Are living standards converging?

We re-address the convergence issue that is so prominent in the economic growth literature and present evidence as to what extent there is convergence across measures of living standards, alternative to capita income. The four additional indicators that we use are daily calorie supply, daily protein supply, infant mortality rates, and life expectancy at birth. We present results obtained using three techniques previously considered in growth empirics. These are cross-country regressions, distributional dynamics, and cluster analysis. Our main finding is that convergence in real GDP per capita does not imply convergence in other social indicators. However, the qualitative results for all indicators are the same in the sense that the persistent gap between the rich and poor does not only manifest itself in real GDP per capita but also in living standards.     

Are Australia's tourism markets converging?

Many governments in low-income countries have promoted voluntary health insurance schemes in recent years, with the principal aim of improving access to services amongst those working in the informal economy. Few attempts to understand demand for such schemes exist, particularly in light of the importance of informal social security arrangements for many households. A model of demand for health insurance is developed reflecting this context, and estimated using data from Vietnam. The results show that informal financial networks may crowd out government promoted health insurance. Implications for theory and policy are discussed.     

Are BRICS exchange rates chaotic?

In this paper, we focus on the stochastic (chaotic) attributes of the US dollar-based exchange rates for Brazil, Russia, India, China and South Africa (BRICS) using a long-run monthly dataset covering 1812M01-2017M12, 1814M01-2017M12, 1822M07-2017M12, 1948M08-2017M12, and 1844M01-2017M12, respectively. For our purpose, we consider the Lyapunov exponents, robust to nonlinear and stochastic systems, in both full – samples and in rolling windows. For comparative purposes, we also evaluate a long-run dataset of a developed currency market, namely British pound over the period of 1791M01-2017M12. Our empirical findings detect chaotic behavior only episodically for all countries before the dissolution of the Bretton Woods system, with the exception of the Russian ruble. Overall, our findings suggest that the establishment of the free floating exchange rate system have altered the path of exchange rates removing chaotic dynamics from the phenomenon, and hence, the need for policymakers to intervene in the currency markets for the most important emerging market bloc, should be carefully examined.     

Are wages and productivity converging simultaneously in Euro-area countries?

A convergence analysis is applied to wages and productivity for Euro-area countries in the period from 1981 to 2001. The results show a reduction in the dispersion of wages and unit labour costs, but not in productivity. Different patterns are found for real and nominal wages: higher levels of inflation in countries with higher growth rates of unit labour costs have caused nominal wages to move towards equalization. Moreover, disparities in all the variables have remained more or less the same since 1997, suggesting that the establishment of a single currency area has not accelerated the process of wage equalization.     

Do overweight and obesity prevalence rates converge in Europe?

We exploit recently published data to evaluate the long-run evolution of overweight and obesity rates among European economies between 1975 and 2016. We find that overweight rates for both females and males converge in Europe. In particular, the convergence is driven by the nations in the EU. This fact is consistent with food patterns as well as trade, agricultural, and health policies that are common among EU members. Across our model specifications, the steady-state average overweight rate ranges between 60% and 77% for European female individuals and lies above 82% for their male counterparts. Confidence intervals suggest that such gender differences are statistically significant. In the EU, the point estimates of these rates are 62% and 91%, respectively. Obesity prevalence in Europe would reach long-term rates of 39% and 45% for females and males respectively, whereas these rates would be similar in the EU (approximately 28%).     

Are exchange rates interdependent? Evidence using wavelet analysis

We examine the co-movement in daily returns of USD–INR, EUR–INR, GBP–INR, and JPY–INR currency pair futures contracts traded on the National Stock Exchange of India (NSE) using the wavelet cohesion approach. This study contributes to the literature by examining the scantly studied area of co-movement in exchange rates and using the wavelet approach, which allows us to analyse time–frequency-wise co-movement of the time series. The empirical results indicate that the currency futures markets are nearly perfectly integrated in the long run (monthly, quarterly and biannual scales) offering little potential gains from international portfolio diversification. The discrepancies between currency futures markets are small and almost fade away within 3–6 months. Moreover, international currency diversification might offer relatively higher potential gains at intraweek, weekly, and fortnightly time horizons owing to lower correlations among the currencies under consideration. Finally, our multiple-wavelet correlation and cross-correlation analysis shows that GBP acts as a potential leader/follower across scales. The results of our analysis indicate the dynamic pattern of co-movement among the major currency futures contracts, which provides several implications for portfolio managers and international investors participating in the Indian market.     

Are US macroeconomic series difference stationary or trend-break stationary?

This article tests for the presence of a unit-root in all time series included in the extended Nelson–Plosser data set using the statistics devised by Zivot and Andrews, Perron and Murray and Zivot. It specifies the mixed model characterization of the trend-break stationary alternative that allows for a simultaneous break in both the intercept and slope of the trend-function. It rejects the unit-root null hypothesis for real GNP, nominal GNP, real per capita GNP, industrial production, employment, GNP deflator, nominal wages, interest rate and common stock prices. Use of appropriate critical values to assess the significance of the trend-function coefficients reveals that the slope-break should be included in real GNP, nominal GNP, real per capita GNP, nominal wages, interest rate and common stock prices. The results indicate that there is less evidence against the unit-root hypothesis with the extended Nelson–Plosser data compared to the original Nelson–Plosser data.     

Is income converging in China?

This study adopts a flexible Fourier unit‐root test proposed by Enders and Lee (2012) to revisit the tendency towards convergence in real per capita income among provinces after economic reform in China. When a data‐generating process is non‐linear, a Fourier series not only allows for the possibility of an unknown number of structural breaks with unknown forms but also allows for the use of a low‐frequency component to capture multiple changes. Contrary to what the linear statistics suggest, our results from a flexible unit‐root test indicate that China's eastern and western regions are converging to their own specific steady states.     

Are professional forecasts of growth in US business investment rational?

Utilizing comparable time-series forecasts as benchmarks, we document the “weak” and “stronger” rationality of professional forecasts of growth in business investment for 1982-2009. Consistent with these findings, the forecasts are directionally accurate and imply symmetric loss.     

Are state–local government expenditures converging? New evidence based on sequential unit root tests

Large and persistent gaps in subnational public expenditure have important implications regarding growth, equity, and migration. In this context, we revisit the question of expenditure convergence across the American states to provide more nuanced evidence than found by a small number of previous studies. We employ a methodology due to Smeekes (Bootstrap sequential tests to determine the stationary units in a panel, 2011) that sequentially tests for unit roots in pairwise (real per capita) expenditure gaps based on user specified fractions. In a panel of 48 combined state–local government units (1957–2008), we found that expenditures on highways, sanitation, utility, and education were far more convergent than expenditures on health and hospitals, police and fire protection, and public welfare. There was little evidence of “club convergence” based on the proportion of intraregional convergent pairs. Several historically high-grant receiving states showed relatively strong evidence of convergence. Our results bode well for future output convergence and opportunities for Tiebout-type migration across jurisdictions. They also imply a diminished role for public infrastructure and education spending in business location choices over time and a mixed role for federal grants in inducing convergence.     

Are there asymmetries in the response of bank interest rates to monetary shocks?

This article examines the velocity and asymmetry of the response of bank interest rates to monetary policy shocks. Using an asymmetric vector error correction model, it analyses the pass-through of changes in money market rates to retail bank interest rates in Italy in the period 1985–2002. The main results of the article are: (1) the speed of adjustment of bank interest rates to monetary policy changes increased significantly after the introduction of the 1993 Consolidated Law on Banking; (2) interest rate adjustment in response to positive and negative shocks is asymmetric in the short run, but not in the long run; (3) banks adjust their loan (deposit) rate faster during periods of monetary tightening (easing); (4) this asymmetry almost vanished since the 1990s.     

Does reputation enhance response rates?

Declining response rates and the potential for deterioration in the quality of survey data require reconsideration of the role of incentives to participate in interviews. This article argues that the strategies associated with linking public goods to private goods to establish reputation effects for the private goods involved can also be used to enhance confidence in the objectives of the request for an interview. In this literature, an assured reputation is established for those selling products by offering to contribute some of the proceeds of a sale to charity. The results of our field experiment indicate that combining charity with financial incentives appears to increase confidence in survey objectives for those familiar with the interview process.     

Are there bubbles in exchange rates? Some new evidence from G10 and emerging market economies

The existence, or otherwise, of bubbles has become a topical issue in economics and finance, particularly following the Global Financial Crisis. Using the generalized sup ADF (GSADF), unit root tests of Phillips et al. (2015a, PSY) we investigate evidence for exchange rate bubbles in some G10, Asian and BRICS countries from Mar.1991-Dec.2014. We conclude that the US$-Mexican Peso crisis of 1994–95 was a bubble. Of particular interest to financial market trading, is that newly emerging countries, with relatively shallow financial markets, may be more likely to exhibit bubbly behavior in foreign exchange markets than more mature G10 countries.     

How do banks set interest rates?

This paper studies cross-sectional differences in banks interest rates. It adds to the literature in two ways. First, it analyzes systematically the micro and macroeconomic factors that influence the price-setting behaviour of banks. Second, by using banks’ prices (rather than quantities) it provides an alternative way of disentangling loan supply from loan demand shift in the “bank lending channel” literature. The results suggest that heterogeneity in the banking rates pass-through - depending on liquidity, capitalization and relationship lending - exists only in the short run.     

Is eco-efficiency in greenhouse gas emissions converging among European Union countries?

Eco-efficiency refers to the ability to produce more goods and services with less impact on the environment and less consumption of natural resources. This issue has become a matter of concern that is receiving increasing attention from politicians, scientists and researchers. Furthermore, greenhouse gases emitted as a result of production processes have a marked impact on the environment and are also the foremost culprit of global warming and climate change. This paper assesses convergence in eco-efficiency in greenhouse gas emissions in the European Union. Eco-efficiency is assessed at both country and greenhouse-gas-specific levels using Data Envelopment Analysis techniques and directional distance functions, as recently proposed by Picazo-Tadeo et al. (Eur J Oper Res, 220:798–809, 2012). Convergence is then evaluated using the Phillips and Sul (Econometrica, 75:1771–1855, 2007) approach that allows testing for the existence of convergence groups. Although the results point to the existence of different convergence clubs depending on the specific pollutant considered, they signal the existence of at least four clear groups of countries. The first two groups are core European Union high-income countries (Benelux, Germany, Italy, Austria, the United Kingdom and Scandinavian countries). A third club is made up of peripheral countries (Spain, Ireland, Portugal and Greece) together with some Eastern countries (Latvia and Slovenia), while the remaining clubs consist of groups containing Eastern European countries.     

Are real exchange rates nonlinear with a unit root? Evidence on PPP for Italy: a note

In this article, we apply the recently developed threshold autoregression model to examine both linearity and stationarity of Italy's real exchange rate vis-à-vis her six trading partner (G6) countries. Our main finding is that Italy's real exchange rate is a nonlinear process that is not characterized by a unit root process for five of six trading partner countries. This provides strong support for purchasing power parity.     

Are voters rational?

We test whether a voter's decision to cast a vote depends on its probability of affecting the election outcome. Using exogenous variation arising at population cutoffs determining council sizes in Finnish municipal elections, we show that larger council size increases both pivotal probabilities and turnout. These effects are statistically significant, fairly large and robust. Finally, we use a novel instrumental variables design to show that the jumps in the pivotal probabilities are the likely candidate for explaining the increase in turnout, rather than the other observed simultaneous jumps at the council size cutoffs. Moreover, our results indicate that turnout responds only to within-party pivotal probabilities, perhaps because they are more salient to the voters than the between-party ones.     

Are Democracies Cleaner?

We inquire whether democracies enjoy lower pollution levels than autocracies by investigating the ‘clean democracy hypothesis’, which posits that democracies have a more demand-determined policy formation leading to more stringent environmental policies. We test this hypothesis with a large data set covering 137 countries and the period 1970–2012 using eleven different air pollutants as endogenous variables and a wide range of control variables measuring democracy, development stage, globalization, and factor endowments. We find no consistent evidence that democracies are cleaner, not even the richer ones, which casts doubt on the validity of single pollutants studies. Numerous checks show the robustness of our results.
