The valuation of inflation‐indexed and FX convertible bonds

This paper derives a valuation model of inflation‐indexed convertible bonds that incorporates the firm's stock price, inflation indexing and the firm's credit risk. The pricing of inflation‐indexed convertible bonds traded on the Tel‐Aviv Stock Exchange (TASE) was empirically tested by using a comprehensive database. The study is the first to empirically test the pricing of convertibles in emerging markets. It was found that the theoretical values for the bonds are, on average, 1.94% higher than the observed market prices. Unlike previous studies, it was found that the underpricing increases with the moneyness of the convertible. It was found that as the maturity lengthens, the underpricing increases. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:634–655, 2008     

Small Business Credit Scoring and Its Pitfalls: Evidence from Japan

This paper studies the Japanese credit scoring market using data on 2,000 small and medium‐sized enterprises and a small business credit scoring (SBCS) model widely used in the market. After constructing a model for determining a bank's profit maximization, some simulation exercises are conducted, and pitfalls of lending based on SBCS are indicated. The simulation results suggest that the reason why SBCS loan losses occur would be the combination of adverse selection and window‐dressing problems. In addition, omitted variable bias and transparency of financial statements are important.     

MONETARY PRICE RULES FOR ALTERNATIVE STEADY-STATE REGIMES

In the context of elementary models, this study presents an analysis of how disequilibrium can persist. The central result involves a decentralized economy in which agents respond to local excess demand. Attempting to determine the equilibrium inflation rate or its rate of change as well as the equilibrium price level (rather than the latter only) on the basis of excess demand levels alone, is a time consuming process which can lead to cycles. The inflation rate will lag behind its steady-state value resulting in market disequilibrium when the two coincide. Activist policy is required if equilibrium is to be restored without severe unemployment during the transition.     

The monetary explanation of inflation: The experience of three major OPEC economies

The purpose of this paper is to analyze and to test empirically the monetary explanation of inflation in the case of the moderate inflationary experience of three major OPEC economies over the last two decades. The estimated model takes into account the underlying money demand relationship and pays careful attention to the model's lag specifications. The empirical results show that the monetary model of inflation adequately explains the inflationary process in each of the countries studied. These empirical results, furthermore, are econometrically valid insofar as they are not plagued with significant simultaneous-equation bias. In addition, the estimated equations are also found to exhibit structural stability over time.     

THE DIAMOND OF MACROECONOMIC EQUILIBRIA AND NON‐INFLATIONARY EXPANSION

This paper combines the microeconomic foundations of earlier models of a range of equilibrium rates of employment to generate a model with a diamond of equilibria. Analysis of the diamond model shows that for a depressed economy an expansionary aggregate demand policy can, without violating rational expectations of inflation, generate a central proposition of Keynesian economics—a non‐inflationary expansion (NIE), that is a permanent increase in employment without increasing inflation. The microeconomic foundations of the model draw on ideas of customer markets, reference dependence and loss aversion. It is also shown that the possibility of achieving an NIE is enhanced if a macro price policy, such as incomes policy or inflation targeting, accompanies the expansion in aggregate demand.     

Accelerating Sales in Start‐Ups: A Domain Planning,Network Reliance,and Resource Complementary Perspective

Business planning is central to entrepreneurship and of immense interest in explaining venture development. This study investigates how planning in different functional domains, and network reliance for domain planning, relate to speed of initial sales success. Drawing from a sample of founders in the high‐technology sector, we find differential planning effects—market planning lengthens the time to sales whereas technology planning reduces time to sales. Further, we find that founders' reliance on network sources of help for market planning, relative to solo planning, simultaneously complements both market and technology planning and reduces time to sales. Our findings illustrate domain planning, network reliance, and resource complementarities as important to venture development.     

TESTING WAGE AND PRICE PHILLIPS CURVES FOR THE UNITED STATES

This paper demonstrates how the labour and product markets interact in determining as outcome a generalized reduced‐form price Phillips curve. For the labour market we consider a wage Phillips curve and for the product market a price Phillips curve. We estimate separately the wage and price Phillips curves for the USA, using ordinary least squares, non‐parametric estimation and three‐stage least squares techniques. The finding is that wages are always more flexible than prices with respect to their respective demand pressure and that price inflation responds somewhat more to a medium‐run cost pressure than does wage inflation. The implications for macroeconomic stability are demonstrated. We also show—as a link between product and labour markets—that employment is related to output as Okun's law states. In comparing linear and non‐linear estimates of the wage and price Phillips curves we find furthermore that for some relationships non‐linearities are important while not for others. Although overall the non‐linear estimates tend to confirm our linear estimates, non‐linearities in some relationships of the Phillips curve are important as well.     

Inflation Derivatives Under Inflation Target Regimes

Inflation targeting—the central bank practice of attempting to keep inflation levels within fixed bounds around a quantitative target—has been adopted by more than 20 economies. Such practice has an important impact on the stochastic nature of inflation and, consequently, on the pricing of inflation derivatives. We develop a flexible model of inflation targeting in which the central bank's intervention to steer inflation toward the target depends on past deviations and the policymaker's ability and will to enforce the target. We use our model to price inflation derivatives and demonstrate the impact of inflation targeting on derivative pricing.     

Subnational home market bias in Vietnam: Evidence from enterprise‐level data

This paper contributes to the home (market) bias literature where administrative or political borders limit trade across borders. Home bias is well documented at the national and subnational level. To sort out macro (e.g., location characteristics) and micro (e.g., enterprise characteristics) factors behind home bias, we use small and medium‐sized enterprise (SME) data from Vietnam. Using the fractional multinomial logit model, we find that the proportion of SME sales outside of their home markets is positively associated with enterprise size, age, number of business association memberships and the distance of SMEs' most important supplier. In contrast, the proportion of SME sales to neighbouring provinces is negatively associated with the share of SME production for final consumption. Besides enterprise‐level frictions, market characteristics matter too. The proportion of SME sales to customers in their home markets is negatively associated with home or neighbouring provinces' governance quality, while the proportion of sales to customers in neighbouring provinces is positively associated with these areas' governance quality. These suggest that good governance frees SME resources for use in selling to less familiar markets.     

MULTIPLICATIVE APPROXIMATION OF WEALTH PROCESSES INVOLVING NO‐SHORT‐SALES STRATEGIES VIA SIMPLE TRADING

A financial market model with general semimartingale asset–price processes and where agents can only trade using no‐short‐sales strategies is considered. We show that wealth processes using continuous trading can be approximated very closely by wealth processes using simple combinations of buy‐and‐hold trading. This approximation is based on controlling the proportions of wealth invested in the assets. As an application, the utility maximization problem is considered and it is shown that optimal expected utilities and wealth processes resulting from continuous trading can be approximated arbitrarily well by the use of simple combinations of buy‐and‐hold strategies.     

Securities as a hedge against inflation: 1910–1969

How well have marketable securities performed as a hedge against inflation?The question is a very old one to which many writers have addressed themselves. The evolutionary nature of financial markets, financial theory, and financial instruments requires continued reevaluation of previous investment decisions. The purpose of this study is to review the performance record of 14 risk classes of securities, which range from long-term government bonds through five different classes of common stock. The average annual investment relatives adjusted for price-level changes are compared for various periods during which the price level is essentially stable, rising, and falling.

Quantitative Easing and Liquidity in the Japanese Government Bond Market

The “Quantitative and Qualitative Monetary Easing” enacted immediately after the inauguration of Bank of Japan Governor Kuroda brought violent fluctuations in the prices of government bonds and deteriorated market liquidity. Does a central bank's government bond purchasing policy generally reduce market liquidity? Do conditions exist that can prevent such a decrease? This study analyzes how the Bank of Japan's purchasing policy changes influenced market liquidity. The results reveal that three specific policy changes contributed significantly to improving market liquidity: (i) increased purchasing frequency; (ii) a decrease in the purchase amount per auction; and (iii) reduced variability in the purchase amounts. These policy changes facilitated investors' purchase schedule expectations and helped reduce market uncertainty. The evidence supports the theory that the effect of government bond purchasing policy on market liquidity depends on the market's informational environment.     

RISK‐MINIMIZATION FOR LIFE INSURANCE LIABILITIES WITH DEPENDENT MORTALITY RISK

In this paper, we study the pricing and hedging of typical life insurance liabilities for an insurance portfolio with dependent mortality risk by means of the well‐known risk‐minimization approach. As the insurance portfolio consists of individuals of different age cohorts in order to capture the cross‐generational dependency structure of the portfolio, we introduce affine models for the mortality intensities based on Gaussian random fields that deliver analytically tractable results. We also provide specific examples consistent with historical mortality data and correlation structures. Main novelties of this work are the explicit computations of risk‐minimizing strategies for life insurance liabilities written on an insurance portfolio composed of primary financial assets (a risky asset and a money market account) and a family of longevity bonds, and the simultaneous consideration of different age cohorts.     

Derivative Ruination in the 1990s: Les Apparences sont Trompeuses

A spectacular financial revolution spanning 20 years created new securities deriving from other securities, which trade in volumes of trillions of dollars in markets, now thought to be the largest and more important in the world. Known as swaps, swaptions, index futures, puttable bonds, collateralized mortgage obligations, stripped bonds, options, and futures, among other exotic names, these financial contracts were designed as a means of laying off risk involving conventional business transactions. This article details massive abuses in the proper use of these insurance products, which resulted in billions of dollars of speculation losses suffered by Procter & Gamble, Gibson Greeting Cards, Orange County California, Metallgesellschaft AG, various‐public employees' retirement funds—and which brought down one of Europe's oldest merchant banks, Barings PLC. © 2001 John Wiley & Sons, Inc.     

Inflation and Financial Statement Analysis in the International Accounting Classroom

This article provides an exercise for students to contemplate the effects of inflation during financial statement analysis. Even small amounts of inflation accumulating over time can grow to distort a company's reported financial position and results of operations. The growing economies in emerging markets, the international market for oil, and other economic factors threaten to increase inflation rates in the future. As a result of changing global conditions, interest in inflation accounting is expected to increase. The exercise we suggest in this article provides an efficient tutorial on the potential effects of inflation on financial statement analysis and on the application of International Accounting Standard 29 in hyperinflationary environments.

ASSET PRICE BUBBLES IN INCOMPLETE MARKETS*

This paper studies asset price bubbles in a continuous time model using the local martingale framework. Providing careful definitions of the asset's market and fundamental price, we characterize all possible price bubbles in an incomplete market satisfying the “no free lunch with vanishing risk (NFLVR)” and “no dominance” assumptions. We show that the two leading models for bubbles as either charges or as strict local martingales, respectively, are equivalent. We propose a new theory for bubble birth that involves a nontrivial modification of the classical martingale pricing framework. This modification involves the market exhibiting different local martingale measures across time—a possibility not previously explored within the classical theory. Finally, we investigate the pricing of derivative securities in the presence of asset price bubbles, and we show that: (i) European put options can have no bubbles; (ii) European call options and discounted forward prices have bubbles whose magnitudes are related to the asset's price bubble; (iii) with no dividends, American call options are not exercised early; (iv) European put‐call parity in market prices must always hold, regardless of bubbles; and (v) futures price bubbles can exist and they are independent of the underlying asset's price bubble. Many of these results stand in contrast to those of the classical theory. We propose, but do not implement, some new tests for the existence of asset price bubbles using derivative securities.     

Foreign bank lending: Evidence from the global financial crisis

We exploit highly disaggregated bank-firm data to investigate the dynamics of foreign vs domestic credit supply in Italy around the period of the Lehman collapse, which brought a sudden and unexpected deterioration of economic conditions and a sharp increase in credit risk. Taking advantage of the presence of multiple lending relationships to control for credit demand and risk at the individual-firm level, we show that foreign lenders restricted credit supply (to the same firm) more sharply than their domestic counterparts. A number of exercises testing alternative explanations for this result suggest that such more intense restriction also reflects the (functional) distance between a foreign bank's headquarter and the Italian credit market.     

Call Auction Transparency and Market Liquidity: Evidence from China

This paper uses the natural experiment offered by the Shanghai Stock Exchange to investigate the impact of opening call auction transparency on market liquidity. We find that the dissemination of indicative trade information during the pre‐open call auction session leads to an overall improvement in stock liquidity in the continuous trading session. Bid‐ask spreads narrow in the first trading hour because adverse selection risk fell significantly and there is less price volatility in the continuous market. This effect is greater for actively traded securities than illiquid securities. Our findings are robust for different lengths of sample period, different lengths of trading hours after market open, and stocks that had (and had not) reformed the share split structure during our research period.
