Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

Estimation and Inference in Econometrics

This paper constructs a growth model that is consistent with salient features of the Chinese growth experience since 1992: high output growth, sustained returns on capital investments, extensive reallocation within the manufacturing sector, falling labor share and accumulation of a large foreign surplus. The theory makes only minimal deviations from a neoclassical growth model. Its building blocks are financial imperfections and reallocation among firms with heterogeneous productivity. Some firms use more productive technologies than others, but low-productivity firms survive because of better access to credit markets. Due to the financial imperfections, high-productivity firms - which are run by entrepreneurs - must be financed out of internal savings. If these savings are sufficiently large, the high-productivity sector outgrows the low-productivity sector, and attracts an increasing employment share. During the transition, low wage growth sustains the return to capital. The downsizing of the financially integrated sector forces a growing share of domestic savings to be invested in foreign assets, generating a foreign surplus. We test some auxiliary implications of the theory and find robust empirical support.

Growing Like China

This paper constructs a growth model that is consistent with salient features of the recent Chinese growth experience: high output growth, sustained returns on capital investment, extensive reallocation within the manufacturing sector, falling labor share and accumulation of a large foreign surplus. The building blocks of the theory are asymmetric financial imperfections and heterogeneous productivity. Some firms use more productive technologies, but low-productivity firms survive because of better access to credit markets. Due to the financial imperfections, high-productivity firms — which are run by entrepreneurs — must be financed out of internal savings. If these savings are sufficiently large, the high-productivity firms outgrow the low-productivity firms and attract an increasing employment share. The downsizing of the financially integrated firms forces a growing share of domestic savings to be invested in foreign assets, generating a foreign surplus. A calibrated version of the theory can account quantitatively for China’s growth

This paper presents a global model linking individual country vector error-correcting models in which the domestic variables are related to the country-specific variables as an approximate solution to a global common factor model. This global VAR is estimated for 26 countries, the euro area being treated as a single economy. This paper proposes two important extensions of previous research (see Pesaran, Schuermann and Weiner, 2004). First, it provides a theoretical framework where the GVAR is derived as an approximation to a global unobserved common factor model. Also using average pair-wise cross-section error correlations, the GVAR approach is shown to be quite effective in dealing with the common factor interdependencies and international comovements of business cycles. Second, in addition to generalised impulse response functions, we propose an identification scheme to derive structural impulse responses. We focus on identification of shocks to the US economy, particularly the monetary policy shocks, and consider the time profiles of their effects on the euro area. To this end we include the US model as the first country model and consider alternative orderings of the US variables. Further to the US monetary policy shock, we also consider oil price, US equity and US real output shocks.

Exploring the International Linkages of the Euro Area: a Global VAR Analysis

Writings on the macroeconomic impact of capital account liberalization find few, if any, robust effects of liberalization on real variables. In contrast to the prevailing wisdom, I argue that the textbook theory of liberalization holds up quite well to a critical reading of this literature. The lion's share of papers that find no effect of liberalization on real variables tell us nothing about the empirical validity of the theory, because they do not really test it. This paper explains why it is that most studies do not really address the theory they set out to test. It also discusses what is necessary to test the theory and examines papers that have done so. Studies that actually test the theory show that liberalization has significant effects on the cost of capital, investment, and economic growth.

Capital Account Liberalization: Theory, Evidence, and Speculation

Substantial effort has been devoted to reforming China's banking system in recent years. The authorities recapitalized three large state-owned banks, introduced new governance structures, and brought in foreign strategic investors. However, it remains unclear the extent to which currently reported data reflect the true credit risk in loan portfolios and whether lending decisions have started to be taken on a commercial basis. We examine lending growth, credit pricing, and regional patterns in lending from 1997 through 2004 to look for evidence of changing behavior of the large state-owned commercial banks (SCBs). We find that the SCBs have slowed down credit expansion, but that the pricing of credit risk remains undifferentiated and banks do not appear to take enterprise profitability into account when making lending decisions. Controlling for several factors, we find that large SCBs have continued to lose market share to other financial institutions in provinces with more profitable enterprises. The full impact of the most recent reforms will become clear only in several years, however, and these issues should be revisited in future research.

Progress in China's Banking Sector Reform: Has Bank Behavior Changed?

The announcement of the European Union enlargement coincided with a dramatic rise in stock prices in accession countries. This paper investigates the hypothesis that the rise in stock prices was a result of the repricing of systematic risk due to the integration of accession countries into the world market. We found that firm-level stock price changes are positively related to the difference between a firm's local and world market betas. This result is robust to controlling for changes in expected earnings, country effects, and other controls, although the magnitude of the effect is not very large. The differences between local and world betas explain nearly 22 percent of the stock price increase.

This paper explores insurance as a source of financial system vulnerability. It provides a brief overview of the insurance industry and reviews the risks it faces, as well as several recent failures of insurance companies that had systemic implications. Assimilation of banking-type activities by life insurers appears to be the key systemic vulnerability. Building on this experience and the experience gained under the FSAP, the paper proposes key indicators that should be compiled and used for surveillance of financial soundness of insurance companies and the insurance sector as a whole.

Insurance and Issues in Financial Soundness

We explore the relationship between banking sector performance and the quality of regulation and supervision as measured by compliance with the Basel Core Principles for Effective Banking Supervision (BCP). Using BCP assessment results for 65 countries and 1998-2002 panel data for other variables, we find a significant positive impact of higher compliance with BCP on banking sector performance, as measured by nonperforming loans and net interest margin, after controlling for the level of development of the economy and the financial system and macroeconomic and structural factors.

Does Compliance with Basel Core Principles Bring Any Measurable Benefits

We analyze the structure, performance, and role of banking systems in the three member countries of the East African CommunityKenya, Tanzania, and Ugandaagainst the backdrop of recent financial sector reforms. Focusing on the behavior of different types of banks, we find no support for the argument that the presence of large international banks would have an adverse effect on the effectiveness and efficiency of banking sectors in developing countries. International banks are generally more efficient and more active in lending than domestic banks. However, as suggested by the Kenyan experience, the presence of international banks may not lead to increased competition and provision of banking services if weak institutions are allowed to remain in the system.
