How efficient is the banking system of Asia’s next economic dragon? Evidence from rolling DEA windows

Vietnam is now widely regarded as a rising economic star and the next economic dragon of Asia. Its banking system has played a key role in this stellar economic performance. Since 1990, Vietnam’s banking system has undergone significant changes which saw its composition transformed from being state banks only to now being both state as well as private banks, and has performed generally well in terms of growth, profitability and stability. But is it efficient? We conduct a dynamic analysis of the level and trend of the cost and profit efficiency of the Vietnamese banking sector over the period 1995 to 2011 taking into account the Asian and Global Financial crises. We use the Data Envelopment Analysis (DEA) Windows Analysis approach and adjust for bank size in calculating the average efficiency score of the banking system. Our empirical findings show that the cost and profit efficiency of the Vietnamese banking system averaged around 0.90 and 0.75, respectively, with the state banks being more efficient than the private banks and with efficiency experiencing an upward trend over the analysis period. Moreover, we find that the Global Financial Crisis (GFC) and Asian Financial Crisis (AFC) did not significantly affect the efficiency of the whole Vietnamese banking system.     

Does asymmetric information matter in the early insurance market? Evidence from the auto insurance market

In the late 1960s, the performance of automobile insurance declined dramatically in Japan in spite of rapid growth in the diffusion rate, and the premiums were sharply raised several times in order to improve the situation. This observation indicates the possible presence of adverse selection (death spiral), and provides an ideal situation for assessing informational asymmetry. Using bodily injury liability (BIL) insurance data from 46 Japanese prefectures over the period 1966 to 1975, this article tests two hypotheses of adverse selection: (i) high-risk drivers were more likely to join the BIL insurance market and (ii) sharp premium increases drove low-risk policyholders away. Various empirical analyses show that there is little evidence for either type of adverse selection. We also test whether a risk-misperception hypothesis can explain our results, and find some evidence that the population density have a significantly positive impact on the demand for BIL insurance.     

How do the media scrutinise central banking? Evidence from the Bank of England

Central bank independence has raised questions of accountability ever since its global diffusion in the 1990s, and especially since the financial crisis. Yet, whilst the literature on central banks’ legislative oversight has expanded, the role of the media as account holders has been left largely unexplored. We assess media scrutiny by using an original dataset of news articles about the Bank of England published between 1997 and 2020, and by analysing the relationship between central banking outcomes and scrutiny in the form of evaluative and negative coverage of the Bank. We find that the variation in such coverage can be traced back to policy outcomes, but the association is largely confined to the post-crisis period. The findings support a view of the media as instrumental in central bank oversight, but also show the limits of this form of accountability.     

Does the banking sector structure matter for credit procyclicality?

The aim of this paper is to investigate whether the banking sector structure matters in explaining credit procyclicality for 17 OECD countries over the 1986–2010 period. To this end, we first provide a detailed classification of the banking system structure through the use of a hierarchical clustering methodology. Relying on the estimation of panel VAR models and accounting for potential heterogeneity between countries, we then propose a measure of credit procyclicality based on the impulse-response function of credit to a shock in GDP. Our findings show that while credit significantly responds to shocks in GDP, the structure of the banking sector is not a key factor in assessing the procyclicality of credit for OECD countries.     

Do banking system transparency and competition affect nonperforming loans in the Chinese banking sector?

The increasing importance of transparency practices and the improving status of bank competition in China are rarely explored in nonperforming loans (NPLs) literature. Thus, the purpose of this study is to examine banking system transparency and competition along with macroeconomic and bank-specific variables as determinants of NPL. We use the two-step system GMM dynamic panel model for Chinese banks based on annual data from 2000 to 2014. Our results indicate that high transparency in the Chinese banking system decreases poor-quality assets but not in the case of government-owned banks, whereas increase in competition increases NPL. Moreover, we find mixed results in the context of macroeconomics and bank-specific variables. Our study has practical implications in risk management practices and macro prudential policies.     

Does price dispersion increase with quality? Evidence from the online diamond market

This article empirically investigates the relationship between price dispersion and price level. Searches seem more valuable for products of high quality, but buyers may have little incentive to search since such products are less frequently purchased. The extent of price dispersion is examined using a sample of around 160 000 diamonds offered for sale online. Estimates from a two-stage econometric strategy show that price dispersion increases significantly with quality. An explanation is that buyers of high-quality gemstones pay little attention to the price of these diamonds and even more so if they perceive high prices as signals of quality and rarity of the diamonds they intend to purchase.     

Is the median voter decisive? Evidence from referenda voting patterns

This paper examines whether the voter with the median income is decisive in local spending decisions. Previous tests have relied on cross-sectional data while we make use of a pair of California referenda to estimate a first difference specification. The referenda proposed to lower the required vote share for passing local educational bonding initiatives from 67 to 50% and 67 to 55%, respectively. We find that voters rationally consider future public service decisions when deciding how to vote on voting rules. However, the empirical evidence strongly suggests that an income percentile below the median is decisive for majority voting rules, especially in communities that have a large share of high-income voters with attributes that suggest low demand for public services. Based on a model that explicitly recognizes that each community contains voters with both high and low demand for public school spending, we also find that an increase in the share of low demand voters is associated with a lower decisive voter income percentile for the high demand group. This two type model implies that our low demand types (individuals over age 45 with no children) have demands that are 45% lower than other voters. Collectively, these findings are consistent with high-income voters with weak preferences for public educational services voting with the poor against increases in public spending on education.     

Is market liquidity less resilient after the financial crisis? Evidence for US Treasuries

Understanding market liquidity resilience, i.e. the capacity of liquidity to absorb shocks, of United States Treasuries is crucial from a financial stability standpoint. The conventional resilience measure has limitations due to the use of the liquidity level. We propose a new complementary approach to analyze resilience based on liquidity volatility. For this purpose, we focus on the link between returns volatility and liquidity volatility, which is a relatively unexplored field. We fit a bivariate conditional correlation (CC-) GARCH model for the 10-year bond returns and five liquidity indicators from January 2003 to June 2016 to analyze persistence and spillovers between these variables in a parsimonious way. We find that after the crisis, spillovers between liquidity volatility and returns volatility are higher, feedback loops are more likely and volatility persistence is lower, which is consistent with a lower resilience. Our results help to explain recent episodes of high volatility in this market.     

Are momentum crashes pervasive regardless of strategy? Evidence from the foreign exchange market

This article studies the option-like behaviour of popular momentum strategies implemented in foreign exchange markets. The results confirm recent research findings of strong option-like behaviour for momenutm measures, based on the cumulative return from 12 and 6 months prior to the formation date Surprisingly, there is no such evidence for the popular momentum strategy accounting for a 1-month formation period.     

Is productivity diverging in the EU? Evidence from 11 Member States

An argument that received a lot of attention in the political and economic discussion surrounding the recent crisis in the EU is that diverging trends in productivity across member countries will undermine the viability of the common currency. This article examines the issue of convergence in multifactor productivity using sector-level data from 11 EU Member States. A state-space model is developed, and formal Bayesian model comparisons are performed to infer whether productivity is diverging, both at the aggregate level and at a sector-by-sector basis. The data point toward diverging productivity at the aggregate level, but suggest the opposite for many individual sectors.     

Is the slope of the Phillips curve time-varying? Evidence from unobserved components models

This paper formally tests for time variation in the slope of the Phillips curve using a variety of measures of inflation expectations and real economic slack. We find that time variation in the slope of the Phillips curve depends on the measure of inflation expectations rather than the measure of real economic slack. We find strong evidence in support of the time-varying slopes of the Phillips curve with different measures of inflation expectations. Thus, we conclude that the slope of the Phillips curve is time-varying.     

Does reference point matter in the leverage–return relationship? Evidence from the US stock market

The leverage–return relationship is supported by inconclusive empirical evidence in terms of its sign and significance. In this study, we argue that such a puzzling relationship can be understood by extending the traditional theoretical framework in a way that captures the reference dependence characteristics of prospect theory. We postulate that a firm’s leverage position relative to its reference point (i.e. target leverage) combined with market conditions places firms in either a gain or a loss domain, thereby resulting in different leverage–return relationships. Leverage and expected equity returns generally exhibit positive and negative relationships in gain and loss domains, respectively. Three hypotheses are derived and tested using 1998–2013 empirical data from the US stock market. This article contributes to the existing literature by confirming the applicability of prospect theory in explaining expected returns in the stock market.     

How competitive is the Syrian banking sector? Empirical evidence from ‘pre/post’ war Syria

This paper investigates the degree of market power in the Syrian banking sector over the period 2005–2016 where research on competitive conditions does not exist. The degree of competitiveness is assessed based on the revenue elasticity to input prices approach and is related to a set of market indicators. To test whether the Syrian crisis has altered the competitive conditions over the years of the sample, I divide the full sample into two subsamples, namely the pre-crisis years (2005–2012) and the crisis years (2013–2016). The results suggest that banks in Syria earn their interest and total revenue under conditions of monopoly. I find that the trend of market structure—characterized by a monopoly—in the pre-crisis years continues over crisis years. My findings provide robust evidence that a collusive behaviour among banks is in operation in the banking sector of Syria. The difficult penetration into/exit from the market has led to the existence of a profit-curb mechanism for the Syrian banks, hence, an upward shift in the marginal cost curve will be associated with a reduction in revenue as a result of the optimal condition for these banks which act as monopolists.     

Is the US Phillips curve stable? Evidence from Bayesian vector autoregressions*

It has been claimed that the fall in US inflation during the Great Recession was surprisingly small. One possible explanation for this is that the Phillips curve is unstable and that its slope was lower around the Great Recession. We investigate the importance of time-varying parameters using Bayesian vector autoregressions for inflation and unemployment. We find support for time variation in the inflation equation and an unstable Phillips curve that was somewhat flatter between 2005 and 2013. However, conditional forecasts mostly suggest that inflation was not unexpectedly high around the Great Recession, which puts the claim of a “missing disinflation” into question.     

Does foreign technology transfer spur domestic innovation? Evidence from the high-speed rail sector in China

This paper investigates the introduction of high-speed railway (HSR) technology into China to study the local impacts of foreign technology transfer. The large-scale technology transfer project, covering specific technological categories and directly benefiting railway-related firms in various cities, enables us to describe how foreign technology is digested and spurs follow-up innovation in firms apart from directly receiving ones. We find that technology transfer generates significant localized spillovers to nearby firms not only in terms of more patents, but also as higher productivity and revenue growth. Moreover, technological similarity, rather than input-output linkages, plays a dominant role in explaining the knowledge spillover both at the firm level and the aggregate level, which indicates the importance of absorptive capacity in digesting foreign technologies. Overall, our paper sheds new light on the innovation policy of developing countries as well as the global business strategy of multinational corporations (MNCs).     

Democratization and the depoliticization of the banking sector: Are all banks affected equally?

This paper shows that the influence of the dramatic change in political ties of the Indonesian banking sector following democratization varies widely by bank ownership type. Panel estimates using several unique data-sets show that the decrease in political ties over democratization positively influences the performance of government-owned banks while negatively influencing the performance for privately held banks. Results remain robust to a variety of alternative hypotheses and sensitivity tests. This study provides evidence not only of the differential impact of depoliticization, but also suggests that the relationship between political connections and performance may be different based on bank ownership.     

Is there a quality bias in the Canadian CPI? Evidence from microdata

Rising consumer prices may reflect shifts by consumers to new higher‐priced products, mostly for durable and semi‐durable goods. I apply Bils’ (2009) methodology to newly available Canadian consumer price data for non‐shelter goods and services to estimate how price increases can be divided between quality growth and price inflation. I find that less than one third of observed price increases during model changeovers should be attributed to quality growth. This implies overall price inflation close to inflation measured by the official index. I conclude that, according to Bils’ methodology, the quality bias is not an important source of potential mismeasurement of CPI inflation in Canada.     

Is assortative matching efficient?

Summary. This paper develops some general conditions under which complementarities between individual agents imply that assortative matching is efficient. Our analysis has four main findings. First, when agents are organized into equal-sized groups, just as in Becker (1973), the presence of within-group complementarities is sufficient for stratification to be efficient. Second, if group sizes vary, assortative matching may not be efficient even though complementarities are present, unless particular functional form assumptions are imposed. Third, the connection between assortative matching, complementarities and efficiency reemerges if one considers sequences of replications of the economy in which individual coalitions are uniformly bounded in size. Fourth, the presence of feedbacks from the composition of group memberships has important effects on efficient allocations and breaks any simple link between assortative matching and efficiency. Together, these results suggest that the characterization of the cross-section evolution of an efficiently sorted economy is likely to be highly complex.

Does religious faith affect household financial market participation? Evidence from China

Based on the 2013 China Household Finance Survey data, this paper investigates the impact of religious faith on household financial market participation and portfolio choice. The results show that religious faith can significantly promote household financial market participation. Besides, religious faith can increase the proportion of risky assets held by households, including equities. We also find that the need for social interaction and human capital accumulation can significantly induce religious residents to participate in financial markets and hold risky assets. Overall, our results reveal how faith affects household finance activities in China.
