Revisiting the safe haven role of Gold across time and frequencies during the COVID-19 pandemic

This research empirically evaluates the potential diversification benefits of Gold during the COVID-19 pandemic period, when including it in equity-based asset allocation strategies. This study proposes minimum VaR portfolios, with monthly rebalance and different wavelet scales (short-run, mid-run and long-run), doing both an in-sample and out-of-sample analysis. We find much more unstable weights as the frequency of the decomposition becomes lower, and strong evidence of the outperformance of the mid-run decompositions over the rest of active management strategies and the passive management of buy and hold the variety of single equity indices. Thus, we may shed some light on the role of Gold as a safe haven when properly filtering aggregated data.     

The effect of stabilization fund to rescue stock market based on expected return-capita circulation equation

This paper builds an expected return-capital circulation equation to explore the impact of using the stabilization fund to rescue the stock market when it crashes. We find that the stock stabilization fund buying the underlying stocks can restrain the sharp decline of the stock index, but it is also easy to promote the fluctuation in prices of small-cap stocks. Therefore, we suggest that the government in use of stock stabilization fund to take control of the stock market crash should not only buy underlying stocks in the index but also pay attention to prevent implicit stock disaster in the market.     

The macroeconomic impact of economic uncertainty and financial shocks under low and high financial stress

External financial frictions might increase the severity of economic uncertainty shocks. We analyze the impact of aggregate uncertainty and financial condition shocks using a threshold vector autoregressive (TVAR) model with stochastic volatility during distinct US financial stress regimes. We further examine the international spillover of the US financial shock. Our results show that the peak contraction in euro area industrial production due to uncertainty shocks during a financial crisis is nearly-four times larger than the peak contraction during normal times. The US financial shocks have an influential asymmetric spillover effect on the euro area. Furthermore, the estimates reveal that the European Central Bank (ECB) is more cautious in implementing a monetary policy against uncertainty shocks while adopting hawkish monetary policies against financial shocks. In contrast, the Fed adopts a more hawkish monetary policy during heightened uncertainty, whereas it acts more steadily when financial stress rises in the economy.     

E-commerce in Spain: Determining factors and the importance of the e-trust

This paper identifies and estimates the determinants for participating in e-commerce and developing e-trust, as well as the importance of e-trust for e-commerce in Spain. For its analysis, a national survey from 2014 to 2019 is used and the logit model is implemented. It is concluded that the e-trust is a determining factor in e-commerce, and the improvement of equality education helps the growth of online commerce and e-trust. In turn, e-trust encourages the use of all digital resources.     

Branch network structure,authority and lending behaviour

Using a novel dataset of Ukrainian banks, this paper examines the link between the structure of branch network and bank lending. Bank regional branches are categorised into contact points without loan decision-making authority and more independent delegated branches which can make loan decisions. We find that a large and dispersed network of contact points can help increase credit supply and mitigate risks through diversification. Further, banks benefit from the information advantage brought by the presence of delegated branches in local markets. However, the longer distance between headquarters and local delegated branches, the more amplified agency problems become, which outweighs the benefits. Our findings suggest that the optimal structure could be a centralised network of delegated branches combined with a diversified access point network.     

COVID-19 crisis and the efficiency of Indian banks: Have they weathered the storm?

The purpose of this study is to determine whether Indian banks were able to weather the COVID-19 storm. We estimate banks’ deposits-generating and operating efficiencies using a two-stage directional distance function-based network data envelopment analysis (DDF-NDEA) approach and seek to capture the immediate impact of COVID-19 on these efficiency measures by comparing their magnitudes in the pre-pandemic (2014/15–2019/20), just 1-year prior to the pandemic (2019/20), and during the pandemic year (2020/21) periods. The study looks at whether the impact of the COVID-19 pandemic was uniform across ownership types and size classes. The empirical findings suggest that the Indian banking system was resilient and withstood the immediate impact of the COVID-19 pandemic. During the study period, however, the large and medium-sized banks experienced some efficiency losses. By and large, regardless of bank group, banks have shown resilience to the shock of the global health pandemic and improvements in efficiency.     

Sectoral credit reallocation: An excessive bank risk-taking explanation

This paper develops a theoretical model to provide an alternative explanation for the credit to nontradable sector growing faster than credit to tradable sector, after a US expansionary monetary policy, based on an excessive risk-taking channel. This is, a reduced foreign interest rate decreases bank default probability, which in turn diminishes banks’ incentives to take excessive risk. This produces a reallocation of loan supply to nontradable sector since tradable loans are riskier. Using monthly sectoral credit data at the bank level for the Peruvian economy in the 2004–2019 period, we find evidence of the excessive bank risk-taking channel on sectoral credit reallocation.
