Adjustment to changing international conditions

The structural changes in the world economy have made themselves increasingly felt in the Federal Republic of Germany over the past few years. For the first time since 1965 there is again a current account deficit, since merchandise trade is no longer able, due to the worsened terms of trade, to finance the traditional deficits on services and transfers. What policy should the Federal Government follow in order to help German industry adjust to these changes?     

Friend or Foe?— Farmer Perceptions of Biotechnologh1

This paper is the result of survey investigation the attitudes of Western Canadian farmers toward two biotechonological products, ENFIX-L and PB-50. Farmers were asked to rate both the importance and the performance of 21 attributes of the products. Soil depletion was found to be an important concern to many farmers. personal and environmental risks were less of a concern. Overall, it was found that the non-biotech-nological aspects of a product would prevail in purchasing decisions.     

Exchange‐Sponsored Analyst Coverage

Several major stock exchanges, including the NASDAQ and NYSE Euronext, have recently embarked on schemes to sponsor and promote analyst coverage for firms listed on their exchanges. We evaluate the efficacy of one such scheme pioneered by the Singapore Exchange (SGX). We find that sponsored analysts produce forecasts with similar bias, but lower accuracy than those issued by analysts voluntarily following a firm. In analyses that control for self‐selection into the SGX Scheme, we find that sponsored firms enjoy at best minor improvements in their information environments and stock liquidity. Any benefits accruing from the scheme are insufficient to make sponsored firms fully comparable to those of firms with voluntary analyst following on the measured attributes.     

Assessing Productivity Gains from International Trade in a Small Open Economy

Empirical evidence suggests that exporter firms tend to charge higher markups than non-exporters due to trade barriers. The exporters’ markup premium, however, may disappear in a special case, namely when the home country is small relative to its trade partners and trade barriers are low. This can be because competition is more intense in the large export destination than in the small home country, so that firms are able to set higher markups for locally sold products but not for exports. This paper provides empirical evidence on the validity of this special case by estimating markups for firms in Luxembourg who generally export to larger countries. The estimated negative markup premium for exporters has important implications for the productivity measurement. In a sufficiently small open economy, exporters’ productivity may be biased downward, when the firm-level markup variation is not controlled for in the productivity estimation. The bias in the productivity estimates further leads to the inaccurate conclusion that openness to international trade lowers allocative efficiency.     

On Measurement of Economic Growth

This article continues the discussion raised in the pages of the journal on the methodological problems of justifying economic policy [1]. Problems of measuring the inflationary component of economic growth and in product competitiveness in the internal market and external markets are considered. A procedure to measure economic growth, taking into account the balance of interests of the current and future generations, is proposed.     

Tax system and informal economy: a cross-country analysis

This article analyses determinants of informal economy. By using qualitative aspects of tax systems, first, we create a ‘Smithian’ tax system index based on Adam Smith’s four maxims. Then, using this index and other control variables, we study determinants of informal economy. We use unique panel data set that is constructed by using various sources. After taking into account the endogeneity of tax burden and GDP per capita, our results show that ‘Smithian’ tax system index does not significantly affect informal economy. Our results suggest that rule of law, complexity of a tax system and tax burden affect informal economy negatively, while labour market regulations affect positively.     

Politically stable pay-as-you-go pension systems: When the social-insurance budget is too small in a democracy

The essay analyzes in an overlapping-generations model, to which extent a pay-as-you-go pension system will be the outcome of majority voting, given specific institutional set-ups. Clearly, the vote of an active person depends on his expectations about how the present decision (i.e., his contribution) is linked to the future (i.e., his benefits), when he will be retired. In the paper we employ the assumption of a basic social contract where each active voter's future benefits are positively related to his contributions. It is shown that in this framework a steady-state with a positive (though lower than optimal) level of the pension system exists, even if a new majority decision about the system takes place every period.
