Persistence of economic uncertainty: a comprehensive analysis

One of the most heavily researched and cited issue in applied economics is the relationship of uncertainty indices with the financial and macroeconomic variables. While the statistical features of financial and macroeconomic variables have been thoroughly examined, virtually nothing has been done to examine uncertainty indices under the statistical perspective. In this paper, we focus on two primary characteristics of uncertainty indices: persistence and chaotic behaviour. In order to evaluate the persistence and the chaotic behaviour we analyse 72 popular uncertainty indices constructed by forecasting models, text mining from news articles and data mining from monetary variables to measure the Hurst and Lyapunov exponents in rolling windows. The examination in rolling windows provides a dynamic evaluation of the specific characteristics revealing significant variations of persistence and chaotic dynamics with time. More specifically, we find that almost all uncertainty indices are persistent, while the chaotic dynamics are detected only sporadically and for certain indices during recessions of economic turbulence. Thus, we suggest that the examination of persistence and chaos should be a prerequisite step before using uncertainty indices in economic policy models.     

On exchange-rate movements and gold-price fluctuations: evidence for gold-producing countries from a nonparametric causality-in-quantiles test

The links between exchange-rate movements and gold-price fluctuations have been extensively studied in earlier research using various econometric techniques. Our contribution to this research is that we apply a novel nonparametric causality-in-quantiles test to study the causal links between exchange-rate movements and gold-price fluctuations. We use daily data for the sample period 1994–2015 for major gold-producing countries to illustrate the novel test. We find that, for the majority of countries, gold-price fluctuations help to predict in sample the returns and the volatility of exchange rates. While exchange-rate movements predict in sample gold volatility, they do not predict gold returns.     

The time-varying correlation between output and prices in the United States over the period 1800–2014

In this study, we examine the time-varying correlations between output and prices, while controlling for the impact of the monetary policy stance and output and inflation uncertainties over the period 1800–2014. The results of the empirical analysis reveal that the dynamic correlations of output and prices were typically negative, suggesting a countercyclical behaviour of prices, apart from the early 1840s and from the beginning until the middle of the 20th century, when the correlation was positive, indicating a procyclicality of prices. A historical decomposition analysis based on a sign-restricted structural vector autoregressive model is able to relate the procyclical and countercyclical behaviour to the predominance of aggregate supply and aggregate demand and/or monetary policy shocks, respectively. Moreover, inflation uncertainty (monetary policy stance) was found to have a positive (negative) effect on inflation over the last 215 years.     

Red,blue, and purple firms: Organizational political ideology and corporate social responsibility

Research summary : Why do firms vary so much in their stances toward corporate social responsibility (CSR )? Prior research has emphasized the role of external pressures, as well as CEO preferences, while little attention has been paid to the possibility that CSR may also stem from prevailing beliefs among the body politic of the firm. We introduce the concept of organizational political ideology to explain how political beliefs of organizational members shape corporate advances in CSR . Using a novel measure based on the political contributions by employees of Fortune 500 firms, we find that ideology predicts advances in CSR . This effect appears stronger when CSR is rare in the firm's industry, when firms are high in human capital intensity, and when the CEO has had long organizational tenure . Managerial summary : Why do firms vary in their stances toward corporate social responsibility (CSR )? Prior research suggests that companies engage in CSR when under pressure to do so, or when their CEOs have liberal values. We introduce the concept of organizational political ideology, and argue that CSR may also result from the values of the larger employee population. Introducing a novel measure of organizational political ideology, based on employees' donations to the two major political parties in the United States, we find that liberal‐leaning companies engage in more CSR than conservative‐leaning companies, and even more so when other firms in the industry have weaker CSR records, when the company relies heavily on human resources and when the company's CEO has a long organizational tenure .

International comparison of returns from conventional,industrial and 52-week high momentum strategies

The performance of industrial and 52-week high momentum strategies is compared to the conventional strategy, using a large sample of stocks drawn from multiple countries covering a quarter of century to 2007. The sample of 51,879 stocks in 51 countries removes the potential for criticism, such as data mining, and provides more generalisable findings and knowledge concerning the robustness and usefulness of return from momentum strategies. Both the industry and 52-week high strategies generate positive returns but neither is greater than the conventional momentum strategy. A new 52-week high industry momentum strategy is examined and it achieves a similar result.     

Empirical organizational‐level examinations of agency and collaborative predictions of performance‐contingent compensation

Competitive predictions regarding the relationships between: (a) monitoring and agent tenure, and (b) performance‐contingent compensation are derived from agency theory and collaborative perspectives. These results are tested in a within‐industry (trucking) sample and in a cross‐industry sample. The results partially support both perspectives, particularly with respect to monitoring and agent tenure. Implications of the results for theory and practice are discussed.

Are short‐term effects of pollution important for growth and optimal fiscal policy?

We study optimal fiscal policy in a stock‐flow model of the environment within an endogenous growth framework, where some pollutants have a lasting impact on environmental quality which is restored through abatement expenditure, while others dissipate and hence, have a short‐term effect on the environment. All pollutants, however, affect the productivity of a public good negatively. Given that short‐term pollution, although it dissipates, is irreversible in this sense, a government cannot ignore its negative effects since this type of pollution lowers the productivity of all inputs. We find that a larger negative effect of short‐term pollutants as well as a higher congestion effect of private capital leads to corrective fiscal policies with higher optimal income tax and abatement expenditure rates, which have favorable growth consequences. Interestingly, we find that the rate of short‐term pollution does not affect optimal fiscal policy while that of the long‐term pollution does.     

Pseudo maximum likelihood estimation of spatial autoregressive models with increasing dimension

Pseudo maximum likelihood estimates are developed for higher-order spatial autoregressive models with increasingly many parameters, including models with spatial lags in the dependent variables both with and without a linear or nonlinear regression component, and regression models with spatial autoregressive disturbances. Consistency and asymptotic normality of the estimates are established. Monte Carlo experiments examine finite-sample behaviour.     

Unionized Labour Market,Unemployment Allowances,Productive Public Expenditure And Endogenous Growth

An endogenous growth model with unionised labour market is developed to analyse the interaction between the tax financed productive public expenditure policy and the unemployment benefit policy. We consider both ‘Efficient Bargaining’ model and ‘Right to Manage’ model; and analyse properties of balanced growth rate maximising income tax policy as well as effects of unionisation. This growth rate maximising income tax rate exceeds the competitive output share of the public input in the presence of an unemployment benefit scheme. The growth effect of unionisation in the ‘Efficient Bargaining’ model and in the ‘Right to Manage’ model are different.
