ON THE HETEROGENEOUS EMPLOYMENT EFFECTS OF OFFSHORING: IDENTIFYING PRODUCTIVITY AND DOWNSIZING CHANNELS
2014
I. INTRODUCTION For the most part of the last two decades Germany suffered from a hangover of the reunification boom, an overvalued exchange rate, high unemployment, and low growth--so The Economist famously named it the "Sick Man of Europe." At the same time, German companies were relocating production, restructuring, and offshoring. The general public associated such offshoring activities--not only in Germany--with plant closures which made the headlines and confirmed the perception that offshoring was a job killer.1 What usually does not make the news is that such downsizing effects of offshoring may be counterbalanced by productivity effects in the restructuring firm. Depending on their…
Within and between firm trends in job polarization : the roles of globalization and technology
2019
AbstractWe analyze occupational polarization within and across firms using a census of matched employer–employee panel data from Finland in the period of 2000–2014. As in most industrialized countries, the Finnish occupational distribution has polarized over the last decades. Using decomposition analysis, we find that jobs involving low-level service tasks increase mostly through the entry dynamics, while the high-level abstract task share increases largely within continuing firms. Worker-level occupational mobility points to some skill upgrading within continuing firms, while labor force entry and retirement contribute the polarizing trend. Instrumental variables (IVs) regressions confirm …
Offshoring in the European Union: a Study of the Evolution of the Tax Burden
2017
One of the most serious effects of offshoring is tax avoidance, which harms the economies of the affected regions. In an attempt to eradicate tax avoidance, the EU seeks to establish tax harmonization across its Member States. Based on data for 2006-2014, this study analyzes the historical evolution and current trends of a convergence or divergence of the tax burden for 15 EU Member States. The effective tax rate was used to assess the tax burden. This study used a novel approach to analyze the tax burden and conducted a cluster analysis to examine changes in the effective tax rates between 2006 and 2014. The results imply that when the economy prospers, effective tax rates tend to converge…
Fault Diagnostics for Electrically Operated Pitch Systems in Offshore Wind Turbines
2016
This paper investigates the electrically operated pitch systems of offshore wind turbines for online condition monitoring and health assessment. The current signature based fault diagnostics is developed for electrically operated pitch systems using model-based approach. The electrical motor faults are firstly modelled based on modified winding function theory and then, current signature analysis is performed to detect the faults. Further, in order to verify the fault diagnostics capabilities in realistic conditions, the operating profiles are obtained from FAST simulation of offshore wind turbines in various wind conditions. In this way, the applicability of current signature analysis for …
A Two-Stage Fault Detection and Classification Scheme for Electrical Pitch Drives in Offshore Wind Farms Using Support Vector Machine
2019
Pitch systems are one of the components with the most frequent failure in wind turbines. This paper presents a two-stage fault detection and classification scheme for electric motor drives in wind turbine pitch systems. The presented approach is suitable for application in offshore wind farms with electric pitch systems driven by induction motors as well as permanent magnet synchronous motors. The adopted strategy utilizes three-phase motor current sensing at the pitch drives for fault detection and only when a fault condition is detected at this stage, features extracted from the current signals are transmitted to a support vector machine classifier located centrally to the wind farm. The …
An Exploratory Case Study of Offshore Outsourcing: Problems in Multicultural Settings
2014
Outsourcing means using factors which are external to an organization to perform its functions whereas offshore outsourcing relies on using foreign resources to perform those functions. We focus in this paper on offshore outsourcing of information systems (ISs). We have conducted an exploratory case study of outsourcing IS support services. The services have been outsourced by a supplier organization which has been based in Finland. Main parts of its customer support services have been allocated to so-called production centers, which have been located in three countries; Latvia, India, and the Philippines. We have gathered qualitative data from nine experts via theme-based interviews. The e…
Risk management in offshore outsourcing of software production using the ICT-supported unified process model: A cross-case study
2008
Successful execution of ICT-supported unified process of offshore outsourcing (ICT-SUPOO) of software development can offer various important benefits. However, ICT-SUPOO of software development is very complex and risky, and often fails. Almost no empirical studies are available on the risk factors that affect the ICT-SUPOO. The objective of this study is to investigate the key risk factors associated with ICT-SUPOO, understand how they create risks, and how the risks can be alleviated. We carry out a multiple case study from both of the vendorpsilas and clientpsilas sites, where professionals with extensive experience in managing offshore outsourcing of software development were interview…
H∞ static output-feedback control design with constrained information for offshore wind turbine system
2013
Abstract This paper deals with H ∞ static output-feedback control design with constrained information for offshore wind turbines. Constrained information indicates that a special zero–nonzero structure is imposed on the static output-feedback gain matrix. A practical use of such an approach is to design a decentralized controller for a wind turbine. This will also benefit the controller in such a way that it is more tolerant to sensor failure. Furthermore, the model under consideration is obtained by using the wind turbine simulation software FAST. Sufficient conditions to design an H ∞ controller are given in terms of Linear Matrix Inequalities ( LMI s ). Simulation results are given to il…
Wave Energy Assessment along Sicilian Coastline, Based on DEIM Point Absorber
2017
The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around the island. A point absorber is present in order to exploit this source. Two scenarios are presented, with two different levels of energy production.
Italian incentive strategy and regulations on small wind power turbines: A critical overview
2016
Small wind power industry in Italy had its kick-start in 2009, after the Government implemented two measures introducing both the simplified regime and incentive rates for small wind power plants. In the last six years, a lot of plants and small wind turbines have been installed in Italy, especially in the South. Aim of this paper is to examine how local standards, incentive policy and regulations have affected the spread of small wind turbines in Italy. After examining national and regional legislation, an analysis of the data on the penetration of wind systems in Italy has been carried out, with particular attention to six Southern regions (Basilicata, Calabria, Campania, Apulia, Sardinia…
