This study examines the reaction of four major emerging equity markets of the Pacific Rim to the US oil market fear index (i.e., the Chicago Board of Trade Volatility Index, OVX). The OVX is designed to perform as a leading indicator of the volatility in crude oil markets. Our study examines the daily data for the period of 2014 through 2019. We excluded data for the extraordinary and transitory COVID-19 time period. We found that, during this period, there were four significant breaks in the data. Impulse responses from the structural vector autoregressive (SVAR) estimation show that in the second and third subperiods, from December 2016 through December 2018, the volatility of the equity markets of Hong Kong, Shanghai, Seoul, and Taiwan responded to structural shocks to the OVX. Nonlinear Granger causality tests confirmed these findings. This period is characterized by geopolitical crises, like nuclear proliferation on the Korean Peninsula and lingering complications surrounding the Brexit referendum. JEL classification numbers: G10, G15, G17

The aim of this article is to analyze the determinants of government spending on health in the West African Economic and Monetary Union (WAEMU) area. To do this, we have collected panel data on which an autoregressive Distributed Lag model (ARDL) approach is applied at the end of econometric tests (Stationarity and Co-integration). As main results, population growth, use of mosquito nets, hospital beds, number of doctors, nurses - midwives, corruption scores and political stability are responsible for government spending. To be short, we can note that these determinants are both supply and demand factors. Thus, government action is not only political (ensuring political stability, good governance), but also medical (ensuring the professionalism of healthcare staff and raising awareness among the population about the use of Treated Mosquito nets with limited duration of action).

The essential goal of trend-following investing is to precisely identify where the uptrend and downtrend are located. This paper thus provides a two-layer stacking technique, which is a novel ensemble learning approach, to predict such trends for the Taiwan Top 50 ETF. The proposed stacking technique stacks the predictors of support vector machine (SVM), multi-layer perception (MLP), adaptive boosting (Adaboost), and extreme gradient boosting (Xgboost), presenting empirical results whereby following the trends obtained from the stacking technique can generate positive returns and beat both conventional moving-average crossover and buy-and-hold strategies.

The economic flows measured by the national accounts, which are associated with transactions of goods, services, and assets, as well as transfers, all represent interactions between institutional units, to whom legal responsibility for their actions and the fulfilment of specific economic functions is recognized. These flows are defined by the underlying system – the System of National Accounts (SNA) as being transactions. When represented in the matrix form, depending on the classification and organization of the institutional units, at the origin and the destination of the corresponding flows, the “from-whom-to-whom” transactions can be measured and modelled, benefiting from the underlying network of linkages. By adopting the nomenclatures and rules of the current version of the above-mentioned system (SNA 2008), this study uses a top-down methodology to design a matrix representation of the above-mentioned transactions - the Social Accounting Matrix (SAM). Empirical and theoretical descriptions of the economic activity of a country (Portugal is used as the illustrative case), made possible by the use of the numerical and algebraic versions of a SAM, are adopted to approach the multiplier effects of policy measures and the corresponding economic adjustments.

Productivity growth is an essential ingredient for achieving long-term economic growth and sustainable development. In the absence of such growth, economic growth is not achievable. Accordingly, this paper examines economic resilience through multiple productivity channels within the United States, Japan and South Korea. Adopting a Kaleckian post-Keynesian approach, productivity growth is constructed as a function of investment, capacity utilisation, indicators of financial development, and an indicator of fiscal policy. Utilising annual historical data from 1980-2019, this paper adopts Autoregressive Distributed Lag (ARDL) models, Vector Autoregressive-based Impulse Response Functions (IRF) and Variance Decompositions (VD) to examine the resilience of productivity growth through the speeds of adjustment after an external shock. Results show that long and short-run unidirectional causality between productivity growth and the explanatory variables exists amongst all economies through the error-correction terms (ECT) and ARDL models. When imposing a simulated one-time S.D. shock upon the explanatory variables, differing speeds of adjustment and recovery processes in the long-run are present. As such, the strength of causal relationships amongst productivity growth and the explanatory variables ultimately affects speeds of adjustment and hence recovery.
