Gender-specific differences in labor market adjustment patterns: Evidence from the United States

Do men and women behave differently while adjusting labor supply over the business cycle? Using data from the United States, we show that women are significantly more likely to adjust along the intensive margin (number of hours), while men adjust more along the extensive margin (employment). Older, single, and divorced/widowed adjust predominantly along the extensive margin.     

The role of deliberate and experiential learning in developing capabilities: Insights from technology licensing

We discuss the interdependencies between deliberate and experiential learning in developing a dynamic technology licensing capability, which was termed ‘desorptive capacity’ in earlier conceptual work. We use new three-year lagged data from two surveys of 79 firms to examine the role of dedicated licensing employees and prior licensing experience in developing firms’ sensing, seizing, and transforming capacities in technology out-licensing. The findings emphasize capabilities’ multidimensionality and critical trade-offs due to interdependencies between deliberate and experiential learning in developing capabilities. Besides interdependencies with experiential learning, deliberate learning strengthens sensing and seizing capacity, but it negatively affects transforming capacity based on inertia.     

A review of RFID technology and its managerial applications in different industries

Radio frequency identification (RFID) is an emerging technology that is increasingly being used in supply chain management. RFID technology plays an important role in supporting logistics and supply chain processes because of their ability to identify, trace and track information throughout the supply chain. The technology can provide suppliers, manufacturers, distributors and retailers precise real time information about the products. This accurate knowledge of the inventory would result in lower labor cost, simplified business processes and improved supply chain efficiency. If properly used, it has the potential to cut ordering lead time and cost on inventory control, increase the accuracy of inventory information, help avoid stockouts and boost the number of inventory turns. In this paper, we provide an overview of the current state of RFID applications in different industries and its impact on business operations. We provide extensive literature survey and develop a framework for future research areas in this field.     

The Access of the Young Graduates in Sciences into R&D Profession: A Switching Model Treatment for the French Case

We address the question concerning the choice of graduates in sciences and engineering to look for employment in research and development. We use an endogenous switching regression to avoid the existence of self‐selection biases. The study shows that human capital is decisive where both employment opportunities and remuneration are concerned within, but not without, this sector. The results also suggest that in the early stages of a career, the R&D sector is less rewarding than other types of employment only for doctors and not for graduates from engineering schools.     

OIL AND THE MACROECONOMY: A QUANTITATIVE STRUCTURAL ANALYSIS

We model an open economy where macroeconomic variables fluctuate in response to oil supply shocks, as well as aggregate demand and supply shocks generated domestically and abroad. We use several robust predictions of the model to identify five fundamental shocks underlying the fluctuations of the (real) oil price, the US activity and the global business cycle. The estimates show that supply shocks generated in the global economy explain the largest fraction of the oil price fluctuations, about four times more than canonical oil supply shocks. The correlation between oil prices and the US activity varies with the type of shock.     

Altruism and the macroeconomic effects of demographic changes

In this paper we show that the macroeconomic effects of demographic changes strongly depend on the degree of altruism and on the specification of the intertemporal utility function. We allow for agents either to be altruistic in the sense of Barro (1974) or non-altruistic. In the latter case, generations are heterogeneous like in the „unloved children” model of Weil (1989). In the former case, where the model is a standard Ramsey model with identical agents, we distinguish a Millian and a Benthamite intertemporal utility function. For each of these models, we study the effects of an anticipated and unanticipated permanent decline in population growth as well as the consequences of a baby-boom/baby-bust scenario.

Critical success factors in managing modular production design: Six company case studies in Hong Kong, China, and Singapore

Many researchers have explored the advantages of modular product design, its design methods and its effects on product performance. Modular design is, for example, required for product platform, mass customization and postponement in order to achieve greater product variety and differentiation. However, a few empirical studies explicitly examine how to coordinate modular product design in a managerial way. This paper addresses it by conducting multiple case studies with six companies which have successfully adopted modular product design for five years. Seven critical factors are explored in the management of modular product design. These are pre-defined product advantage, selectively used design rules, module definition, system integration, technological newness, internal communication, and supplier and customer involvement. While most of the literature studies the technical dimension of modular design within a firm, this study focuses on the managerial side across the supply chain. It gives new insights on how to manage modular product design and proposes future research opportunities.     

An assessment framework based on social perspectives and Analytic Hierarchy Process: A case study on sustainability in the Japanese concrete industry

This research introduces a framework for assessing concrete sustainability which is based upon the concept that technology is defined by stakeholders’ perspectives and which applied Analytic Hierarchy Process to translate these perspectives into quantifiable assessment values. A survey was conducted to identify important criteria, and several “design scenarios” were introduced which represent different value systems by varying criteria importance. Concrete materials with varying environmental impact were then assessed to observe the effect of different value systems and material properties, and it was found that the concrete with better properties was generally selected as most sustainable regardless of the design scenario.     

LABOR‐MARKET HETEROGENEITY,AGGREGATION, AND POLICY (IN)VARIANCE OF DSGE MODEL PARAMETERS

Data from a heterogeneous‐agents economy with incomplete asset markets and indivisible labor supply are simulated under various fiscal policy regimes and an approximating representative‐agent model is estimated. Preference and technology parameter estimates of the representative‐agent model are not invariant to policy changes and the bias in the representative‐agent model’s policy predictions is large compared to predictive intervals that reflect parameter uncertainty. Since it is not always feasible to account for heterogeneity explicitly, it is important to recognize the possibility that the parameters of a highly aggregated model may not be invariant with respect to policy changes.
