PRODUCTIVITY SPILLOVERS FROM MULTINATIONAL ACTIVITY TO LOCAL FIRMS IN IRELAND. OECD PRODUCTIVITY WORKING PAPERS No. 16, November 2018

As well as their direct effects on output and employment, the attraction of foreign direct investment is sometimes argued to provide further economic benefits through spillover effects that potentially increase the productivity performance of domestic firms. Empirical evidence on these indirect effects has however tended to be mixed. This paper uses Irish firm-level data on both manufacturing and services firms to re-examine and update evidence on intra-industry and intra-region spillovers and then extends the previous research by examining if spillovers are more likely to occur through supply chain linkages. In addition, we consider the heterogeneity of investors and allow the spillover effects to differ for foreign affiliates owned by EU and non-EU based parent companies. Finally, we examine the role of domestic firms’ absorptive capacity in conditioning the effects of spillovers from multinationals on their productivity. Overall, we find limited evidence or a negative link between the presence of foreign-owned firms and the productivity of domestic firms in the same industry or the same region. Examining forward and backward linkages through supply chains indicates that on average, selling to foreign-owned firms had a positive effect while buying from foreign owned firms had a negative effect on the average productivity of domestic firms. Finally, considering the absorptive capacity of domestic firms and allowing the spillover effects to differ depending on the origin of the parent companies, we find that the positive productivity spillovers come from supply chain linkages between domestic firms investing in R&D and foreign affiliates of multinationals with headquarters based outside the EU

Home versus Host Country Effects of FDI: Searching for New Evidence of Productivity Spillovers

This paper investigates the effects of both inward and outward foreign direct investment (FDI) on productivity in manufacturing and services sectors. The main novelty is the analysis of the spillover effects of outward FDI that may occur outside the investing firms on the rest of the home country. Our results based on panel data from Estonia do not indicate much spillover effects of outward or inward FDI that are robust to different specifications of the estimated model. There is substantial heterogeneity in the findings on spillovers across different specifications of the model or sector studied.http://deepblue.lib.umich.edu/bitstream/2027.42/57200/1/wp820 .pd

Failure detection and isolation investigation for strapdown skew redundant tetrad laser gyro inertial sensor arrays

The degree to which flight-critical failures in a strapdown laser gyro tetrad sensor assembly can be isolated in short-haul aircraft after a failure occurrence has been detected by the skewed sensor failure-detection voting logic is investigated along with the degree to which a failure in the tetrad computer can be detected and isolated at the computer level, assuming a dual-redundant computer configuration. The tetrad system was mechanized with two two-axis inertial navigation channels (INCs), each containing two gyro/accelerometer axes, computer, control circuitry, and input/output circuitry. Gyro/accelerometer data is crossfed between the two INCs to enable each computer to independently perform the navigation task. Computer calculations are synchronized between the computers so that calculated quantities are identical and may be compared. Fail-safe performance (identification of the first failure) is accomplished with a probability approaching 100 percent of the time, while fail-operational performance (identification and isolation of the first failure) is achieved 93 to 96 percent of the time

Do economic models tell us anything useful about Cohesion Policy impacts? A comparison of HERMIN, QUEST and ECOMOD

An ex-ante impact analysis of EC Cohesion Policy investment programmes for the period 2007-2013 was recently carried out on behalf of the European Commission (DG Regional Policy) using three different economic models: the QUEST II model of DG-ECFIN, the ECOMOD model of EcoMod Network/Free University of Brussels and the COHESION system of HERMIN models of GEFRA/EMDS. The main results were published in the most recent Fourth Cohesion Report (EC, 2007), and it turned out that different models gave different results. In some cases the differences were very big and pointed to quite different conclusions about the impact of the European Cohesion Policy on growth and employment impacts. In order to progress the debate on the usefulness of model-based policy impact analysis, we first set out the wider context within which EC Cohesion Policy is designed, implemented and evaluated. We then present a brief summary of the main findings of the model-based analysis in terms of impacts on aggregate GDP and total employment. We conclude with a discussion of possible reasons why two of the models – QUEST and HERMIN - may be producing different results.

Intelligent Learning Algorithms for Active Vibration Control

YesThis correspondence presents an investigation into the comparative performance of an active vibration control (AVC) system using a number of intelligent learning algorithms. Recursive least square (RLS), evolutionary genetic algorithms (GAs), general regression neural network (GRNN), and adaptive neuro-fuzzy inference system (ANFIS) algorithms are proposed to develop the mechanisms of an AVC system. The controller is designed on the basis of optimal vibration suppression using a plant model. A simulation platform of a flexible beam system in transverse vibration using a finite difference method is considered to demonstrate the capabilities of the AVC system using RLS, GAs, GRNN, and ANFIS. The simulation model of the AVC system is implemented, tested, and its performance is assessed for the system identification models using the proposed algorithms. Finally, a comparative performance of the algorithms in implementing the model of the AVC system is presented and discussed through a set of experiments

Firm-level Analysis of Globalization: A Survey

This paper extensively reviews empirical studies that analyze the various impacts of the globalization phenomenon on corporate activities by using micro data. First, we set up a flow chart describing how globalization leads to national productivity enhancement. Secondly, we summarize the hypotheses and the methods explored in 13 lines of literature on globalization, which this flow chart maps. Thirdly, we discuss further possible avenues for micro data analysis. Finally, we provide some suggestions on statistics-related policies.Firm-level data; Globalization; Productivity.
