Drivers of Cross-Border Banking in Sub-Saharan Africa
Mr. Paul Henri Mathieu
,
Mr. Marco Pani
,
Shiyuan Chen
, and
Mr. Rodolfo Maino
Using data collected from pan-African banks’ (PABs), balance sheets and other sources (Orbis, Fitch), this study identifies some key patterns of cross-border investment in bank subsidiaries by key banking groups in sub-Saharan Africa (SSA) and discusses some of the determinants of this investment. Using a gravity model relating the annual value of a banking group’s investment in the net equity of its subsidiaries to a set of explanatory variables, the analysis finds that cross-border banking is in part driven by a search for yield, diversification, and expansion for strategic reasons.

Does the Stock Market Boost Firm Innovation?: Evidence from Chinese Firms
Hui He
,
Hanya Li
, and
Jinfan Zhang
The paper analyses the effect of the stock market on firm innovation through the lens of initial public offering (IPO) using uniquely matched Chinese firm-level data. We find that IPOs lead to an increase in both the quantity and quality of firm innovation activity. In addition, IPOs expand a firm’s scope of innovation beyond its core business. The impact of IPOs on firm innovation varies across financial constraints, corporate governance, and ownership structures. Our results further illustrate that IPOs induce a firm to increase the number of inventors and enable better retention of existing inventors after the IPO. Finally, we show that the enhanced innovation activity resulting from IPOs increases a firm’s Tobin’s Q in the long run.

Benchmarking Banking Sector Efficiency Across Regional Blocks in Sub-Saharan Africa: What Room for Policy?
Mr. Francois Boutin-Dufresne
,
Santiago Peña
,
Mr. Oral Williams
, and
Mr. Tomasz A. Zawisza
This paper examines the determinants of net interest margins in four regional blocks in Sub-Saharan Africa and one comparator block in the Eastern Caribbean. Using bank-level data, we find that countries with a high level of operating costs, a high ratio of equity to total assets and high treasury bill interest rates have higher net interest margins. Moreover, high operating costs are associated with low measures of institutional quality and a small size of bank operations. We find support for the view that market structure is also partly responsible for high net interest margins in Sub-Saharan Africa. If interpreted causally, high operating costs and a high ratio of equity to total assets and, indirectly, institutional factors such as the rule of law, are the most important factors in accounting for high interest margins in the East African Community, relative to other regions.

Data-Rich DSGE and Dynamic Factor Models
Mr. Maxym Kryshko
Dynamic factor models and dynamic stochastic general equilibrium (DSGE) models are widely used for empirical research in macroeconomics. The empirical factor literature argues that the co-movement of large panels of macroeconomic and financial data can be captured by relatively few common unobserved factors. Similarly, the dynamics in DSGE models are often governed by a handful of state variables and exogenous processes such as preference and/or technology shocks. Boivin and Giannoni(2006) combine a DSGE and a factor model into a data-rich DSGE model, in which DSGE states are factors and factor dynamics are subject to DSGE model implied restrictions. We compare a data-richDSGE model with a standard New Keynesian core to an empirical dynamic factor model by estimating both on a rich panel of U.S. macroeconomic and financial data compiled by Stock and Watson (2008).We find that the spaces spanned by the empirical factors and by the data-rich DSGE model states are very close. This proximity allows us to propagate monetary policy and technology innovations in an otherwise non-structural dynamic factor model to obtain predictions for many more series than just a handful of traditional macro variables, including measures of real activity, price indices, labor market indicators, interest rate spreads, money and credit stocks, and exchange rates.

Efficiency-Adjusted Public Capital and Growth
Mr. Sanjeev Gupta
,
Mr. Alvar Kangur
,
Mr. Abdoul A Wane
, and
Mr. Chris Papageorgiou
This paper constructs an efficiency-adjusted public capital stock series and re-examines the public capital and growth relationship for 52 developing countries. The results show that public capital is a significant contributor to economic growth. Although the estimated coefficient for the income share of public capital is larger in middle- than in low-income countries, the opposite is true for the marginal product of public capital. The quality of public investment, as measured by variables capturing the adequacy of project selection and implementation, are statistically significant in explaining variations in economic growth, a result mainly driven by low-income countries.

International Pricing of Emerging Market Corporate Debt: Does the Corporate Matter?
Ms. Sonja Keller
and
Mr. Ashoka Mody
We examine risk spreads charged on corporate bonds placed by emerging market borrowers on international exchanges. While global developments have an important effect on spreads, changes in firm-level default risk also matter significantly in a way consistent with theory and experience in mature markets. In contrast, except during periods of financial crisis, country factors play a limited role. These findings go against the supposition that limited information on emerging market firms or significant agency problems prevent firm-level credit discrimination by international investors. The firm-level information capitalization into spreads possibly reflects protection afforded by the exchange listing on international markets.

Valuation of Unlisted Direct Investment Equity
Thomas Elkjaer
,
Jannick Damgaard
, and
Emmanuel O. Kumah
This paper analyzes the seven valuation methods for unlisted direct investment equity included in the recently adopted IMF Balance of Payments and International Investment Position Manual, Sixth Edition (BPM6). Based on publicly available Danish data, we test the three methods that are generally applicable and find that the choice of valuation method and estimation technique can have a highly significant impact on the international investment position, pointing to the need for further harmonization. The results show that the price-to-book value method generates more robust market value estimates than the price-to-earnings method. This finding suggests that the valuation basis for the forthcoming Coordinated Direct Investment Survey - own funds at book value -will provide useful information for compiling the international investment position.

Solving for Country Portfolios in Open Economy Macro Models
Michael B. Devereux
and
Mr. Alan Sutherland
This paper presents a general approximation method for characterizing time-varying equilibrium portfolios in a two-country dynamic general equilibrium model. the method can be easily adapted to most dynamic general equilibrium models, it applies to environments in which markets are complete or incomplete, and it can be used for models of any dimension. Moreover, the approximation provides simple, easily interpretable closed form solutions for the dynamics of equilibrium portfolios.

The Use of Encompassing Tests for Forecast Combinations
Turgut Kisinbay
The paper proposes an algorithm that uses forecast encompassing tests for combining forecasts. The algorithm excludes a forecast from the combination if it is encompassed by another forecast. To assess the usefulness of this approach, an extensive empirical analysis is undertaken using a U.S. macroecoomic data set. The results are encouraging as the algorithm forecasts outperform benchmark model forecasts, in a mean square error (MSE) sense, in a majority of cases.

Habit Formation and Persistence in Individual Asset Portfolio Holdings: The Case of Italy
Ms. Sònia Muñoz
This paper uses six waves of the Bank of Italy Survey of Households Income and Wealth to explore the dynamics of asset portfolio ownership. The household asset portfolio decision is a choice among discrete alternatives, and I model the problem in a multinomial framework. I focus on a particularly important feature of household portfolio behavior: the infrequency of portfolio allocation changes. I find evidence of strong unobserved heterogeneity through time-varying error components, which I interpret as taste persistence in both the risky and safe asset participation decisions. I estimate the model using the method of maximum smoothly simulated likelihood.
