This paper performs robust bilateral Granger causality tests for stock prices, consumer sentiment, and economic activity for the US and the UK. The robust test procedures involve the use of recently developed time series analysis of nonstationary data with possible structural breaks. Applying a battery of such tests, the paper finds the underlying data to be generally nonstationary and noncointegrated, even after allowing for possible breaks in the data, thus implying that the standard bilateral Granger causality tests are robust. The empirical results indicate the presence of unidirectional causality from stock prices to consumer sentiment for both countries. Given that stock prices drive consumer sentiment, we perform additional causality tests to determine the effect of consumer sentiment on the economy. Our finding of a unidirectional causality from consumer sentiment to the economy in both countries is consistent with a chain of causality from stock prices to consumer sentiment to the economy.

Grain Prices

This paper investigates the co-movement and asymmetric interactions between energy and grain prices, based on the evidence from the crude oil and corn markets, the most important energy and grain markets, respectively. Time series analysis indicates that there is a consistent trend between the crude oil price and corn price with a significant positive correlation coefficient 0.7471 during the sampling period, from January 2008 to February 2016. In addition, we find that there is a long-run equilibrium relationship between the two commodities’ prices. Moreover, while linear Granger causality tests suggest that there is a two-way Granger causality relationship between the price changes in the two markets, non-linear Granger causality tests suggest that there is only a one-way causality relationship from corn to oil price. However, both linear and non-linear Granger causality tests indicate the asymmetry of causality relationship between the two markets (the price change in corn market can more significantly Granger cause the change in crude oil market). Further analysis suggests that the contribution of the corn market to price discovery in a large commodity market is larger than that of the crude oil market.

Smooth Breaks

AbstractIgnored structural breaks in a VAR result in a misspecified model such that Granger causality tests are improperly sized; there is a bias towards a rejection of the null hypothesis of non-causality even when the null is correct. Instead of modeling structural breaks as being sharp, changes in the relationship between the maize and petroleum markets are likely to have occurred gradually. We show the flexible Fourier form has good size and power properties in testing for smooth structural change in a VAR. When applied to a VAR including maize and oil prices, we uncover important linkages between the two markets.

Panel data show that between 2001 and 2014 Norwegian industries’ increasing aggregated operating profits per employee increased average wages and wage inequality. The data imply that increasing profits, perhaps unsurprisingly, induce a wage premium. The data further imply that employees earning high incomes at the outset had the highest wage increase percentage-wise. Decreasing operating profits per employee had opposite but less robust effects on average wages and wage inequality. Panel data Granger causality tests finally showed that average wages, but not wage inequality, reversely and positively affect operating profits per employee.

AbstractThere is a debate in Argentina about the effectiveness of mandatory lockdown measures in containing COVID-19 that lasts five months making it one of the longest in the World. The population effort to comply the lockdown has been decreasing over time given the economic and social costs that it entails. We contributes by analyzing the Argentinian case through information of mobility and contagion given answers to recurrent questions on these topics. This paper aims to fill the gap in the literature by assessing the effects of lockdown measures and the regional relaxation on the numbers of rate of new infections. We also respond to issues of internal political discussion on regional contagion and the effect of marches and unexpected crowd events. We use pool, fixed and random effects panel data modeling and Granger causality tests identifying relations between mobility and contagion. Our results show that lockdown in Argentina has been effective in reducing the mobility but not in way that reduces the rate of contagion. Strict lockdown seems to be effective in short periods of time and by extend it without complementary measures loss effectiveness. Contagion rate seems to be discretely displaced in time and resurging amidst slowly increasing in mobility.

Abstract This paper evaluates the factors responsible for maintaining substantial military expenditures in Greece and Turkey. The presented research encompasses theoretical and empirical aspects. First, defense spending by both countries was analyzed based on statistical data from international sources. Next, the theoretical determinants of budgetary spending are reviewed, which consider political, economic and military factors behind high expenditures on the army in Greece and in Turkey. Finally, Granger causality tests is applied to determine whether a causal relation between variables exists in the case of these two countries. We conclude that defense expenditures in Greece and Turkey exceed the NATO average, but are relatively low relative to those of selected Middle Eastern countries. Our results indicate that high military spending level in Turkey is mainly driven by national security concerns, whereas an economic driver prevails in Greece.
