In this paper, we consider testing marginal normal distributional assumptions. More precisely, we propose tests based on moment conditions implied by normality. These moment conditions are known as the Stein (1972) equations. They coincide with the first class of moment conditions derived by...

This paper illustrates the usefulness of resampling based methods in the context of multiple (simultaneous) tests, with emphasis on econometric applications. Economic theory often suggests joint (or simultaneous) hypotheses on econometric models; consequently, the problem of evaluating joint...

A wide range of tests for heteroskedasticity have been proposed in the econometric and statistics literatures. Although a few exact homoskedasticity tests are available, the commonly employed procedures are quite generally based on asymptotic approximations which may not provide good size...

This paper provides evidence based on French macroeconomic data, that shocks on the cost of oil inputs are transmitted asymmetrically to the prices of fuel. We use an error correction model to estimate the dynamics of the transmission of the cost of crude oil expressed in French currency, to the...

This article analyzes the profitability of the banks in six European countries between 1994 and 1997. We deal with the link between profitability and certain external and interns' determinants of European banking system. Following a methodology of panel analysis with a fixed individual effects...

By starting with the statement of Alfred Marshall: "The most valuable of all capital is invested in being human" we can consider the quality of human resources in general and quality of educational resources, especially as a decisive factor for economic growth together. The specialists...

During the marginalist controversy, full costers failed to convince economists of the superiority of full cost pricing over marginal theory of imperfect competition. The controversy was closed prematurely; various contributions published immediately thereafter in the fifties did not renew the...

Since the marginalist controversy held from 1939 to the mid-fifties, the full cost principle presents itself as an alternative to the marginalist theory of the producer’s equilibrium, without being able to shake its dominance. Yet, through decades, empirical investigations are rather...

We analyze whether and how the fact that products are not sold on free, public, platforms but on competing for-profit platforms affects sellers’ investment incentives. Investments in cost reduction, quality, or marketing measures are here to joint and coordinated efforts by sellers. We show...

This paper documents producer price setting in 6 countries of the euro area: Germany, France, Italy, Spain, Belgium and Portugal. It collects evidence from available studies on each of those countries and also provides new evidence. These studies use monthly producer price data. The following...
