Groundwater Management in the Netherlands

In the Netherlands agriculture andnature have conflicting interests with respectto groundwater management. Insight into thesuitability of policy instruments to achieveoptimal groundwater level and extractionmanagement in the Netherlands is, however,missing. In this paper the suitability ofpolicy instruments for groundwater managementis studied. Changes in the institutionalenvironment and voluntary agreements seem to bemore suitable for groundwater level managementthan economic instruments. The currenthistorical groundwater extraction rightssystems together with the low groundwaterprices encourage low-value agriculturalgroundwater usage, whereas sprinkling bans andirrigation scheduling currently aim to reducelow-value use of groundwater. These extractioninstruments are less efficient than a systemthat considers externalities in the price ofwater or diverts water away from agriculturewhile encouraging trading.     

Estimates of real economic activity in Switzerland, 1886–1930

This paper uses annual data spanning 1870 to 1930 on a set of variables correlated with business conditions to construct an index of real economic activity in Switzerland. We extract an estimate of the common component of the data series using principal components analysis and the unobservable variables approach proposed by Stock and Watson (1989, 1991). The resulting index is similar to that constructed by Andrist et al. (2000) but displays more variation over time and is available for a longer time period. Moreover, it is less volatile and covers a longer time period in the 20th century than the estimate by Ritzmann-Blickenstorfer (1996).First version received: May 2002/Final version received: September 2004The views expressed in this paper are solely our own and are not necessarily shared by the institutions we are affiliated with. We thank the Editor and the anonymous referees for helpful comments (in particular for finding serious errors in the principal components analysis), and Jim Stock and Mark Watson for detailed explanations of their estimation strategy.     

RETRACTED ARTICLE: Prediction of economic growth by extreme learning approach based on science and technology transfer

The purpose of this research is to develop and apply the extreme learning machine (ELM) to forecast gross domestic product (GDP) growth rate. Economic growth may be developed on the basis on combination of different factors. In this investigation was analyzed the economic growth prediction based on the science and technology transfer. The main goal was to analyze the influence of number of granted European patents on the economic growth by field of technology. GDP was used as economic growth indicator. The ELM results are compared with genetic programming (GP) and artificial neural network (ANN). The reliability of the computational models were accessed based on simulation results and using several statistical indicators. Coefficient of determination for ELM method is 0.9841, for ANN method it is 0.7956 and for the GP method it is 0.7561. Based upon simulation results, it is demonstrated that ELM can be utilized effectively in applications of GDP forecasting.

     

Wage Determination in Rural Russia: A Stochastic Frontier Model

This article examines wages in rural Russia after the first decade of economic transition using data from a nationally representative household survey. The stochastic frontier analysis reveals that Russia's rural labour markets place high value on human capital. The overall level of rural wages, however, is very low, with the median wage 10% below the official subsistence level. The gender pay gap severely depresses women's wages. A woman with the same skills as a man is paid only 47% of the man's wage. Rural workers who receive income from their personal plots accept significantly lower wages. Private firms pay considerably higher wages than state or collectively owned firms, but account only for one fifth of rural workers.     

Use of social networks in banking: a study in the Czech Republic

Social networks are becoming more and more important nowadays. Apart from regular users of the Internet, companies have started to use them in their business. Their potential is that a great number of people, future clients of big companies, use them on a daily basis. Thus, the aim of this article is to analyse the use of social networks in the banking sector of the Czech Republic, particularly with respect to customer support. The methods of this study include common data analysis and professional analysis. Common data analysis consists of the evaluation of public data from social networks and web pages of the selected bank institutions. The professional analysis is conducted by paid professional analytical tools that provide more detailed statistics. The findings of the study show that social networks are now well-established tools for the Czech banks to attract both their current and potential clients. The Czech banks seem to care about their clients by trying to meet their needs. Customer care and services provided, however, differ with type of bank.     

Counting the cost of healthy eating: a Swedish comparison of Mediterranean‐style and ordinary diets

The aim of this research was to examine the cost of a diet generally regarded as healthy, a Swedish version of the Mediterranean diet, and to compare it with the cost of an ordinary Swedish diet. A total of 30 individuals provided detailed dietary data collected in a randomized intervention study, examining the effect of dietary change to a Mediterranean‐style diet in patients with rheumatoid arthritis (Mediterranean group, n = 16, control group, n = 14). The data, covering 1‐month dietary intake, were examined with three different diet quality indicators to see whether the Mediterranean group consumed a healthier diet than the control group. All diet quality indicators showed that the Mediterranean group consumed a healthier diet than the control group. Consumer food prices were used to analyse the cost of the different diets. In immediate consumer cost terms, eating a healthier diet was more expensive when differences in energy intake were discounted. However, non‐energy adjusted costs showed no significant difference between the groups. Hence, if one of the reasons for choosing a healthier diet is to achieve weight loss – by consuming less energy – it is possible that healthier eating is not more expensive.
