Does Shelf-Labeling of Organic Foods Increase Sales? Results from a Natural Experiment

Can a simple point-of-purchase (POP) shelf-label increase sales of organic foods? We use a random-effects, random-coefficients model, including a time adjustment variable, to test data from a natural experiment in a hypermarket in Gävle, Sweden. Our model incorporates both product specific heterogeneity in the effects of labeling and consumer adjustment to the labels over time. The introduction of POP displays was found to lead to an increase in sales of organic coffee and olive oil, but a reduction in sales of organic flour. All targeted products became less price-sensitive. The results reveal that product specific heterogeneity has to be accounted for, and in some cases consumers adjusted to labeling over time.Product labeling; random coefficient models; ecological products; experimental economics

When is Gibrat's Law a Law?

The purpose of this paper is to investigate if the industry context matters for whether Gibrat's law is rejected or not using a dataset that consists of all limited firms in 5-digit NACE-industries in Sweden during 1998-2004. The results reject Gibrat's law on an aggregate level, since small firms grow faster than large firms. However, Gibrat's law is confirmed about as often as it is rejected when industry-specific regressions are estimated. It is also found that the industry context - e.g., minimum efficient scale, market concentration rate, and number of young firms in the industry - matters for whether Gibrat's law is rejected or not.Firm growth; firm size; job creation; small firms

Central Bank Independence and Price Stability: Evidence from 23 OECD-countries

In this paper, we use a non-parametric regression method to compare the transition process from high to low inflation with the implementation dates of central bank independence reforms. In a majority of the countries, price stability is achieved before more independence is given to the central bank. This suggests that the credibility of a low inflation goal can be achieved without institutional reforms which grant the central bank more independence from the political policymakers.Central bank reform; inflation targeting; monetary policy; non-parametric decomposition

Why Do Politicians Implement Central Bank Independence Reforms?

It is something of a puzzle that politicians around the world have chosen to give up power to independent central banks, thereby reducing their possibilities to fine-tune the economy. In this paper the determinants of central bank independence (CBI) reforms are studied using a new data set on the possible event of such reforms in 119 countries. According to the data, as much as 81 countries had implemented CBI-reforms during the study period. The results indicate, moreover, that policymakers are more likely to delegate power to independent central banks when the foreign debt is relatively high. In non-OECD countries, the likelihood of a CBI-reform also seems to increase when policymakers face a high probability of getting replaced.Institutional reforms; inflation; time-inconsistency; political stability; probit

Consumption and income inequality in Sweden: a different story

This paper analyzes consumption- and income inequality trends in Sweden during the period 1988-2005. Similar studies for the US have found that consumption inequality has increased much less than income inequality in recent decades. Results in this paper indicate that consumption inequality actually decreased in Sweden in spite of considerable overall increase in income inequality. The apparent contradiction can mainly be explained by increased saving and life cycle redistribution among high-income households.Income distribution; earnings; consumption; equality

Entry into Swedish Retail- and Wholesale Trade Markets

In this paper, a Poisson regression model is used to study the determinants of entry of new firms into the Swedish retail- and wholesale trade markets. The results suggest that incumbent firms engage in strategic behavior to prevent the entry of newcomers. Regional factors are also found to be important determinants of entry.Wholesale trade; retail trade; entry; number of firms; panel data

The economic contribution of high-growth firms: Do definitions matter?

Prior studies have defined high-growth firms (HGFs) in terms of sales or employment, and analyzed their contribution to employment growth. We define HGFs by employment and sales and add definitions of value added and productivity. We examine the contribution of HGFs to employment growth, economic growth, productivity growth, and sales growth. All HGFs give a disproportionately large positive contribution to economic growth and most also give large positive contributions to growth in employment, productivity and sales. Although HGFs of different definitions are usually not the same firms, young firms are more likely to be HGFs irrespective of definition.Gazelles; Firm growth; High-impact firms
