Mobile technology usage and B2B market performance under mandatory adoption

This paper investigates the relationship between mandatory adoption of mobile information technology and market performance in the business-to-business (B2B) setting. This study presents and tests the B2B technology satisfaction model (TSM), including perceived loss of control as the mandatory technology acceptance-specific variable. The results of this study reveal that integrating perceived loss of control with user satisfaction and the TAM (technology acceptance model) in a single model can better explain the B2B market performance model. The empirical results suggest that perceived loss of control has a negative effect on user satisfaction and perceived market performance is influenced by user satisfaction and perceived usefulness. Managerial implications of the study are discussed.

Modes of cooperative R&D commercialization by start‐ups

This study empirically examines the determinants of heterogeneous firm‐level cooperative R&D commercialization strategies. While the volume of interfirm collaboration has increased dramatically in recent decades, the determinants of firm‐level choices among alternate modes of such cooperative activity remain relatively understudied. We develop a conceptual model of factors determining collaborative mode choice at the organizational portfolio level. These factors include the firm‐level appropriation environment, in which deal‐level choices have portfolio‐level spillover implications, as well as governance capabilities developed by the firm over time. Using a random sample of innovating biotechnology start‐ups, we assemble a firm‐year panel dataset that aggregates transaction‐level collaboration data to the firm‐year level, allowing us to characterize firms' portfolios of collaborative deals. We find broad empirical support for our model, suggesting that a firm's appropriation environment and governance capabilities strongly influence portfolio‐level collaboration mode choices. In addition, we explore the implications of governance capability development, finding that experience with particular modes, as well as deviations from existing capabilities, impact firm valuation.

Multinational firms, exclusivity, and backward linkages

How does the nature of contractual relationships between a multinational and its local suppliers affect backward linkages and welfare in the local industry? We address this question in a two-tier oligopoly model where a multinational transfers technology to its suppliers if they accept an exclusive contract that precludes them from serving its local rivals. Invited suppliers balance the benefits of gaining access to new technology and the derived demand of the multinational against the opportunity of selling to other local firms. Exclusivity reduces competition among local suppliers and can lower backward linkages and local welfare relative to autarky.     

The allocative efficiency and conservation potential of water laws encouraging investments in on-farm irrigation technology

Agricultural water conservation statutes are emerging in the West encouraging private irrigators to improve on‐farm irrigation efficiency as a basinwide conservation measure. We investigate whether private improvements promote the economic efficiency and conservation of water use basinwide under a wide variety of hydroeconomic circumstances. The standard of efficiency is how an irrigation district manager should optimally invest in improving the irrigation efficiencies of individual farms located along a stream while internalizing intrabasin allocative externalities of these investments. The results indicate that the popular Oregon legislative model may be the least effective in conserving water and promoting economically efficient water allocation.

Process System Modelling of Production Technology Alternatives using Input– Output Tables with Sector Specific Units

Input–output analysis is usually based on tables of accounts expressed in uniform monetary or physical units. However, from a process system modelling perspective, tables of accounts in sector specific units may be more useful for evaluating the effectiveness of new production technologies on reducing pollutant emissions. Using the sector specific unit conceptualization of an IO table, one can consider the effect of changes in direct input coefficients for a particular sector on the complete set of total input coefficients independently from the other direct input coefficients. A process system modelling based method for calculating the total industrial outputs from a new technology matrix together with the new relative prices for each sector output is presented. The method is then used to study the effect of technology changes in the steel making industry in Liaoning Province, China on prices and pollutant emissions.     

The Role of Monetary Policy in the New Keynesian Model: Evidence from Vietnam

This paper re-designs the New Keynesian model developed by Ireland (2004 Ireland, P. N. (2004). Technology shocks in the New Keynesian model. The Review of Economics and Statistics, 86(4), 923–936. doi: 10.1162/0034653043125158[Crossref], [Web of Science ®] , [Google Scholar]) and then uses the Vietnamese data from January 1995 to December 2012 to estimate the model's parameters. The empirical results show that the State Bank of Vietnam had been more aggressive as well as more responsive to aggregate fluctuations in the period before August 2000 than in the latter period. Thus, this change in the policy stance could be a potential reason for the declining importance of monetary policy in generating movements in output growth, inflation, interest rate, and the output gap across the subsamples. Another notable finding is the dominant role of the cost-push shock in explaining fluctuations in inflation, interest rate, and the output gap, leading to a policy implication that more attention should be devoted to developing substitute and complement industries so as to mitigate negative effects of the cost-push shocks by reducing the degree of dependence on imports.
