SME performance in transition economies: The financial regulation and firm-level corruption nexus

Using a general equilibrium endogenous growth model we explain underperformance in the small and medium enterprise sector as an effect of corruption and non-competitive banking. Limited competition in the banking sector causes a high loan-deposit spread, worsens the initial effect of corruption, and depresses growth. Fostering bank competition, for instance, by allowing foreign bank entry, would be a simple solution to this problem, but frequently, authorities choose to hamper bank competition. Therefore, we explain the persistence of non-competitive banking as a result of governments’ regulatory choice. If the government has a stake in the banking sector there exists a trade-off between current benefits from bank profits and future growth. Firm-level corruption affects intertemporal optimization and distorts the government’s choice towards more restrictive regulation, i.e., less bank competition, even if the deciding institution itself is not corrupt. These results show that the two prominent problems for small and medium enterprises, corruption and finance, are mutually reinforcing.     

Did foreign banks stay committed to emerging Europe during recent financial crises?

Our objective is to investigate empirically the behavior of foreign banks with respect to real loan growth during periods of financial crisis for a set of countries in which foreign banks dominate the banking sectors due primarily to having taken over large existing former state-owned banks. The eight countries are among the most developed in emerging Europe, their banking sectors having been modernized by the middle of the last decade. We consider a data period that includes an initial credit boom (2005 – 2007) followed by the global financial crisis (2008 & 2009) and the onset of the Eurozone crisis (2010). Our two innovations with respect to the existing literature on banking during the financial crisis are to separate foreign banks into two categories, namely, subsidiaries of the Big 6 European multinational banks (MNBs) and all other foreign-controlled banks, and to take account of the impact of exchange rates during the period. Our results show that bank lending was impacted adversely by both crises but that the two types of foreign banks behaved differently. The Big 6 banks remained committed to the region in that their lending behavior was not different from that of domestic banks supporting the notion that these countries are treated as a “second home market” by these European MNBs. Contrariwise, the other foreign banks active in the region were involved in fueling the credit boom but then decreased their lending aggressively during the crisis periods. Our results also indicate that bank behavior in countries having flexible exchange rate regimes differs from that in those in (or effectively in) the Eurozone. Our results suggest that both innovations matter for studying bank behavior during crisis periods in the region and, by extension, to other small countries in which banking sectors are dominated by foreign financial institutions having different business models.     

Growth Cycles and Market Crashes

Market booms are often followed by dramatic falls. To explain this requires an asymmetry in the underlying shocks. A straightforward model of technological progress generates asymmetries that are also the source of growth cycles. Assuming a representative consumer, we show that the stock market generally rises, punctuated by occasional dramatic falls. With high risk aversion, bad news causes dramatic increases in prices. Bad news does not correspond to a contraction of existing production possibilities, but to a slowdown in its expansion. This economy provides a model of endogenous growth cycles in which recoveries and recessions are dictated by the adoption of innovations.

Why do bank loans react with a delay to shifts in interest rates? A bank capital explanation

We advance an explanation for the delay in the response of the volume of bank loans to innovations in monetary policy. Capital requirements may effectively tie the evolution of bank credit to the evolution of bank equity. By uncovering a new mechanism by which shifts in interest rates affect the profitability of the banking sector, and in turn its equity, we find that the resulting movements in the amount of aggregate loans are consistent with the regularities observed in the data.     

银行业结构与经济增长

本文运用中国28个省区在1985—2002年间的面板数据,考察银行业结构对经济增长的影响。文章对银行业结构的分析着眼于不同规模的银行在银行体系中的相对重要性,度量指标为中小金融机构的市场份额,即四大国有商业银行之外的其他金融机构的贷款余额占各地区全部金融机构贷款余额的比例。为了克服银行业结构可能存在的内生性问题,文章用1994年启动的国有银行商业化改革的政策因素来构造银行业结构的工具变量。运用双向固定效应模型的估计结果显示,在中国现阶段,中小金融机构市场份额的上升对经济增长具有显著的正向影响。     

Complementarity and sequencing of innovations: new varieties and mechanized processing for cassava in West Africa

Complementarity among inter-related innovations may help explain the location and timing of productivity growth, and may be particularly important in the transformation of semi-subsistence agrarian economies. We study the case of cassava in West Africa, where both mechanized processors and new varieties are more widespread in Nigeria than in neighboring countries. One explanation involves complementarity: mechanization may have induced new variety adoption, or vice-versa. We test the magnitude and significance of these linkages using a system of equations approach. Controlling for other factors, we find that new variety adoption consistently increases the likelihood of subsequent mechanization by an average of 75 percent. Mechanization is less consistently associated with subsequent new variety adoption. Historically, mechanization came first – but the later development of new varieties made mechanization much more profitable, and the two then spread together.     

资本账户自由化、信贷扩张与系统性银行危机风险*

本文研究在资本账户自由化下，信贷扩张与资本流入对于系统性银行危机风险的影响。利用89个国家1973—2016年的长面板数据，并控制影响银行危机风险多项因素后，研究发现资本账户自由化有助于降低银行危机风险。进一步研究发现，FDI流入能显著降低银行危机风险；适量的股权投资流入有助于增强银行业稳定性；但当股权投资大量流入时，伴随着信贷过度扩张和资产泡沫，银行危机风险急剧增加；较低的债权投资流入对银行业稳定性无显著影响，但当超过一定规模时，银行危机风险显著增加。     

Inside Shadow Banking in China: Credit Driven Growth vs. Financial Stability

Shadow banking has been growing rapidly in China since the 2008 global financial crisis. Shadow banking has also played an increasing role in supplying credit. I investigate the development of the shadow banking sector, and assess its impacts on financial stability and economic growth in China. I argue that, due to the loose regulations and institutional characteristics of the shadow banks, these banks tend to adopt business practices that elevate institutional risks. At the systemic level, shadow banks have contributed to credit expansion and credit-driven growth. However, such growth entails significant financial risks and renders the macro-economy financially fragile. I conclude with a discussion of imminent fullblown financial crisis, calling for policy actions.     

The effect of financial liberalization on banking sector stability

Several studies indicate that financial liberalization increases likelihood of a financial crisis without distinguishing between a normal period, unstable period preceding the onset of banking panics and crisis/post period. We explain in this paper the relationship between financial liberalization and banking sector vulnerability. Then, we argue that banking sector turmoil is most likely to occur after an intermediate degree of liberalization. Using a recently updated dataset for financial reforms, we find an inverted U-shaped relationship between liberalization and the likelihood of banking crisis for a sample of 49 countries between 1980 and 2010. We used a multinomial logit model in order to take into account what is called the ‘post crisis bias’. We ask whether the relationship remains when institutional characteristics of countries and dynamic effects of liberalization are considered. The empirical results indicate that the relationship between liberalization and banking sector stability depends strongly on the strength of capital regulation and supervision. With very weak regulation and supervision, the probability of banking crises is increasing with liberalization but this relationship is reversed as regulation and supervision become significant. The most important type of liberalization in relation to banking crises seems to be operational. A policy implication is that positive growth effects of liberalization can be achieved without increasing the risk of a banking fragility if appropriate institutions are developed.

The welfare cost of banking regulation

The Basel Accords promote the adoption of capital adequacy requirements to increase the banking sector's stability. Unfortunately, this type of regulation can hamper economic growth by shifting banks' portfolios from more productive, risky investment projects toward less productive but safer projects. This paper introduces banking regulation in an overlapping-generations model and studies how it affects economic growth, banking sector stability, and welfare. In this model, a banking crisis is initiated by an aggregated shock (in the risky sector) in a banking system with implicit bailout, and banking regulation is modeled as a constraint on the maximal share of banks' portfolios that can be allocated to risky assets. This model allows us to evaluate quantitatively the key trade-off, inherent in this type of regulation, between ensuring banking stability and fostering economic growth. The model implies an optimal level of regulation that prevents crises but at the same time is detrimental to growth. We find that the overall effect of optimal regulation on social welfare is positive when productivity shocks are sufficiently high (for example, in the subprime banking crisis episode) and economic agents are sufficiently risk-averse. Finally, we find that there is a trade-off between regulating the economy upfront (i.e. before the shock) and facing the challenge of making a huge bailout after the crisis.     

县域视角下的贫困、金融发展与经济增长*——基于系统GMM方法的再检验

本文以内生区域金融发展理论为基础构建动态面板模型,同时引入贫困因素进一步识别区域金融与经济的非线性关系,将实证对象细化到县域层面,运用系统GMM方法检验贫困与非贫困县域金融对经济增长影响的差异。本文研究发现,信贷层面上的金融发展对经济增长的推动效应普遍存在,而储蓄层面金融发展的效应则存在地区差异,非贫困县的储蓄与经济无关,贫困县的储蓄与经济增长负相关。因此本文指出,区域信贷配给和区域信贷创造理论更适于解释贫困地区的金融发展问题,贫困县域储蓄的负效应是本地储蓄外流和转化效率低下的结果,与我国银行业跨     

Economic reforms,efficiency and productivity in Chinese banking

This paper analyzes the impact of banking reforms on efficiency and total factor productivity (TFP) change in Chinese banking industry. Using an input distance function, we find that joint-equity banks are more efficient than wholly state-owned banks (WSOBs). Furthermore, both WSOBs and joint-equity banks are found to be operating slightly below their optimal size, suggesting potential advantages in expansion of their businesses. Overall, TFP growth was 4.4% per annum for the sample period 1993–2002. Joint-equity banks experienced much higher growth in TFP (5.5% per annum) compared to the WSOBs (1.4% per annum).      

ON THE ESSENTIALITY OF BANKS*

We compare allocations sustained by credit with allocations sustained by bank notes (inside money) in a search model with decentralized trade and limited monitoring. We demonstrate that there exists a credit arrangement that is superior to inside money. However, in contrast with inside money, this arrangement is not robust to an expansion of trade that is not accompanied by an adequate increase in the degree of monitoring. Therefore, banks are essential when trade is intense and monitoring is limited. As a historical application, we argue that our model helps explain the origins of banking in Medieval and Early Modern Europe.     

Financial development and openness: Evidence from panel data

This paper addresses the empirical question of whether trade and financial openness can help explain the recent pace in financial development, as well as its variation across countries in recent years. Utilising annual data from developing and industrialised countries and dynamic panel estimation techniques, we provide evidence which suggests that both types of openness are statistically significant determinants of banking sector development. Our findings reveal that the marginal effects of trade (financial) openness are negatively related to the degree of financial (trade) openness, indicating that relatively closed economies stand to benefit most from opening up their trade and/or capital accounts. Although these economies may be able to accomplish more by taking steps to open both their trade and capital accounts, opening up one without the other could still generate gains in terms of banking sector development. Thus, our findings provide only partial support to the well known Rajan and Zingales hypothesis, which stipulates that both types of openness are necessary for financial development to take place.     

Re-examining the financial development and economic growth nexus in Kenya

This paper re-examines the causal relationship between financial development and economic growth in Kenya for the period 1966–2005 within a quadvariate vector autoregressive (VAR) framework by including exports and imports as additional variables to the finance–economic growth nexus. We use four conventionally accepted proxies for financial development, namely money supply (M2), liquid liabilities (M3), domestic bank credit to the private sector and total domestic credit provided by the banking sector (all percent of GDP). Applying a modified version of the Granger causality test due to Toda and Yamamoto [Toda, H.Y. and Yamamoto, T., Statistical inference in vector autoregressions with possibly integrated process. Journal of Econometrics 1995; 66; 225–250], our empirical results suggest that in three out of the four measures of financial development we found evidence of a two-way Granger causality: (1) between domestic credit provided by the banking sector and economic growth; (2) between total domestic credit provided by the banking sector and economic growth, and (3) between liquid liabilities and economic growth. This implies that neither the supply-leading nor the demand-following hypotheses are supported in Kenya and that economic growth and financial development are jointly determined, or they complement each other. A major implication of our finding is that financial development promotes economic growth in Kenya and that policies at enhancing the development of the financial sector can help to spur economic growth.     

Does the Degree of Development Matter in the Impact of Banking Crises on International Trade?

This paper analyzes how a country's degree of economic development affects the impact of banking crises on international trade. To this end, we estimate a gravity model of trade using a sample of 139 countries over the period 1975–2012. Our results show that middle income countries are generally the most negatively affected. In contrast, financial turmoil appears to have less impact on bilateral trade flows among high income countries and, more specially, among low income nations. The level of financial development, contract enforcement, as well as the extent of the use of banking credit within international trade all help to explain our findings.     

Financing Channels and Monetary Policy in a Dual Banking System: Evidence from Islamic Banks in Indonesia

Using Indonesian Islamic banking data from 2003 to 2014, this article employs a panel regression methodology to investigate the responses of Islamic banks to changes in financing rates and monetary policy, which may differ depending on their characteristics. The results suggest that the financing rate has a negative impact on financing at Islamic banks, while bank‐specific characteristics have a positive influence on it. The size and amount of capital have a greater impact than liquidity on financing at Islamic banks. However, changes in monetary policy are insignificant on bank financing, which implies that the transmission of monetary policy through the Islamic segment of the banking sector is weak. Furthermore, the weak impact of monetary policy on bank financing can be explained by the dramatic expansion of Islamic banks during the sample period, which contributed to a substantial increase in deposit growth and a high liquidity position.     

Telecommunications, an instrument of radical change for both the 20th and 21st centuries

This paper compares and contrasts how entrepreneurial disruptions, firm innovations, foreign market expansion and government restraint interact during three distinct periods to create and dramatically expand one service—telecommunications. Because this service has the ability to help business overcome the frictions of time, it has become both an enabling and lead technology in the dramatic economic growth. Telecommunications was instrumental in ushering in the formation of the third Kondratieff long Wave upswing at the beginning of the 20th century and appears to be important in jumpstarting the emerging information economy in the fifth Kondratieff Wave at the end of the 20th century.
