A Conic Algorithm for the Group Minimization Problem
Simeone, Bruno - 1976
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 …

Does Offshoring Production Reduce Innovation : Firm-Level Evidence from Taiwan
Branstetter, Lee; Chen, Jong-rong; Glennon, Britta; … - National Bureau of Economic Research - 2021
Does the offshoring of production degrade or enhance the innovative capabilities of manufacturing firms? We contribute to this debate by exploiting a policy shock that differentially affected the ability of Taiwanese firms to offshore some products to China. We find causal evidence that...

Monopoly and the Incentive to Innovate When Adoption Involves Switchover Disruptions
Holmes, Thomas J. - 2008
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...

Complementarities in Automobile Production
Van Biesebroeck, Johannes - 2006
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...

Missing Gains from Trade?
Melitz, Marc J. - 2014
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...

Supply-Chain Trade : A Portrait of Global Patterns and Several Testable Hypotheses
Baldwin, Richard - 2013
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...

How Firms Export : Processing vs. Ordinary Trade with Financial Frictions
Manova, Kalina - 2012
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 -...

Organizational Responses to Product Cycles
Adhvaryu, Achyuta; Bassi, Vittorio; Nyshadham, Anant; … - National Bureau of Economic Research - 2023
We use daily administrative data from a leading automobile manufacturer to study the organizational impacts of introducing new models to the auto assembly line. We first show that costly defects per vehicle spike when new models are introduced. As a response, the firm trains in problem-solving...

An Adaptive Nonlinear Least Square Algorithm
Dennis, John E. - 1977
NL2SOL is a modular program for solving the nonlinear least-squares problem that incorporates a number of novel features. It maintains a secant approximation S to the second-order part of the least-squares Hessian and adaptively decides when to use this approximation. We have found it very...
