This paper focuses on a systematic quantitative discussion of the shortand long-term impact of remarkable economic events on international trade in a two-stage framework. Firstly, procedures based on dummy variables are proposed to detect structural breaks, types and sizes of jumps caused by such events. Then we propose to apply a hierarchical CMS (Constant Market Share) model to all sub-period...

Physical therapists are trained in manual examination techniques to test the impaired motor functions of patients. In this study, we have introduced a wearable robotic dummy joint to simulate disordered joint resistances or behaviors to support physical therapists in learning such techniques. We developed a discontinuous joint friction model based on a stick-slip phenomenon to simulate knee joi...

Does growth management result in lower marginal land consumption rates? The literature offers inconclusive and inconsistent results. This paper uses new data covering all U.S. metropolitan areas and multiple time periods to estimate panel models of effects of growth management on the spatial extent of urban development. Dummy variable estimation misleadingly suggests that growth management incr...

This note presents the Seabreath wave energy converter, basically a multi-chamber floating oscillating water column device, and the lumped model used to size its chambers, the ducts and the turbine. The model is based on extensive testing carried out in the wave flume of the University of Padova using fixed and floating models with a dummy power take off and indirect measurement of the produced...

A multiple regression analysis of growth in juvenile tilapia Oreochromis niloticus and 0. aureus (Cichlidac) is presented based on experiments conducted from 1984 to 1987 in recirculating systems a t the Tilapia Genetics Laboratory of the University College of Swansea. Wales, UK. One regression model was derived for 0. niloticus, one for 0. aureua and one for both species jointly. Overall fit, ...

Economic activities, both on the macro and micro level, often entail wide-spread externalities. This in turn leads to disputes regarding the compensation levels to the various parties affected. We propose a method of deciding upon the distribution of the gains (costs) of cooperation in the presence of externalities when forming the grand coalition is efficient. We show that any sharing rule sat...

In two-person generosity games the proposer's agreement payo is exogenously given whereas that of the responder is endogenously determined by the proposer's choice of the pie size. Earlier results for two-person generosity games show that participants seem to care more for e ciency than for equity. In three-person generosity games equal agreement payo s for two of the players are either exogeno...

The paper extends existing work on inequality and economic development by estimating a cross-country structural model that identifies bi-directional relationships between income inequality and other indicators of social and economic development. Overall, lower inequality is associated with improvements in other development indicators, but this is the result of several complex interactions. The ...

The sign-propagation algorithm for inference with a qualitative probabilistic network has been designed to handle a single observation at a time. Multiple observations can in essence be dealt with by entering them consecutively and combining the results of the successive propagations, or by entering them for a newly added dummy node. We demonstrate that both approaches can yield weaker results ...

In 2003 the endless list of LATEX packages was enriched by the package pict2e, intended to substitute for the dummy one that has accompanied every LATEX distribution since 1994. This package implements everything as stated by Lamport in the second edition of his LATEX manual (for LATEX2ε). But if you explore the inner workings of the new pict2e, you discover the new package has some unexpected ...
