Economic growth in South-eastern Europe: the role of the banking sector

This article analyses the relationship between banking sector efficiency and economic growth using a panel data analysis of six South-eastern European countries during the period 1995–2005. The analysis is concentrated on the banking sector because other segments of the financial market are underdeveloped in our sample of countries. We measure the qualitative development in the banking sectors by using the margin between lending and deposit interest rates as well as the share of non-performing loans. By applying the panel data method in a growth-type equation setting, we confirm that improvements in banking sector efficiency, measured through the decreasing interest rate spread, exerted a positive influence on the growth rate of the countries in the region.     

The political economy of the G20 agenda on financial regulation

The paper empirically examines the implementation record of international financial regulation of the banking sector. The study finds that the size of the banking sector and the presence of global systemically important banks (G-SIBs) are positively associated with a stronger implementation record. These results suggest that cooperative motives of internalising externalities, creating a level playing field and preserving financial stability play a role in explaining the implementation record. We find evidence that this cooperative behaviour may be driven by the self-interest of global players as the positive record is particularly strong in countries where large banking sectors and big banks are both present, and where regulation only applies to large players. Sectoral concentration, bank health and the share of foreign ownership yield more mixed results as regards their impact on implementation.     

The sources of contagion risk in a banking sector with foreign ownership

Foreign-dominated banking sectors, such as those prevalent in Central and Eastern Europe, are susceptible to two major sources of systemic risk: (i) linkages between local banks and (ii) linkages between a foreign parent bank and its local subsidiary. During and after the global financial crisis, the second source of risk has been stressed by local regulators. Using a nonparametric method based on extreme value theory, we analyze interdependencies in downward risk in the banking sectors of the Czech Republic, Poland, Slovakia, and Turkey during 1994–2013. We find that the risk of contagion from a foreign parent bank to its local subsidiary is substantially smaller than the risk between two local banks.     

Making sense of Brexit losses: An in-depth review of macroeconomic studies

Almost all economic assessments of Brexit conclude that there would be significant losses for both the UK and the EU. This paper examines the driving forces behind these results. We consider the strong economic relationships between the UK and EU both at the sectoral and macroeconomic levels that are at risk from Brexit. We review fifteen studies that explore various Brexit scenarios (hard and soft) and explain why their different methodologies and assumptions yield different degrees of economic damage. Our review concludes that GDP losses for the UK from a hard Brexit range from 1.6% to 7.8%, while a soft Brexit would moderate the losses by roughly half. We also find that potential UK trade agreements with third countries could partially compensate for significant Brexit losses.     

Dynamics of CDS spread indexes of US financial sectors

This article examines the Credit Default Swap (CDS) spread index for three sectors, banking, financial services and insurance, in the short and long run. In the long run, the results show that the index of the insurance sector which sells the long term CDS contracts has the highest adjustment, while the banking sector is not error correcting. In the short run, although the insurance sector CDS spread index has general predictive power of all sector CDS spreads, the evidence suggests that the banking sector particularly leads the financial services and this in turn leads the insurance sector, implying a leading sector CDS pricing role for the banking spreads in the short run. The short run sensitivity Generalized Impulse Response Function (GIRF) and Generalized Variance Decomposition (GVDC) analyses also demonstrate that the sectors’ credit risk responds more to credit events in the banking sector than in the other two sectors other than their own over a 50 day horizon. However, the lowest cross sector CDS shock impacts in the short run come from the insurance sector. These results are useful for regulators wishing to embark on new regulations of these financial institutions such as Basel III.     

中国银行业引进境外战略投资者的绩效分析

引进境外战略投资者是近几年中国银行业改革的一项重要措施。自2001年加入世界贸易组织后,已先后有十几家中资银行引入了境外战略投资者。中国银行业引进境外战略投资者这一改革措施的选取是正确的,但外资持股比例与银行绩效没有必然联系的实证检验结果提示我们,银行绩效的提升不一定非要以外资控股为前提。对于中国这样一个大国来说,保持国内力量的银行控股权应该具有重要战略意义。     

Comparative Analysis of Thresholds of Non-Revolutionary Institutional Change: China and the United States in the 1980s

Ireland has experienced a series of interlocking banking, fiscal, unemployment, and political crises since 2007. We detail the challenges involved in modeling individual moments of the crisis through the lens of balance sheets and transactions matrices among sectors of the Irish society. We conclude with a series of recommendations for models of small open economies.     

Banking sector resilience to financial spillovers

By using a large sample of bank-level data, we analyse whether the spillover effects of US financial shocks differ with the fundamental characteristics of the banking sectors in the affected countries. We find that a banking sector characterized by a higher degree of competition and larger margin of safety is less affected by financial spillovers. The results are robust to the inclusion of bank-level control variables that capture individual banks’ lending capacity.     

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.     

UK's stock market reaction to Brexit process: A tale of two halves

We examine the UK's stock market reaction to 27 events associated with the likelihood of Brexit. Though the overall market reactions to these events is negative, a dissection of these events into the pre and post Brexit referendum events unearth interesting facts. In particular, we find that the market reaction is negative and significant to the events leading up to and including the announcement of Brexit results. This negative reaction is not confined to the day of announcement of the outcome of Brexit referendum only rather it spans over the events that enhanced the likelihood of the Brexit in the pre-Brexit referendum period. However, our results show a positive market reaction to events that occurred after the Brexit referendum. These findings suggest that initially market reacted negatively to the Brexit; however, as the UK's future economic relations with EU started to take a shape, the market started to see the positive side of Brexit. Consistent with this notion, our cross-sectional analysis shows a positive market reaction for the firms that are engaged in foreign sales and that much of the negative market's reaction relates to the firms that openly stated the negative effect of Brexit on their operations. Finally, we do not find evidence of market reaction to UK firms depending on European labor force; however, we do find significantly positive stock market reaction to the firms involved more in international trade. An important caveat of our study is that our reported results are sensitive to the choice of market index.     

Industrial loans and market structure

Based on the observation that financing is one of the main obstacles to create new firms, this paper deals with the interactions between the market structure of both the banking sector and the borrowing industries. We consider that firms’ installation costs are financed by means of industrial loans from specialized banks. With endogenous entry in banking activity as well as in the borrowing industry, we find that a natural oligopoly emerges in both sectors if the entry cost in the industrial sector is small enough, relative to the banks’ entry cost.     

Competition Among Banks, Capital Requirements and International Spillovers

The design of prudential bank capital requirements interacts with the industrial organization of the banking sector, in particular, with the level of competition among banks. Increased competition leads to excessive risk-taking by banks which may have to be counteracted by tighter capital requirements. When capital requirements are internationally uniform but the levels of competition among banks in different countries are not, international spillovers arise on financial integration of these countries. This result begs a more careful analysis of the effect of financial liberalization on the stability of banking sectors in emerging countries. It also calls into question the merits of employing uniform capital requirements across countries that diverge in the industrial organization of their banking sectors.

Policy uncertainty and international financial markets: the case of Brexit

ABSTRACT

This study assesses the impact of the Brexit probability on both the UK and on international financial markets, for the first and the second statistical moments. As financial markets are by nature highly interlinked, one might expect that the uncertainty engendered by Brexit also has an impact on financial markets in several other countries. We first estimate the time-varying interactions between UK policy uncertainty, which to a large extent is attributed to uncertainty about Brexit and UK financial market volatilities. Second, we use two other measures of the perceived probability of Brexit before the referendum, namely daily data released by Betfair and results of polls published by Bloomberg. Based on these data sets, and using both panel and single-country SUR estimation methods, we analyse the Brexit effect on levels of stock returns, sovereign CDS, 10-year interest rates in 19 predominantly European countries, and those of the British pound and the euro. We show that Brexit-induced policy uncertainty will continue to cause instability in key financial markets and has the potential to damage the real economy in both the UK and other European countries. The main losers outside the UK are the ‘GIIPS’ economies: Greece, Ireland, Italy, Portugal and Spain.     

Brexit,the City and the Contingent Power of Finance

Brexit poses a profound challenge to the economic fortunes of the financial services sector in the United Kingdom (UK) because it threatens to sever access to the single market in the European Union (EU). Recognising this, the City of London’s largest financial firms and main representative bodies supported a Remain vote in the June 2016 referendum, and subsequently lobbied for a ‘soft’ Brexit policy to preserve the City’s lucrative passporting rights. Despite this, the government led by Theresa May pursued a ‘hard’ Brexit policy which threatened to leave the UK outside the single market. How can we explain the City’s apparent failure to influence the UK’s Brexit policy? We argue that whilst the UK financial sector wielded formidable latent structural power, its capacity to translate this into instrumental influence in the policy process was constrained by three factors: the political statecraft of Brexit, leading the government to downgrade the concerns of the financial industry; the reconfiguration of institutional structures, which undermined the City’s voice within government; and constraints on business organisation, caused by collective action problems and heterogeneous preferences. These three factors constitute important scope conditions which highlight the contingent power of finance in liberal market economies.     

Portfolio efficiency analysis with SFA: the case of PSI-20 companies

This study aimed to assess the technical efficiency (TE) of individual companies and their respective sectors that are traded on the Portuguese stock market. We accomplished this by combining the internal input variables (e.g., ‘market value and return’) with exogenous variables (e.g., ‘interest income’, ‘depreciation’, ‘cost of goods’, ‘employees’ and ‘net sales’) into a Stochastic Frontier Analysis (SFA) model. The TE of the PSI-20 (Portuguese Stock Index) was estimated using factors that affect efficiency variability. The main advantage of using the SFA approach is its potential to discriminate between measurement error and systematic inefficiencies in the estimation process. The results demonstrated that TE is higher for enterprises in the industrial, construction and distribution sectors, whereas the commercial banking sector has the lowest TE scores. The ‘employees’ and ‘depreciation’ are the variables which most contribute to stock market inefficiency.     

Skill Formation,Immigration and European Integration: The Politics of the UK Growth Model

ABSTRACT

While a reluctant European player now heading for the Exit, the UK was also an enthusiastic adopter of several key EU economic policies – namely, the skills and technology policies of Agenda 2020 and labour mobility. These initiatives worked with existing British policy, and structural biases, to exacerbate the already bifurcated structure of UK capitalism – between the high-paid technology and financial services sector on the one hand, and low-cost, low-wage sectors on the other hand. In particular, and central to the argument of this paper, immigration from Eastern and Central Europe after 2004 helped to sustain low-cost manufacturing and services industries by undermining firms’ incentives to invest in training. This combined with endemic failures in the UK’s skills system, which is heavily geared towards producing graduates with general skills but neglects the needs of mid and lower segments of the labour market. EU integration, therefore, exacerbated cleavages over skills between high- and low-productivity sectors and may have contributed to social divisions that led to Brexit.     

Testing the relationship between competition and efficiency in banking: A panel data analysis

The relationship between competition and efficiency in the banking sectors of five EU countries is investigated using Granger-type causality test estimations. We find positive causation between market power and efficiency, whereas the causality running from efficiency to competition is weak.     

Assessing the macroeconomic impact of alternative macroprudential policies

This article assesses effects on the wider economy and overall costs and benefits of two alternative macroprudential policies - loan-to-value ratios on mortgage lending and variable bank capital adequacy targets. It also traces the potential effects of such policies if introduced prior to the subprime crisis. The work is performed within the National Institute Global Econometric Model, with a focus on Germany, Italy and the UK. Detailed banking sectors and addition of a macroprudential block to our model enable effects of policies to be captured. A systemic risk index tracks the likelihood of the occurrence of a banking crisis and establishes thresholds at which macroprudential policies should be activated by the authorities. Capital adequacy impacts the economy by acting on the spread between borrowing and lending of corporates and households, while loan-to-value transmits through its impact on the housing market. We find generally loan-to-value policy has a lesser effect than capital adequacy on crisis probabilities and net benefits, but there is considerable cross country variation. We show that the introduction of macroprudential policy prior to the crisis would have led to improvement in a number of key macroeconomic measures and might thus have reduced the incidence of the crisis.     

Market structure and credit procyclicality: Lessons from loan markets in the European Union banking sectors

The aim of this paper is to investigate whether the market structure has an impact on procyclicality in the European Union bank loan markets. The cyclical responses of three types of bank loans (residential mortgage loans, consumer loans, and corporate loans) are quantified separately using the interacted panel vector autoregression model at the country level and the single-equation panel regression model at the bank level. Using a sample of 26 European Union countries, we find that the procyclical responses of residential mortgage loans and consumer loans are significantly stronger and prolonged when the banking sector is more concentrated or dominated by foreign banks. However, we find that there are nonlinear relationships between the market structure and credit procyclicality based on bank-level data. We also find some heterogeneities between advanced and transitioning European Union banking sectors. Finally, our findings confirm the leading role of residential mortgages in intensifying credit fluctuations.
