Learning-by-Exporting and Destination Effects: Evidence from African SMEs

Vast empirical evidence underscores that exporting firms are more productive than non-exporters. As governments accordingly pursue export-promoting policies we are interested in the firmness of these conclusions with respect to African small and medium sized enterprises (SMEs) and the influence of the destination of export trade. Using a micro-panel dataset from five African countries we confirm the self-selection. We apply propensity scores to match exporters and use a difference-in-difference methodology to test if African SMEs experience productivity gains because of export participation. Results indicate that African firms significantly learn-by-exporting. Manufacturers obtain significant performance improvements due to internationalization although this effect is moderated by export destination. Firms that export outside Africa become more capital intensive and at the same time hire more workers. In contrast we find evidence that exporters within the African region significantly downsize in capital intensity. Results regarding skill-bias of internationally active firms are mixed, where exporters within the region expand in size and hire more relatively unskilled workers.learning-by-exporting, destination effects, firm-level, Africa, propensity scores

Locked-in and Sticky Textbooks: Mainstream Teaching of the Money Supply Process

Current macro-economic textbooks provide a fatally misleading description of the money supply process in modern economies. Over the past 20 years Post Keynesian authors have established conclusively that despite strictly-enforced cash reserve requirements, changes in the supply of bank deposits are not determined exogenously by central bank open market operations, but are endogenously determined by changes in bank borrowers’ demand for credit. Nevertheless the vast majority of undergraduate macroeconomic textbooks continue to teach the high-powered-base “money-multiplier” paradigm that the supply of money is exogenously determined by the central bank. Few texts recognize that interest rate targeting renders the high-powered base endogenous. This paper summarizes the extent mainstream macroeconomic textbooks are “locked in” and “sticky,” and fail both in the teaching of monetary policy and in proper scientific discourse.macroeconomic textbooks, money supply, endogenous money paradigm, EMP, Post Keynesian economics, paradigm shift

Regional determinants of FDI in China: A new approach with recent data

We empirically investigate the factors that drive the uneven regional distribution of foreign direct investment (FDI) inflows to China.s 31 provinces from 1995 to 2006. The aim of this paper is to explain the investment patterns in (partly) foreign funded firms across these provinces. We use factor analysis and derive four factors that may drive FDI: institutions, labor costs, market potential, and geography. The factor analysis then structures our dataset to concentrate on these four clusters consisting of 42 province specific and time-varying items. Factor analysis not only helps us to identify the latent dimensions which are not apparent from direct study, but also facilitates econometrics with reduced number of variables. We apply fixed effects panel estimation and GMM to account for endogeneity. In line with theoretical predictions we find that foreign investors choose and invest more in provinces with better institutions, lower labor costs, and larger market size. Nonlinear results denote that the positive effects of infrastructure and market potential on FDI are complementary to each other, which is in line with the economic geography literature. In particular the effect of market size on FDI is larger in provinces with better institutions. Sub-sample study confirms the existences of a large disparity between East and West. In the poorer large western provinces FDI is strongly driven by the geographical factor in contrast to the east of China where institutions play a significant role to build the .factory of the world.. Robustness tests indicate that two sub-dimensions of institutions, namely infrastructure and governance, are important to determine the location choice of FDI in China.FDI, China, factors analysis, regional and spatial distribution of FDI, location choice

Estimating reliability coefficients with heterogeneous item weightings using Stata: A factor based approach

We show how to estimate a Cronbach's alpha reliability coefficient in Stata after running a principal component or factor analysis. Alpha evaluates to what extent items measure the same underlying content when the items are combined into a scale or used for latent variable. Stata allows for testing the reliability coefficient (alpha) of a scale only when all items receive homogenous weights. We present a user-written program that computes reliability coefficients when implementation of principal component or factor analysis shows heterogeneous item loadings. We use data on management practices from Bloom and Van Reenen (2010) to explain how to implement and interpret the adjusted internal consistency measure using afa.afa, factor analysis, Cronbach's alpha, reliability, heterogeneous scale construction,latent variable

Evaluation of Real-Life Investigational Use of Enoximone in Asthma, the Third Step in Drug Repurposing:A Preliminary Report

BACKGROUND: The population of uncontrolled asthma patients represents a large therapeutic burden. The PDE3-inhibitor enoximone is a strong and quick bronchodilator and is known to successfully treat life-threatening bronchial asthma (status asthmaticus). Translational mice models showed anti-inflammatory effects when PDE3 was targeted. METHODS: Here, we investigated the effectiveness of PDE3-inhibitor enoximone as oral treatment for chronic asthma in a real-life off-label setting. Investigational use of PDE3-inhibitor enoximone: 51 outpatients (age 18–77) with chronic asthma were followed using off-label personalized low doses of the PDE3-inhibitor enoximone. Duration of treatment was 2–8 years. RESULTS: Four groups could be distinguished as follows: The first group includes patients who use enoximone as an add-on, because it helps them in maintaining a better general wellbeing; they still use their traditional medication (n = 5). The second group consists of patients who use enoximone and were able to phase down their traditional medication without deterioration of their asthma symptoms (n = 11). The third group comprises patients who were able to discontinue their traditional medication and use only enoximone without deterioration of their asthma symptoms (n = 24). The last one has patients who, after having used enoximone for some time, saw their symptoms disappear and now use no medication at all, not even enoximone (n = 11). All patients reported improvement or at least alleviation of their asthma symptoms. All patients reported a better quality of life and greater drug compliance. CONCLUSION: The evaluation shows that PDE3-inhibitor enoximone is a viable alternative for or addition to current asthma therapeutics, as both add-on and stand-alone, considerably reducing the use of LABAs/SABAs/ICS, with no or negligible side effects. Additional studies are advisable

Learning-by-Exporting and Destination Effects: Evidence from African SMEs

Vast empirical evidence underscores that exporting firms are more productive than non-exporters. As governments accordingly pursue export-promoting policies we are interested in the firmness of these conclusions with respect to African small and medium sized enterprises (SMEs) and the influence of the destination of export trade. Using a micro-panel dataset from five African countries we confirm the self-selection. We apply propensity scores to match exporters and use a difference-in-difference methodology to test if African SMEs experience productivity gains because of export participation. Results indicate that African firms significantly learn-by-exporting. Manufacturers obtain significant performance improvements due to internationalization although this effect is moderated by export destination. Firms that export outside Africa become more capital intensive and at the same time hire more workers. In contrast we find evidence that exporters within the African region significantly downsize in capital intensity. Results regarding skill-bias of internationally active firms are mixed, where exporters within the region expand in size and hire more relatively unskilled workers

A Collective Imaginary and a Proposition for Change

This article focuses upon young people’s negative stress and anxiety in an educationsetting through a metamodern lens. The driving question of this project is the recurring issue: given the many factors that stress young people these days, how can we address those stressors? The aim is to shed some light on what educators can do to help young persons who live with anxiety. We also aim to create a short publication of received responses to forward to education authorities worldwide. In discussing the issue, we are drawing upon our personal experiences, creative processes, and recognized research from multicultural practitioners in the disciplines of medicine, education, art, sociology, and philosophy. The focus will not be on theoretical solutions, but on practical, creative ones. Metamodern attitudes propose that past texts can hold ever renewed relevance for the present. Accordingly, this narrative is told in an epistolary format complemented by a questionnaire and contemporary responses to an essay written in the middle of modernity some 80 years ago by New Zealand born kinetic artist Len Lye in collaboration with British writer Robert Graves, “Individual Happiness Now: A Definition of Common Purpose”. Responding to Lye’s essay “in the now of immediate action” calls for a focus upon “timing” our “position” in the world and an ethics of care, as well as endeavours to “stimulate [the] dormant intensity” of the present
