SCREENING AS A UNIFIED THEORY OF DELINQUENCY,RENEGOTIATION, AND BANKRUPTCY

We propose a parsimonious model with adverse selection where delinquency, renegotiation, and bankruptcy all occur in equilibrium as a result of a simple screening mechanism. A borrower has private information about her endowment, and a lender uses random contracts to screen different types of borrowers. In equilibrium, some borrowers choose not to repay and thus become delinquent. The lender renegotiates with some delinquent borrowers. In the absence of renegotiation, delinquency leads to bankruptcy. Applied to mortgage restructuring, our mechanism generates amplification of house‐price shocks through foreclosure spillovers. We also show that government intervention aimed at limiting foreclosures may have unintended consequences.     

LEVERAGED BUYBACKS OF SOVEREIGN DEBT: A MODEL AND AN APPLICATION TO GREECE

The model presented in this article shows that the outcome of a leveraged buyback of sovereign debt depends on the priority structure of the deal. If the institution lending the funds needed for the buyback is senior, the debtor country benefits from the deal: the government debt is reduced, implying a lower probability of default; at the same time, the deal makes the price of outstanding bonds go down, since their recovery rate declines. The opposite holds if the lending institution is junior. If the loan is underpriced, the implied subsidy is shared between the borrowing country and its bondholders, who can benefit from a price increase of their bonds. This is actually what happened with the buyback of Greek sovereign bonds in 2012, as it is shown in the empirical section. Those results do not depend on the share of country's endowment devoted to debt repayment, which instead plays a crucial role in shaping the outcome of unlevered buybacks. (JEL F34, H63)     

PUBLIC DEBT AND PUBLIC INVESTMENT IN AN ENDOGENOUS GROWTH MODEL WITH REAL WAGE RIGIDITIES

We present an endogenous growth model with public capital, public debt and real wage rigidities due to labor market imperfections. Assuming that the primary surplus relative to gross domestic produce (GDP) is a positive function of the debt to GDP ratio, we study growth and employment effects of deficit‐financed public investment using simulations as well as how fiscal policy affects stability of the economy. Further, we contrast the growth rate and the unemployment rate in the deficit scenario with that of the balanced budget scenario. Finally, we compare our results with those obtained in case of flexible wages and full employment.     

MAXIMUM SUSTAINABLE GOVERNMENT DEBT IN THE PERPETUAL YOUTH MODEL

The overlapping‐generations model of Blanchard, based on a constant probability of death, is used to study the maximum level of government debt consistent with the existence of a steady state equilibrium. In both a small open and a closed economy it is shown that maximum sustainable debt robustly occurs where the consumption of individual households reaches zero, the limit of its feasible range. Taxation absorbs all of the household's labour income here. In a closed economy, at this point the real interest rate also hits a ‘ceiling’ given by a simple combination of preference parameters and the death probability.     

OPTIMAL DEBT AND ENDOGENOUS GROWTH IN MODELS OF INTERNATIONAL FINANCE

The International Monetary Fund, the World Bank and the bond rating agencies did not anticipate the crises in Asia 1997–98 and in Argentina 2001 . With this statement in mind, we consider some multi-stage inter-temporal stochastic optimisation models in international finance that imply theoretically founded and empirically measurable Early Warning Signals. The mathematical technique is dynamic programming/stochastic optimal control (DP/SOC).
The variables of interest are the optimal foreign debt, consumption, capital and the growth rate of GDP. They are used as benchmarks of economic performance. By comparing the actual debt to the optimal debt we derive a measure of the sustainability of the debt and vulnerability to default problems. The two sources of uncertainty – the productivity of capital and the real interest rate on the foreign debt – are modeled as stochastic processes. Specific applications of the DP/SOC techniques are given for country defaults in Asia and Latin America, and the US current account deficits.     

CRIME AND EDUCATION IN A MODEL OF INFORMATION TRANSMISSION

We model the decisions of young individuals to stay in school or drop out and engage in criminal activities. We build on the literature on human capital and crime engagement and use the framework of Banerjee (1993) that assumes that the information needed to engage in crime arrives in the form of a rumour and that individuals update their beliefs about the profitability of crime relative to education. These assumptions allow us to study the effect of social interactions on crime. In our model, we investigate informational spillovers from the actions of talented students to less talented students. We show that policies that decrease the cost of education for talented students may increase the vulnerability of less talented students to crime. The effect is exacerbated when students do not fully understand the underlying learning dynamics.     

CORPORATE BANKRUPTCY REORGANIZATIONS: ESTIMATES FROM A BARGAINING MODEL*

This article uses a novel approach to measure the unobserved liquidation value of a firm that relies on the information contained in the allocations that are agreed upon in Chapter 11 negotiations. I estimate a game theoretic model that captures the influence of liquidation value on the equilibrium allocations using a newly collected data set. I find that the liquidation values are higher when the industry conditions are more favorable, and the real interest rates are higher. I use the estimated model to conduct a counterfactual experiment to quantitatively assess the impact of a mandatory liquidation on the equilibrium allocations.     

FISCAL POLICY RULES AND THE SUSTAINABILITY OF PUBLIC DEBT IN EUROPE*

The sustainability of public debt is interpreted as the result of the interaction of fiscal policy with the economic environment, and not as a statistical concept as in most of the recent literature. If debt is not to explode over time, policymakers have to respond to the changing conditions in the macroeconomic environment. This article defines the conditions that will ensure compliance of fiscal policy with the intertemporal budget constraint in the context of Europe's fiscal policy rules. The empirical part of the article reveals that European public debt is sustainable in this respect, but questions regarding long‐run liquidity requirements remain unresolved.     

PARTIALLY DISAGGREGATED HOUSEHOLD‐LEVEL DEBT SERVICE RATIOS: CONSTRUCTION,VALIDATION, AND RELATIONSHIP TO BANKRUPTCY RATES

Using individual‐level debt payments data from a credit bureau, we estimate debt service ratios by debt type for the United States. While highly correlated with the Board of Governors' national debt service ratio, we identify some required payments categories that vary substantively from the aggregate assumptions used in the Board's published data series. Estimating novel state and metropolitan statistical area (MSA)‐level debt service ratios, we show that debt service ratios rose dramatically during the 2000s housing boom in several of the most impacted states and MSAs. Our state‐level debt service ratios are shown to be useful in predicting state bankruptcy rates. (JEL D14, C8, E50)     

COLLUSION AND PREDATION UNDER THE CONDITION OF STOCHASTIC BANKRUPTCY

In this paper, on the basis of the framework of repeated games, we consider the strategic interaction between firms that may face financial constraints and go into bankruptcy when they earn low profit. We demonstrate that under asymmetric information concerning the financial constraints of the rival firm, firms adopt a pricing pattern wherein they switch to high (or collusive) prices after maintaining low prices for some periods. There are always such predatory pricing strategies sustained as equilibria when firms are sufficiently patient. We also show that the set of feasible and individual rational payoffs becomes narrower than that of the ordinal repeated games.     

AN ENDOGENOUS GROWTH MODEL WITH PUBLIC CAPITAL AND SUSTAINABLE GOVERNMENT DEBT*

This paper presents and analyses an endogenous growth model with public capital and public debt. It is assumed that the ratio of the primary surplus to gross domestic income is a positive linear function of the debt income ratio which assures that public debt is sustainable. The paper then derives necessary conditions for the existence of a sustainable balanced growth path for the analytical model. Further, simulations are undertaken in order to gain insight into stability properties of the model and in order to analyse growth effects of deficit financed increases in public investment. The latter is done for the model on the sustainable balanced growth path as well as for the model along the transition path.     

REDISTRIBUTIVE POLITICS AND GOVERNMENT DEBT IN A BORROWING‐CONSTRAINED ECONOMY

We develop a two‐period, three‐class of income model where low‐income agents are borrowing constrained because of capital market imperfections, and where redistributive expenditure is financed by tax and government debt. When the degree of capital market imperfection is high, there is an ends‐against‐the‐middle equilibrium where the constrained low‐income and the unconstrained high‐income agents favour low levels of government debt and redistributive expenditure; these agents form a coalition against the middle. In this equilibrium, the levels of government debt and expenditure might be below the efficient levels, and the spread of income distribution results in a lower debt‐to‐GDP ratio.     

LEARNING-BY-DOING AND ASYMMETRIC INFORMATION IN A MODEL OF MONOPOLY REGULATION*

This paper combines learning-by-doing and asymmetric information in a model of monopoly regulation with and without foreign competition. The principal source of the information asymmetry is unobservable firm effort in the learning process, although unobservable costs are also considered. The major result is that a post-learning all-or-nothing output-contingent lump-sum subsidy can achieve the regulator's complete information welfare maximum. With foreign competition this model can best be thought of as one involving infant industry regulation.     

EFFICIENCY AND LABOR MARKET DYNAMICS IN A MODEL OF LABOR SELECTION

This article characterizes efficient labor market allocations in a labor selection model. The model's crucial aspect is cross‐sectional heterogeneity for new job contacts, which leads to an endogenous selection threshold for new hires. With cross‐sectional dispersion calibrated to microeconomic data, 40% of empirically relevant fluctuations in the job‐finding rate arise, which contrasts with results in an efficient search and matching economy. The efficient selection model's results hold in partial and general equilibrium, as well as with sequential search.     

新古典模型中收入和财富分配持续不平等的动态演化

本文讨论了当个人劳动能力和偏好存在差异的情况下,资本收入和劳动收入分配的差异如何通过遗产机制影响收入和财富分配的持续性不平等程度。论文分析表明:在偏好、个人劳动能力和个人收入的随机冲击的影响下,如果市场是完善的,整个经济系统存在收入和财富分配的稳定不平等状态,而且,这种稳定的不平等状态与初始的财富分配的不平等和一次性的产权配置都是无关的。最后,本文分析了资本收入税和劳动收入税对持续不平等程度的影响,通过分析指出:从长期来看,在劳动能力和初始财富存在差异而偏好没有差异的情况下,征收劳动收入税比征收资本收入税更有利于改善由于能力差异所造成的持续不平等。     

DEBT AND DEPRESSION

We investigate the relationship between public debt ratios and per capita output using episodal data. Episodes of debt and depression occur far more frequently than expected. Growth is lower during episodes of low, moderate, and high debt ratios; while debt ratios are higher during depressions. We look at precedence of entries and exits in overlapping episodes, and the decomposition of the debt ratio during intervals just before and after overlaps. Output movements influence the debt ratio more during exit than entry. Debt movements often precede depressions. Developing countries account for these results almost exclusively. (JEL E32, E62, O47)     

A REGIONAL MODEL OF OIL AND GAS EXPLORATION IN THE UKCS

Existing exploration–discovery models are generally characterised by equations describing the behaviour of exploration, success rates, and discoveries. The present paper adds two equations describing the behaviour of finding costs and exploration efficiency. The model was disaggregated along regional lines. Applying the model to UK Continental Shelf data over the period 1964–2002 produced results that supported the new approach. Analysis of the model dynamics and simulation forecast reveals similarities, but also important differences in the responsiveness of activity in the regions to policy multipliers, implying that uniform policy instruments will produce unequal responses in areas with different levels of maturity.     

RETURNS TO DEBT AND EQUITY IN FARM PRODUCER ORGANIZATIONS

While the capital structure irrelevance proposition is the point of departure in corporate finance, it is unknown if debt‐or‐equity decisions matter to farm producer organizations. To inform decisions of capital acquisition, a panel study is conducted to estimate the relationships of different types of debt (current, long‐term) and equity (allocated, unallocated) to the financial performance of 707 farm producer organizations in the United States during the 2005–2011 period. Using 3,120 observations, the panel analysis indicates net sales in period t is increased by $1.97, $9.59, and $4.01 with an addition of $1 in current debt, allocated equity, or unallocated equity in period t_‐1. Furthermore, the magnitude of the positive relationship of an additional dollar of allocated (unallocated) equity to net income is estimated at $0.32 ($0.14). We thus reject the notion managers and directors of farm producer organizations should decide to use debt or equity with a coin toss.
