Regulating the Platform Economy: How to Protect Workers While Promoting Innovation

The rise of the platform economy has made it a topic of great interest among European policymakers, as evidenced by the European Commission’s 2016 Communication “A European agenda for the collaborative economy”. The regulatory challenges facing policymakers are manifold, ranging from taxation to competition policy to worker protection. Furthermore, many basic aspects of the platform economy are unclear, such as its size, the number of workers who take part in it and, indeed, its very definition. What types of regulation are necessary to ensure that the benefits of the platform economy are maximised for all Europeans? How can the productivity gains associated with the platform economy be distributed throughout society? Perhaps most importantly, how can policymakers support innovation while also protecting consumers, workers and communities?     

Collaborative Economy: Market Design and Basic Regulatory Principles

The rise of the collaborative economy platforms reveals that policymakers need to start thinking about how to introduce flexibility in the provision of services in these formal relationships with adequate protection for all of the involved parties.     

Exchange Rates and Stock Prices in the MENA Countries: What Role for Oil?

This paper considers the linkage between stock prices and exchange rates in four MENA (Middle East and North Africa) emerging markets. In contrast to the existing evidence that uses a global market index to uncover such a relationship it is found that for the sample countries oil prices emerge as the dominant factor in the above relationship. The paper considers the presence of regime shifts and evidence is found of cointegration only for the period following the 1999 oil price shock. Readjustment towards equilibrium in each stock market occurs via oil price changes. Finally, a number of robustness checks are performed and persistence profiles produced.     

Are Full Employment and Social Cohesion Possible Under Financialization?

Unemployment and unequal income distribution were singled out by J.M. Keynes, in the General Theory, as major faults of capitalist economies. This paper argues that there is a negative relationship between financialization and unemployment. In particular, we develop a simple Post Keyneian/Kaleckian model and explore distribution as well as institutional channels through which financialization might have negatively affected the employment performance of capitalist economies, undermining the social cohesion and egalitarian development. Furthermore, we argue that in the face of financialization full employment is likely to be attainable under the institutionalization of an Employer of Last Resort (hereafter ELR) policy strategy.     

COMMON STOCHASTIC TRENDS AMONG THE CYPRUS STOCK EXCHANGE AND THE ASE,LSE AND NYSE

Common stochastic trends among major international stock price indices have been an intensively analysed issue mainly as a result of the 1987 stock market crash and the need for policy coordination in financial markets. This paper investigates the existence of common stochastic trends among an emerging equity market, the Cyprus Stock Exchange, and three mature equity markets, namely the Athens Stock Exchange (ASE), the London Stock Exchange (LSE) and the New York Stock Exchange (NYSE).     

Nonlinear Alternatives to Unit Root Tests and Public Finances Sustainability: Some Evidence from Latin American and Caribbean Countries*

We analyse the sustainability of government debt for Latin American and Caribbean countries employing unit‐root tests with nonlinear alternative hypotheses and examine the robustness of our results against those from unit‐root tests with breaks and threshold nonlinearities. We show that, in general support for sustainability substantially improves when nonlinear mean reversion is taken into account. We also find that the results obtained from applying various tests with nonlinear alternatives, although broadly consistent, are not identical. This suggests that reliance on a single unit‐root test for assessing fiscal policy sustainability may be misleading.     

Political cycles under external economic constraints: Evidence from Cyprus

This paper examines the presence of political cycles in a small open economy using data from Cyprus over the period 1978–2006, and explores their conditionality upon external economic constraints, such as globalization and European integration. Two basic results emerge. First, we find evidence of partisan shifts in economic policies and outcomes, although these effects seem to decrease as globalization progresses, and to disappear in the run-up to EMU. This implies that, while partisan cycles can emerge under a certain domestic political setting, the sensitivity of an economy to globalization pressures and the challenges resulting from EU/EMU membership can lead to their weakening. Second, we find evidence of electoral shifts in certain, more visible, subcomponents of the fiscal balance. However, in contrast to partisan distinctions, these opportunistic effects become more pronounced as globalization proceeds. It seems that constraints imposed on the ability of politicians to ingratiate themselves with partisans, may actually strengthen their incentives to engage in electioneering.     

The dynamics of inflation: a study of a large number of countries

Over the last twenty years the statistical properties of inflation persistence has been the subject of intense investigation and debate without reaching a unanimous conclusion yet. In this article we attempt to shed further light to this debate using a battery of econometric techniques in order to provide robust evidence on the degree of inflation persistence and whether this has changed during the period in which several countries have followed inflation-targeting regimes or new monetary regimes. We consider the inflation rates of thirty developed and emerging economies using quarterly data for the period 1958 to 2007 which include alternative monetary policy regimes. The coefficient of the inflation parameter is estimated by Ordinary Least Squares (OLS), Autoregressive Moving Average (ARMA) and Autoregressive Fractionally Integrated Moving Average (ARFIMA) models. Furthermore, the grid-bootstrap Median Unbiased (MUB) estimator approach developed by Hansen (1999) is used to estimate the finite sample OLS estimates coupled with the 95% symmetric confidence interval. We also examine parameter stability of persistence coefficients by estimating a model with time-varying parameters.     

Mean and Variance Causality between Official and Parallel Currency Markets: Evidence from Four Latin American Countries

This paper examines the issue of mean and variance causality across four Latin American official and black markets for foreign currency using monthly data for the period 1976–1993. We apply a recent test developed by Cheung and Ng (1996) in order to test for mean and variance spillovers. The main findings are: (1) In contrast to the findings of previous studies, EGARCH-M processes characterize each bilateral exchange rate series in both markets; (2) There is substantial evidence of causality in both mean and variance with the causality in mean largely being driven by the causality in variance; and (3) The results indicate that the major exporter of causality is the Mexican black market with the black market of Argentina and the black and official markets of Brazil being the smallest contributors.
