Portfolio flows and the US dollar–yen exchange rate

This paper investigates the effects of portfolio flows on the US dollar–Japanese yen exchange rate changes over the period 1988:01–2011:04. Using a time-varying transition probability Markov-switching framework, the results suggest that the impact of portfolio flows on the dollar–yen exchange rate changes is state-dependent. In particular, the results show that portfolio inflows from Japan toward the US, more than monetary variables, strengthen the probability of remaining in the dollar–yen appreciation (low volatility) state. Therefore, credit controls on the flows can be used as a policy tool to pursue economic and financial stability.     

ON TECHNOLOGY COMPETITION: A FORMAL ANALYSIS OF THE ‘SAILING-SHIP EFFECT’

One of the key features of our economies consists of the coexistence of different technologies supplying similar products and services. We often observe that an old technology is improved when a new one appears; behind this process of improvement often lies an intentional research activity. There thus begins a competition between the two technologies whose performances are improved via R&D. We focus our attention on this competition process and supply a formal model, based on the optimization of R&D expenditure of both technologies, which can describe the dynamics of the delayed overtaking of the new technology over the old one.     

Evaluation of the opportunity cost of the spectrum: Application to the digital dividend

The transition to digital television transmission (DTT) creates an opportunity for revising the current allocation and use of the spectrum, and for enhancing its efficiency. The fairly large amount of spectrum that will be freed up in the analog TV switch-off is known as the digital dividend. Many EU countries have decided to partially allocate these frequencies, through market mechanisms, to mobile use, but a large fraction of the dividend is supposed to remain in the hands of broadcasters. An efficient management of the spectrum requires that the use of this resource should be supported through appropriate incentive policies. This paper presents a techno-analytical approach to evaluate the opportunity cost of using a spectrum portion within the digital dividends’ bandwidths, for example around 800-900 MHz, for both DVB-T and UMTS services, specifically addressing the extraordinary rise in the use of mobile broadband in the European context. The methodology is then applied to Italy to derive a baseline for administered prices reflecting the cost of spectrum use. Results obtained are then compared with existing evidences from other studies and Countries’ experiences.     

Consumer Ethics in the European Union: A Comparison of Northern and Southern Views

There is a growing interest in understanding consumer ethical actions in relation to their dealings with firms. This paper examines whether there are differences between Northern and Southern European Union (EU) consumers' perceptions of ethical consumer behaviour using Muncy and Vitell's (1992) Consumer Ethics Scale (CES). The study samples 962 university students across four Northern EU countries (Germany, Denmark, Scotland, The Netherlands) and four Southern EU countries (Portugal, Spain, Italy, Greece). Some differences are identified between the two samples, which might question the ability of organisations to consider the EU as one homogeneous market.     

Windfall Profits Under Pollution Permits and Output-Based Allocation

This paper analyzes the implementation of pollution permits. It focuses on the distributional impacts linked with the stringency of output-based allocation when two sectors are covered by the market for permits and the total cap is held constant. A new type of profit increase in sectors that are not exposed to international competition, when energy-intensive trade-exposed (EITE) sectors are granted output-based allocations, is demonstrated theoretically. The paper also illustrates a profit increase in the electricity sector in a possible fourth phase of the European Union Emission Trading Scheme, in which output-based allocation will be granted to EITE sectors, compared with the case in which all permits are auctioned.     

The role of ownership structure in integrated reporting policies

Integrated reporting (IR) is used to demonstrate a firm's capacity to create value in the short, medium, and long term. It can better represent existing relationships between the company and its stakeholders, with a particular focus on investors. Attention to IR has grown considerably in recent years. However, studies on the determinants of IR quality are still limited. This study aims to bridge this literature gap by being the first study to analyse the role of ownership structure in IR context. To this end, it uses agency theory and is based on a sample of 152 international companies that have adopted IR. The results indicate a positive effect of institutional ownership and a negative effect of ownership concentration, managerial ownership and state ownership on the quality of integrated reports. These results are also consistent with the level of alignment of integrated reports with the <IR> framework. To our knowledge, this is the first study that analyses the role of ownership structure in the IR policies.     

Winds of Trade: Passage to Zero-Emission Shipping

The shipping industry needs to decarbonize over the coming decades, but there are competing visions about how that will happen. While major shipping companies are looking to potential new fuels, including ammonia, other disruptors are already shipping small quantities of boutique goods, emission free, on sailboats harnessing the power of the wind. They are a reminder that all global trade used to travel by sail. Can wind propel us back to the future? There is a role for wind power in shipping as both a primary means of propulsion and a way to provide wind assistance to reduce a vessel’s fuel use. This article examines the possibilities and challenges for wind-based sea transport.     

Robust Small Area Estimation under Spatial Non‐stationarity

The effective use of spatial information in a regression‐based approach to small area estimation is an important practical issue. One approach to account for geographic information is by extending the linear mixed model to allow for spatially correlated random area effects. An alternative is to include the spatial information by a non‐parametric mixed models. Another option is geographic weighted regression where the model coefficients vary spatially across the geography of interest. Although these approaches are useful for estimating small area means efficiently under strict parametric assumptions, they can be sensitive to outliers. In this paper, we propose robust extensions of the geographically weighted empirical best linear unbiased predictor. In particular, we introduce robust projective and predictive estimators under spatial non‐stationarity. Mean squared error estimation is performed by two analytic approaches that account for the spatial structure in the data. Model‐based simulations show that the methodology proposed often leads to more efficient estimators. Furthermore, the analytic mean squared error estimators introduced have appealing properties in terms of stability and bias. Finally, we demonstrate in the application that the new methodology is a good choice for producing estimates for average rent prices of apartments in urban planning areas in Berlin.     

Endogenous timing of managerial delegation contracts in a unionized duopoly

In a multiple‐stage duopoly game with strategic delegation and unionized labor market, this paper analyzes whether firms' owners decide managerial incentive contracts sequentially or simultaneously. When firms compete in quantities, firms' owners can choose incentive contracts simultaneously or sequentially, depending on the unions' relative bargaining power and the degree of product differentiation. Instead, when firms compete in prices, firms' owners set incentive contracts sequentially with substitute goods and simultaneously with complement goods.     

Mark-ups, economies of scale and the role of knowledge spillovers in OECD industries

Using R&D-based models of economic growth as a foundation, this paper argues that market-driven knowledge creation is necessarily linked as an engine of productivity growth to economies of scale and market-power. A cost function and factor demand model is applied to a cross-country industry data set to study market-power, economies of scale and the role of knowledge in an integrated approach. Empirical results reveal the presence of market-power and economies of scale in all of the industries investigated. R&D and spillovers explain some of the productivity growth observed. Spillovers are identified as an external source of economies of scale.
