Non-parametric tests of productive efficiency with errors-in-variables

We develop a non-parametric test of productive efficiency that accounts for errors-in-variables, following the approach of Varian. [1985. Nonparametric analysis of optimizing behavior with measurement error. Journal of Econometrics 30(1/2), 445–458]. The test is based on the general Pareto–Koopmans notion of efficiency, and does not require price data. Statistical inference is based on the sampling distribution of the L_∞ norm of errors. The test statistic can be computed using a simple enumeration algorithm. The finite sample properties of the test are analyzed by means of a Monte Carlo simulation using real-world data of large EU commercial banks.     

Should China Join the New Trans‐Pacific Partnership?

After President Donald Trump's ill‐advised pullout from the Trans‐Pacific Partnership (TPP) and despite the absence of the US, the remaining 11 Asian and Pacific countries agreed on a deal, renamed the Comprehensive and Progressive Agreement for Trans‐Pacific Partnership (CPTPP). The accord took effect on 30 December 2018 and provides rigorous, up‐to‐date rules for Asia‐Pacific trade, but excludes the region's two biggest economies: the US and China. In this paper, we calculate that Chinese membership in the CPTPP would yield large economic and political benefits to China and other members. The CPTPP, in its current form, would generate global income gains estimated at US$147bn annually. If China were to join, these gains would quadruple to US$632bn, or a quarter more than in the original TPP with the US. But to join the CPTPP, China would have to undertake unprecedented reforms and manage complex political challenges.     

Is more capability always beneficial for firm performance? Market orientation,core business process capabilities and business environment

This study examines the role of capabilities in core marketing-related business processes–product development management (PDM), supply chain management (SCM) and customer relationship management (CRM)–in translating a firm’s market orientation (MO) into firm performance. The study is the first to examine the interplay of all three business process capabilities simultaneously, while investigating how environmental conditions moderate their performance effects. A moderated mediation analysis of 468 product-focused firms finds that PDM and CRM process capabilities play important mediating roles, whereas SCM process capability does not mediate the relationship between MO and performance. However, the relative importance of the capabilities as mediators varies along the degree of environmental turbulence, and under certain conditions, an increase in the level of business process capability may even turn detrimental.     

Practical application of a parallel research–business innovation process to accelerate the deployment of research results

Both society and customers pose many new challenges for public research and technology organisations. Making the right long‐term technological choices, generating and maintaining an appropriate research portfolio, speeding‐up innovation processes and integrating customer and market needs into science‐based research are among the major expectations. We describe how a multidisciplinary research organisation has implemented new processes and practises to rise to these challenges. The paper points out the benefits of using a parallel research approach to the business innovation process, where the different phases – the development of new technology, applications and business models – are carried out interactively and concurrently. Furthermore, we show how foresighting acitivities, research portfolio management and use of business plans for long‐term research programmes contribute to the parallel research process.     

Green logistics in food distribution – a case study

Environmental impacts, such as Green House gas emissions, have been introduced to supply chain management as an additional parameter to traditional key performance indicators such as cost, lead-time and on-time delivery. This paper analyses a case example from the food industry on how CO₂ emissions are structured in a value chain. The focus of the analysis covers food factory order-picking operations, transportation, warehousing and distribution aspects. The paper aims to demonstrate greening and CO₂ saving potential areas of development for thermo-controlled food logistics. The results show the energy-saving potential of several supply chain processes giving examples of distribution logistic online-temperature controlling possibilities. Greening decisions in supply chain design in the food industry are considered.     

Speculative capital and currency carry trades

In this paper, we study a two-country general equilibrium model with partially segmented financial markets, where hedge funds emerge endogenously. Empirically, we show that the hedge fund investment strategy predicted by our model, which we call the “risk-adjusted carry trade” strategy, explains more than 16% of the overall hedge fund index returns and more than 33% of the fixed income arbitrage sub-index returns. The flow of new money to hedge funds affects market interest rates, exchange rates, and both the hedge funds’ contemporaneous and expected future returns as predicted by the model.     

Neglected Implications of Neoclassical Capital-Labour Substitution for Investment Theory: Another Criticism of Say's Law

Abstract

Recent mainstream macroeconomic models take Say's Law for granted. This paper argues that the justification for this assumption is not found in general equilibrium theory but in the ‘neoclassical-synthesis’ (and then monetarist) criticism of Keynes, which relies in a fundamental way on a treatment of investment that turns out to depend not only on neoclassical capital-labour substitution (called into questioned by the Cambridge controversies) but also on an assumption of full labour employment that on the contrary should be a result of the analysis. This paper first criticizes the attempt to justify a negative interest-elastic investment function through adjustment costs, that is, without relying on traditional neoclassical capital-labour substitution, with special attention on the treatment in Romer's advanced textbook. Then it proceeds to its new contribution, the demonstration that an endogenous determination of labour employment raises questions about the capacity of decreases in the real wage to raise employment even accepting neoclassical capital-labour substitution, because when the latter is correctly understood the rate of interest does not suffice to determine investment; hence, there is an inevitable role for the accelerator (and Say's Law is thereby undermined). This was perceived by Dornbusch and Fischer but they did not realize that then reductions of real wages will reduce investment instead of raising it. Thus, the ‘neoclassical synthesis’ reply to Keynes is undermined even apart from the inconsistencies of neoclassical capital theory. So the paper exposes a deficiency of the neoclassical arguments in support of a tendency toward full employment, additional to the inconsistencies revealed by the capital critique.     

Platform configurations for local and private 5G networks in complex industrial multi-stakeholder ecosystems

Data and connectivity platforms play a crucial role in the digitalization of different sectors of our society. In complex industrial multi-stakeholder ecosystem contexts connectivity and data platforms are increasingly becoming converged, and private, vertical-specific local 5G networks are emerging. For this context, we depict and analyze alternative configurations for converging connectivity and data platforms and propose appropriate management actions for combining these platforms and achieving legitimacy. We examine a complex industrial multi-stakeholder ecosystem of a port and observe that in the considered case study, the convergence of connectivity and data platforms enhances digitalization and helps to create shared local information between stakeholders. The research identifies a set of regulatory challenges for local 5G networks in complex industrial multi-stakeholder ecosystems where the telecommunication and information technology-related regulations meet with vertical-specific regulations, leading to a complex environment in which to operate. As highly country-specific, these regulations can open new business opportunities or significantly slow down or even prevent a market opening to local private 5G networks for vertical-specific use.     

Strategic marketing and business performance: A study in three European ‘engineering countries’

In spite of its relevance, the effects of strategic marketing on business performance are sparingly studied, especially in particular business contexts. We address this gap in two ways. First, we examine the influence of four key strategic marketing concepts—market orientation, innovation orientation, and two marketing capability categories (outside-in and inside-out capabilities)—on company performance. Second, these relationships are studied in three European “engineering countries:” Austria, Finland and Germany. Their relative homogeneity enables testing the generality versus context-specificity of strategic marketing's performance impact. Using SEM analysis, surprisingly weak relationships between market orientation and outside-in capabilities, and business performance are identified, as opposed to the strong role of inside-out capabilities and innovation orientation. These results can be understood through the “engineering country” characteristics. Moreover, clear differences in results are identified among these relatively homogenous countries. This is a major finding as it challenges the widely assumed generality of the strategic marketing–performance relationship. Country-specific results have also considerable managerial relevance.     

Erosion of the Ghent System and Union Membership Decline: Lessons from Finland

Union density declined in Finland by more than 10 percentage points in less than 10 years. This paper analyses the reasons behind the decline, using micro data from the 1990s. According to our results, the changes in the composition of the labour force and the changes in the labour market explain only about a quarter of this decline. The main reason for the decline appears to be the erosion of the Ghent system, due to the emergence of an independent unemployment insurance fund that provides unemployment insurance without requiring union membership. We also find that the decline in the union density can be attributed to the declining inclination of the cohorts born after the early 1960s to become union members.
