© 2020 Elsevier B.V. A credit guarantee scheme is a method for promoting lending to small and medium-sized enterprises (SMEs) by formal financial institutions. It reduces information asymmetry and SMEs’ collateral burden, but at a cost of a credit guarantee fee. The paper provides a theoretical model for calculating the optimal credit guarantee fee. In the empirical part, this study examines whether selected macroeconomic variables and financial health of SMEs have a statistically significant impact on default risk ratio of loans to SMEs – the main determinant of the fee. Principle component analysis (PCA) and two vector error correction model (VECM) models are applied on a sample of 1363 SMEs. Empirical results support our hypothesis that the credit guarantee fee should be different for sound and risky SMEs in order to avoid moral hazard, but also according to the macroeconomic state.

© 2020 Elsevier B.V. This paper analyzes a unique case of default risks associated with a solar homes program in Bangladesh, implemented by the Infrastructure Development Company Limited (IDCOL). Out of 4.3 million solar homes adopter households, about 1.2 million households became default in paying their due payment of the solar home system. We explain the behavior of the customers in a hyperbolic discounting framework where various shocks increase the risks of default. Further we extend the model to explain moral hazard problem under the refinancing program structure in the absence of an optimal contract. For empirical analysis, we apply the Cox's proportional hazard model to study the factors responsible for default and instantaneous hazard rates. Using primary survey data from 1300 households, we find that various exogenous shocks and financial constraints can explain the default situation of the customers along with a portion of the default customers being adversely selected in the context of moral hazard problem, which is consistent with the prediction of our theoretical model. We propose a market-based solution to the problem by withdrawing subsidies from the program.

© 2020 The Covid-19 pandemic and global economic recession has shrunk global energy demand and collapsed fossil fuel prices. Therefore, renewable energy projects are losing their competitiveness. This endangers the achievement of several Sustainable Development Goals (SDGs) and the Paris Agreement on Climate Change. Various consulting companies define the SDGs differently. Institutional investors hire consulting companies and allocate their investment based on the consultants’ suggestions. This paper theoretically shows that the current allocation of investors by considering SDG based on various consulting companies will lead to distortion in the investment portfolio. The desired portfolio allocation can be achieved by taxing pollution and waste such as CO2, NOx, and plastics, globally with the same tax rate. Global taxation on pollution will lead to the desired portfolio allocation of assets.

International remittances by immigrants to their home countries is key in the funding development in migrant-sending countries. This study investigates the combined impact of international remittance inflows and financial inclusion on economic growth using a sample of 60 low- and middle-income countries over 1996–2017. The study constructs a composite financial inclusion index using principal component analysis. The results show that financial inclusion could strengthen the growth-enhancing effect of remittances. Thus, the study helps explain the development dilemma of remittance inflows and financial inclusion in migrant-sending countries to boost their economic growth.

This article examines the current portfolio allocation in ESG and Green projects. Traditional investments focus on rates of return and risks associated with investment. Environmental, Social and Governance (ESG) or Green factors are additional components that investors have to pay attention to. Environmental protection is very important. However, we see that the current different definitions of ESG or Green factors lead to distorted allocations in portfolio investments. In order to bring portfolio allocations to a desirable direction, global taxation on pollution or creation of an accurate Green credit rating based on emissions of various pollutants are recommended.

The main objective of the Bank of Japan's monetary policy is inflation targeting; however, it may be associated with the recently increased income disparity in Japan. Using the autoregressive distributed lag (ARDL) estimation model, this study conducted in the context of an aging society revealed that the bank's monetary policy increased income inequality through increased financial asset prices, resulting in a widening of the income gap. We also find that in the long run, the aging population will increase income disparity in Japan; however, tax policy will partially mitigate the adverse effect on income inequality. Unconventional monetary policy will not bring a desirable result for the Japanese economy and the nation as a whole. In addition, the government needs to revise the incremental tax system so that wealthier groups pay more tax than before. In addition, expanding the tax system by adopting the carbon taxation scheme would be beneficial. The government with this kind of tax can pursue two major goals: reducing poverty and environmental pollution, which are ongoing challenges in Japan.

The goal of our study is to examine the impact of natural disasters on the South Pacific Stock Exchange. We use daily time-series data for Fiji's stock market for the period 2000-2019. Our empirical framework is based on three factor regression models, namely the market model, the Fama and French three-factor model, and the Fama and French five-factor model. We find evidence that natural disasters in Fiji reduce abnormal returns in the most relevant five-factor model. Additionally, we provide evidence that different types of natural disasters have heterogeneous effects on Fiji's stock market. Our findings are further supported by a robustness check.

Hong Kong's housing market witnessed a dramatic housing price appreciation in recent years, with the price index for private domestic housing units being three times higher than ten years ago. This trend is supported by both internal and external factors, as illustrated in this paper. By developing a theoretical model and an empirical analysis on the key variables influencing housing prices using monthly data from 1999 to 2018, we find that the main drivers of housing price appreciation are from the demand side and include income level, money supply and inflation. The main contribution of this study is the quantification of the role of Mainland China's macroeconomic factors in housing price booms in Hong Kong. Our study shows that capital inflow from and inflation and recessions in Mainland China contribute to increasing housing prices in Hong Kong because the city's real estate is seen as a way to preserve asset value. These findings call for the need for control of capital inflow between the two economies as well as for stricter regulations against empty houses in Hong Kong.

Japan economy is dominated by Small and Medium enterprises. It covers around 99.7% of all enterprises operated in Japan and employs around 70% of the working population and account for a large portion of economic output. But, like other SMEs in the world, they also the ones that have hardly hit by COVID-19 quarantine and business closures. Japanese government made emergency loans and credit guarantee to assist SMEs. However, moral hazard problems of banks and SMEs have to be remedied. In the capital market, many investors take risk-averse behavior to anticipate further measures. Infrastructure investments are most needed in Asian region yet finance for infrastructure investments would face with shortage of funds due to low rate of return and risks. Private financing by long term investors such as pension funds and insurance better be directed to support infrastructure investment. Spillover tax revenues could be partly directed to increase the rate of return. The Japanese economy faces with aging population which would widen fiscal deficits unless postponement of retirement age and productivity-based wage rate rather than seniority wage rate facing with this crisis. Therefore, Japan government need to look into innovative policies options for sustainable economic growth.

Determinants of international remittance inflow in Asia-Pacific middle-income countries

The international remittances by immigrants to their home countries is one of the key sources of funding development in middle-income countries, especially in migrant-sending countries. This study assesses the determinants of international remittances using panel data from 22 Asia-Pacific middle-income countries, most of which are well-known migrant-sending countries, using the generalized method of moments (GMM) method. The results show that the gap in the per capita GDP growth rate between origin and destination countries, gross enrollment ratio of secondary education, and trade openness are positively associated with remittance inflow. On the other hand, net foreign direct investment (FDI) inflows are negatively correlated with remittance inflows. The results of this study can be interpreted as a paradigm shift for acquiring foreign capital in middle-income countries, from remittances in earlier stages of development to more FDI inflows when the country has the pre-requisites for absorbing foreign capital. The remittance inflows should be highly important, especially in the early stage of economic development, as additional incomes, or investment sources for those who live in middle-income countries.

This paper assesses the effects of the most recent monetary policy behaviour of the Bank of Japan (in particular, zero interest rate policy and negative interest rate policy) and Japanese tax policy on income inequality in this country during the period of 2002Q1 to 2017Q3. The vector error correction model (VECM) that develops in this research shows that increase in money stock (m1) through Quantitative Easing (QE) and Quantitative and Qualitative Easing (QQE) policies of the BOJ significantly increases the income inequality. On the contrary, Japanese tax policy was effective in reducing the income inequality. Variance decomposition results show that increasing of income inequality by monetary policy is larger when comparing to decreasing effects of tax policy on income inequality. Cointegration and VECM results show that monetary policy has both short-run and long-run impacts but for tax policy paper could not find any significant short-run impact on income inequality. In addition, paper found that technological progress only in long-run can reduce the income inequality by increasing the marginal productivity of labour with positive impacts on employment and wages.

Enhancing Financial Connectivity Between Asia and Europe: Implications for Infrastructure Convergence Between the Two Regions*

This paper explores the methods and policies that could enhance the financial connectivity between Europe and Asia in infrastructure investments. We argue that if Asian governments agree to enter into a long-term repayment commitment with a share of spillover tax revenues of public infrastructure projects under a regulatory framework, it could attract European long-term institutional funds in Asia’s infrastructure projects. This approach will reduce divergence in infrastructure between the two regions and encourage regional connectivity. With some empirical evidence, this paper highlights the operational risks and methods of sharing spillover revenue for infrastructure projects.
