A general method for testing the martingale difference hypothesis is proposed. The new tests are data-driven smooth tests based on the principal components of certain marked empirical processes that are asymptotically distribution-free, with critical values that are already tabulated. The...

The minimization of general risk or dispersion measures is becoming more and more important in Portfolio Choice Theory. There are two major reasons. Firstly, the lack of symmetry in the returns of many assets provokes that the classical optimization of the standard deviation may lead to...

A new insurance provider or a regulatory agency may be interested in determining a risk measure consistent with observed market prices of a collection of risks. Using a relationship between distorted coherent risk measures and spectral risk measures, we provide a method for reconstruction...

This paper contributes to the permanent income hypothesis (PIH) and excess consumption smoothness debate in the context of fractional integration. We show that the excess consumption smoothness result is a consequence of the quarterly data frequency commonly employed in empirical work. In fact,...

Operations managers are becoming more important in modern corporations. They do not only care on firms’ inventory management but also they are involved in firms’ strategic decisions. Within this setting we ask about the consequences in the inventory policy of this new role undertaken by...

This paper offers a framework within which the corporate’ corruption may be analyzed and a comprehensive road map to understand the role played by corporation on corruption. Despite corruption is a field with a long tradition and a common topic of many researches, disagreements persist about...

We formulate and solve a Rational Expectations New Keynesian macro model that implies non-linear cross-equation restrictions on the dynamics of inflation, the output gap and the Federal funds rate. Our maximum likelihood estimation procedure fully imposes these restrictions and yields asymptotic...

Despite the growing role that business has played in the development of capitalism, the neo-classical paradigm has largely ignored the concept of organization. This paper illustrates the neo-classical concept of the firm and the entrepreneur. Analyzing both, the moral and economic thought of...

Journal rankings based on citation indexes are widely used in the economics field for global top journals. We propose an alternative way to rank journals based on the publishing behavior of top ranked authors. We justify this approach by depicting the scientific publishing market as following a...
