Competitive search markets for durable goods

Summary. This paper considers a dynamic version of Akerlof's (1970) lemons problem where buyers and sellers must engage in search to find a trading partner. We show that if goods are durable, the market itself may provide a natural sorting mechanism. In equilibrium, high-quality goods sell at a higher price than low-quality goods but also circulate longer. This accords with the common wisdom that sellers who want to sell fast may have to accept a lower price. We then compare the equilibrium outcomes under private information with those under complete information. Surprisingly, we find that for a large range of parameter values the quilibrium outcomes under the two information regimes coincide, despite the fact that circulation time is used to achieve separation.

Foreign Acquisitions,Domestic Multinationals,and R&D

Our aim in this paper is to evaluate the causal effect of foreign acquisition on research and development (R&D) intensity in targeted domestic firms. We are able to distinguish domestic multinational enterprises (MNEs) and non‐MNEs, which allows us to investigate the fear that the change in ownership of domestic MNEs to foreign MNEs leads to a reduction in R&D activity in the country. Overall, our results give no support to the fears that foreign acquisition of domestic firms leads to a relocation of R&D activity in Swedish MNEs. Rather, in this paper, we find robust evidence that foreign acquisitions lead to increasing R&D intensity in acquired domestic MNEs and non‐MNEs.     

Determinants of patent value: Insights from a simulation analysis

This paper contributes to understanding the determinants of patent value. By drawing on a real options approach, we develop a theoretical model of patent value, which explicitly considers the uncertainty about future value. On this basis, we rely on Monte Carlo simulations with data from a case study in a large chemical firm to estimate patent value according to our model. In the simulation analyses, we compare an R&D project with patent protection and the same project without patent protection. The difference of the values of the two projects is the surplus in profit that may be expected from having a patent covering the project. This surplus is regarded as the value that is directly attributable to the patent. The results of the simulation analyses indicate that the development costs and expected net cash flows of a patent-protected project are higher than of an unpatented project. The higher net cash flows outgrow the increased development costs, and patent value is positive. However, this value is smaller than the overall project value of the patent-protected R&D project.     

Testing the parametric form of the volatility in continuous time diffusion models—a stochastic process approach

We present new tests for the form of the volatility function which are based on stochastic processes of the integrated volatility. We prove weak convergence of these processes to centered processes whose conditional distributions are Gaussian. In the case of testing for a constant volatility the limiting process are standard Brownian bridges. As a consequence an asymptotic distribution free test and bootstrap tests (for testing of a general parametric form) can easily be implemented. It is demonstrated that the new tests are more than the currently available procedures. The new approach is also demonstrated by means of a simulation study.     

Winners and losers: a micro-level analysis of international outsourcing and wages

Abstract.  Our paper investigates the link between international outsourcing and wages utilizing a large household panel and combining it with industry-level information on industries' outsourcing activities from input-output tables. This approach avoids problems such as aggregation bias, potential endogeneity bias, and poor skill definitions that commonly hamper industry-level studies. We find that outsourcing has had a marked impact on wages. Applying two alternative skill classifications, we find evidence that a 1 percentage point increase in outsourcing reduced the wage for workers in the lowest skill categories by up to 1.5%, while it increased wages for high-skilled workers by up to 2.6%. This result is robust to a number of different specifications.     

Resource utilization and procedure-related costs associated with transfemoral transcatheter aortic valve replacement

Aims: Transcatheter aortic valve implantation (TAVI) is an alternative to surgical valve replacement for patients with aortic stenosis (AS). This study assessed the impact of changing from a self-expandable (SE) valve to a balloon-expandable (BE) valve on healthcare resource use and procedural costs in a population of inoperable AS patients.

Methods: In this retrospective single center study, data for 195 patients who received either an SE or a BE valve between 2010–2014 were collected. Procedural and post-procedural healthcare resource use and cost parameters were determined for the two groups.

Results: The study showed that overall procedural time, including time required by medical personnel, was significantly shorter for TAVI using a BE compared with an SE valve. Post-surgery, patients in the BE valve group had significantly shorter hospital stays than the SE valve group, including significantly fewer days spent in the intensive care unit (ICU). Additionally, trends towards reduced 30-day mortality, incidence of new permanent pacemaker implantation, and incidence of blood transfusion were observed in the BE valve group compared with the SE valve group. Finally, total procedural costs were 24% higher in the SE compared with the BE valve group.

Limitations: The BE valve data were acquired in a single year, whereas the SE valve data were from a 5-year period. However, a year-by-year analysis of patient characteristics and study outcomes for the SE valve group showed few significant differences over this 5-year period.

Conclusions: Overall, changing from an SE to a BE valve for TAVI in patients with severe AS reduced both healthcare resource use and procedure-related costs, while maintaining patient safety. For healthcare providers, this could increase efficiency and capacity within the healthcare system, with the added advantage of reducing costs.     

Outsourcing,Importing and Innovation: Evidence from Firm‐level Data for Emerging Economies

This paper investigates two sourcing strategies of firms, outsourcing and importing, and links these to innovation activities. The authors examine this empirically using firm‐level data for 28 emerging market economies and find robust evidence that outsourcing increases the likelihood to spend on R&D and via this channel raises innovation output, whereas importing increases innovation output, but not R&D. The results hold when implementing an instrumental variables approach. It is found that results crucially depend on the institutional environment in the economy, e.g. property rights and intellectual property rights protection. The results suggest that better institutions magnify the gains from importing, but not from outsourcing. EU countries also reap additional positive innovation effects from importing compared with non‐EU countries.     

When is Effort Contagious in New Venture Management Teams? Understanding the Contingencies of Social Motivation Theory

Consistent with social motivation theory, prior research on managerial motivation suggests that effort is contagious across management team members. In this study, we draw on belongingness theory to develop a model on important boundary conditions to social motivation theory in the management team context. The model predicts that new venture managers react to their teammates’ higher effort levels by investing higher effort levels themselves primarily when they are confronted with a threat – namely, low venture performance and high environmental hostility – but that effort is less contagious when managers face little threat. We test our model with a sample of 103 new venture managers nested in 51 management teams in a longitudinal setting capturing managerial effort over 26 weeks. While we do not find a direct relationship between teammates’ effort and a new venture manager’s subsequent effort, we find support for the crucial role of threat in triggering the contagion of managerial effort. We discuss the contributions of our study for research on management teams, performance feedback, and entrepreneurial effort in new ventures.     

Customer relationship management and company performance—the mediating role of new product performance

Customer Relationship Management (CRM) is widely accepted as an effective approach for collecting, analyzing, and translating valuable customer information into managerial action. However, the potential of CRM has been investigated only in the context of existing products. CRM’s potential to aid in future new product development (NPD) has been neglected. We develop a conceptual framework in which multiple facets of CRM are linked to new product and company performance. We test this model based on a cross-functional sample consisting of 115 R&D and 122 Marketing managers from firms spanning multiple industries. The results provide evidence that CRM has a positive effect on new product performance and further, that this effect is moderated by CRM reward systems but not CRM technology. We also show that new product performance mediates the relationship between CRM and company performance. These findings have important implications for research and practice in both the CRM and NPD areas.     

Beyond the Toledo agreement: the intergenerational impact of the Spanish Pension Reform

The paper examines the intergenerational impact of the Spanish public pension system after the 1997 Pension Reform Act. Within a Generational Accounting framework, we find that the new legal setting could leave future generations with liabilities as high as 176% of 1996 GDP. Hence, we analyse the impact of alternative reforms. Holding the pay-as-you-go setting, a further improvement to tax-benefit linkage in line with the Toledo Agreement proposals is shown to yield an intergenerationally more balanced outcome, than an increase in the retirement age or an expansion of public subsidies financed through indirect taxes. Finally, a move toward a partially funded pension system which restores the intergenerational balance is simulated.
