This paper presents a statistical framework for estimating output-specific efficiencies for the 2-output case based upon a DEA frontier estimate. The key to the approach is the concept of target output-mix. Being usually unobserved, target output-mixes of firms are modelled as missing data....

This paper provides simulation evidence concerning some statistical properties of two different approaches to technical efficiency estimation for multiple-output production under noisy conditions: The Ray Frontier Approach (RFA) from Löthgren (1997) DEA+ proposed in Gstach (1996). RFA, unlike...

The outcome of a production process might not only deviate from a theoretical maximum due to inefficiency, but also because of non-controllable influences. This raises the issue of reliability of Data Envelopment Analysis in noisy environments. I propose to assume an i.i.d. data generating...

This paper deals with income redistribution and fiscal effects caused by immigration in a two-sector economy ith fixed capital endowments. We consider immigration under political control into one sector only, guided by the stylized fact that empirical immigration distributions often appear...

A dynamic IS-LM model including stocks and houses as additional assets will be analyzed in this paper. Providing also housing services, a major consumption item for most households, houses create an additional link between the monetary and the real sector of the economy. The adjustment path of...

This paper surveys four distinct approaches to frontier estimation of multi-output (and simultaneously multi-input) technologies, when nothing but noisy quantity data are available. Parametrized distributions for inefficiency and noise are necessary for identification of inefficiency, when only...

Using income and other individual data from EU-SILC for Germany and Austria, we analyze wage discrimination for three break-ups: gender, sector of employment, and country of origin. Using the method of Machado and Mata [2005] the discrimination over the whole range of the wage distribution is...

Modern macroeconomic models with a Keynesian flavour usually involve nominal rigidities in wages and commodity prices. A widely used conceptual framework is specifying a wage-setting and a price setting equation, while a more explicit microfoundation recurs to wage bargaining in the labour...

In this paper I analyze a vertically structured monopolized market with unionized firms. I compare two types of contracts: vertical integration and franchising. With franchising and wage bargaining at the firm level the union in the downstream firm is either very powerful or has no bargaining...
