A new algorithm for the group minimization problem (GP) is proposed. The algorithm can be broadly described as follows …-known algorithm of Glover, and checked for non-negativity. The first non-negative point is an optimal solution of (GP). Advantages and … disadvantages of the algorithm are discussed; in particular, the implementation of the algorithm (which can be easily extended so as …

The trade linked to international production networks - supply-chain trade for short - is associated with momentous global economic changes. This paper presents a portrait of the global pattern of supply-chain trade and how it has evolved since 1995. The paper draws on a variety of data sources...

The fragmentation of production across borders allows firms to make and export final goods, or to perform only intermediate stages of production by processing imported inputs for re-exporting. We examine how financial frictions affect companies' choice between processing and ordinary trade –...

The number of different car and light truck models produced in North America has increased enormously over the last decades. The data suggests that producing this increased variety of vehicles is associated with a productivity penalty. We show that manufacturers can adopt complementary...

The theoretical result that there are welfare gains from trade is a central tenet of international economics. In a class of trade models that satisfy a "gravity equation," the welfare gains from trade can be computed using only the open economy domestic trade share and the elasticity of trade...

When considering the incentive of a monopolist to adopt an innovation, the textbook model assumes that it can instantaneously and seamlessly introduce the new technology. In fact, firms often face major problems in integrating new technologies. In some cases, firms have to (temporarily) produce...

In addition, by focusing the algorithm on predicting judges' decisions, rather than defendant behavior, we gain some …

The law forbids discrimination. But the ambiguity of human decision-making often makes it extraordinarily hard for the legal system to know whether anyone has actually discriminated. To understand how algorithms affect discrimination, we must therefore also understand how they affect the problem...
