In this paper, we examine the ability of the contingent claims approach (CCA) to identify corporate sector and economy-wide vulnerabilities. We apply the Moody`s M/Risk model, which uses aggregated CCA principles, to assess vulnerabilities retroactively in two historical country cases. The results indicate that the method may prove helpful in identifying corporate sector vulnerabilities and estimating the associated value of risk transfer across interrelated balance sheets of the corporate, financial, and public sectors.

Black and Scholes (1973) and Merton (1973, 1974) (hereafter referred to as BSM) introduced the contingent claim approach (CCA) to the valuation of corporate debt and equity. The BSM modeling framework is also named the 'structural' approach to risky debt valuation. The CCA considers all stakeholders of the corporation as holding contingent claims on the assets of the corporation. Each claim holder has different priorities, maturities and conditions for payouts. It is based on the principle that all the assets belong to all the liability holders.The BSM modeling framework gives the basic fundamental version of the structural model where default is assumed to occur when the net asset value of the firm at the maturity of the pure-discount debt becomes negative, i.e., market value of the assets of the firm falls below the face value of the firm's liabilities. In a regime of limited liability, the shareholders of the firm have the option to default on the firm's debt. Equity can be viewed as a European call option on the firm's assets with a strike price equal to the face value of the firm's debt. Actually, CCA can be used to value all the components of the firm's liabilities, equity, warrants, debt, contingent convertible debt, guarantees, etc.In the four volumes we present the major academic research on CCA in corporate finance starting from 1973, with seminal papers of Black and Scholes (1973) and Merton (1973, 1974). Volume I covers the foundation of CCA and contributions on equity valuation. Volume II focuses on corporate debt valuation and the capital structure of the firm. Volume III presents empirical evidence on the valuation of debt instruments as well as applications of the CCA to various financial arrangements. The papers in Volume IV show how to apply the CCA to analyze sovereign credit risk, contingent convertible bonds (CoCos), deposit insurance and loan guarantees. Volume 1: Foundations of CCA and Equity ValuationVolume 1 presents the seminal papers of Black and Scholes (1973) and Merton (1973, 1974). This volume also includes papers that specifically price equity as a call option on the corporation. It introduces warrants, convertible bonds and taxation as contingent claims on the corporation. It highlights the strong relationship between the CCA and the Modigliani-Miller (M&M) Theorems, and the relation to the Capital Assets Pricing Model (CAPM). Volume 2: Corporate Debt Valuation with CCAVolume 2 concentrates on corporate bond valuation by introducing various types of bonds with different covenants as well as introducing various conditions that trigger default. While empirical evidence indicates that the simple Merton's model underestimates the credit spreads, additional risk factors like jumps can be used to resolve it. Volume 3: Empirical Testing and Applications of CCAVolume 3 includes papers that look at issues in corporate finance that can be explained with the CCA approach. These issues include the effect of dividend policy on the valuation of debt and equity, the pricing of employee stock options and many other issues of corporate governance. Volume 4: Contingent Claims Approach for Banks and Sovereign DebtVolume 4 focuses on the application of the contingent claim approach to banks and other financial intermediaries. Regulation of the banking industry led to the creation of new financial securities (e.g., CoCos) and new types of stakeholders (e.g., deposit insurers).

In this issue, a team of economists look at approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or permanent phenomenon. Era Dabla-Norris and Gabriela Inchauste examine what drives the growth of firms, with a focus on informality and regulations. Evan Tanner and Issouf Samake use a vector autoregression approach to examine the probabilistic sustainability of public debt in Brazil. Mexico, and Turkey. And Rachel Glennerster and Yongseok Shin ask whether transparency pays?that is, does the frequency and accuracy of macroeconomic information released to the public lead to lower borrowing costs in sovereign debt markets?

In recent years, firms in emerging market countries have increased borrowing, particularly in foreign currency, owing to easy access to global capital markets, prolonged low interest rates and good investment opportunities. This paper discusses the trends in emerging market corporate debt and leverage, and illustrates how those firms are vulnerable to interest rate, exchange rate and earnings shocks. The results of a stress test show that while corporate sector risk remains moderate in most emerging economies, a combination of macroeconomic and financial shocks could significantly erode firms’ ability to service debt and lead to higher debt at risk, especially in countries with high shares of foreign currency debt and low natural hedges.
