International reserves and global interest rates

In this paper we study the relationship between foreign currency international reserve holdings and global interest rates. To guide empirical work we solve a simple, small open-economy model with money, where the central bank manages international reserves to smooth inflation over time. This model shows that changes in interest rates are positively related to the target level of reserves. As a consequence interest rate hikes increase reserve transfers, defined as the change in international reserves net of the interest earned on reserves. Using quarterly data for 75 countries between 2000 and 2013, we document a positive relationship between interest-rate changes and reserve transfers as a share of GDP, that is consistent with the model.     

西部地区上市公司债务融资效应的实证研究——基于2007-2010年的经验数据

本文选取沪市西部地区53家上市公司作为研究样本,着重研究债务融资的税盾效应与财务杠杆效应。基于样本公司的债务融资现状,通过因子分析、主成分分析与多元回归分析揭示了债务融资效应与各影响因素之间的关联程度及显著水平。结论表明,当总资产息税前利润率大于债务利息率时,提高资产负债率,税盾效应、财务杠杆效应同时增大,进而增强债务融资效应;当总资产息税前利润率小于债务利息率时,提高资产负债率,税盾效应增大,财务杠杆表现为负效应,债务融资效应呈现不确定性。     

Trading and Shareholder Democracy

We study shareholder voting in a model in which trading affects the composition of the shareholder base. Trading and voting are complementary, which gives rise to self-fulfilling expectations about proposal acceptance and multiple equilibria. Prices and shareholder welfare can move in opposite directions, so the former may be an invalid proxy for the latter. Relaxing trading frictions can reduce welfare because it allows extreme shareholders to gain more weight in voting. Delegating decision-making to the board can help overcome collective action problems at the voting stage. We also analyze the role of index investors and social concerns of shareholders.     

The Irrelevance of Capital Structure for the Impact of Inflation on Investment

Studies concerning the effect of inflation on firms' investment decisions suggest that the form of financing is relevant in assessing the effect of inflation on investment. This paper demonstrates that when the equilibrium relationship between market rates of return on bonds and stocks is considered, the effect of inflation on investment is independent of the capital structure. The paper also shows that when the ‘Fisher effect’ is assumed to hold, the cut-off rate of return on investment declines with anticipated inflation independently of the financing. However, if the real interest rate rises with inflation, inflation may increase the cut-off rate.     

Bank and Nonbank Lenders and the Commercial Mortgage Market

This paper develops an equilibrium model of the commercial mortgage market that includes the sequence from commitment to origination and allows testing for differences by type of lender. From borrowers, loan demand is based on the income yield, capital gains, and expectations about return distributions. Lenders use prices such as mortgage rates and their distributions, and quantities in underwriting standards. There are separate equilibria in the markets for loan commitments and originations. Bank and nonbank lenders are not restricted to the same lending technology, nor to the weights placed on mortgage rates as opposed to underwriting standards. Empirical results for the United States commercial mortgage market indicate that banks use interest rates in allocating credit while nonbanks rely on underwriting standards, notably the loan-to-value ratio. A consequence is that nonbanks have a clientele incentive towards making low cap rate loans compensated by low loan-to-value ratios.     

Non-implementability of Arrow–Debreu equilibria by continuous trading under volatility uncertainty

In diffusion models, a few suitably chosen financial securities allow to complete the market. As a consequence, the efficient allocations of static Arrow–Debreu equilibria can be attained in Radner equilibria by dynamic trading. We show that this celebrated result generically fails if there is Knightian uncertainty about volatility. A Radner equilibrium with the same efficient allocation as in an Arrow–Debreu equilibrium exists if and only if the discounted net trades of the equilibrium allocation display no ambiguity in the mean. This property is violated generically in endowments, and thus Arrow–Debreu equilibrium allocations are generically unattainable by dynamically trading a few long-lived assets.     

On the pricing of intermediated risks: Theory and application to catastrophe reinsurance

We model the equilibrium price and quantity of risk transfer between firms and financial intermediaries. Value-maximizing firms have downward sloping demands to cede risk, while intermediaries, who assume risk, provide less-than-fully-elastic supply. We show that equilibrium required returns will be “high” in the presence of financing imperfections that make intermediary capital costly. Moreover, financing imperfections can give rise to intermediary market power, so that small changes in financial imperfections can give rise to large changes in price.     

Reputation and turnover

We consider a repeated duopoly game where each firm privately chooses its investment in quality, and realized quality is a noisy indicator of the firm's investment. We focus on turnover equilibria in which a low‐quality realization is penalized by lowering future demand of the firm that delivered this quality. We determine when a turnover equilibrium that gives higher welfare than the static equilibrium exists and how this relates to market fundamentals. We also derive comparative statics properties, and we characterize a set of investment levels and, hence, payoffs that turnover equilibria sustain.     

Risk-Shifting Incentives and Signalling Through Corporate Capital Structure

This paper examines optimal corporate financing arrangements under asymmetric information for different patterns of temporal resolution of uncertainty in the underlying technology. An agency problem, a signalling problem and an agency-signalling problem arise as special cases. The associated informational equilibria and the optimal financing arrangements are characterized and compared. In the agency-signalling equilibrium the private information of corporate insiders at the time of financing is signalled through capital structure choices which deviate optimally from agency-cost minimizing financing arrangements, which in turn induce risk-shifting incentives in the investment policy. In the pure signalling case the equilibrium is characterized by direct contractual precommitments to implement investment policies which are riskier than pareto-optimal levels. Empirical implications for debt covenants and the announcement effect of investment policies and leverage increasing transactions on existing stock and bond prices are explicitly derived.     

Fully revealing equilibria with suboptimal investment

Myers and Majluf [Myers, S.C., Majluf, N.S., 1984. Corporate financing and investment decisions when firms have information that investors do not have. Journal of Financial Economics 13, 187–221.] showed that mispriced securities can lead managers with private information to invest inefficiently. It seems plausible that this problem would disappear in a fully revealing equilibrium, since information asymmetries are resolved and securities are priced correctly. In fact, Constantinides and Grundy [Constantinides, G.M., Grundy, B.D., 1989. Optimal investment with stock repurchase and financing as signals. Review of Financial Studies 2, 445–465.] claim that, in their model, any fully revealing equilibrium has efficient investment. This claim is incorrect, as infinitely many inefficient equilibria exist for the very example they work out. The inefficient outcomes survive the standard signaling-game equilibrium refinements. There are also examples that have fully revealing equilibria with inefficient investment but none with efficient investment.     

Non-Segmented Equilibria Under Differential Taxation: Evidence from the Canadian Government Bond Market

This paper investigates tax effects in the Canadian government bond market during the period 1964–1986. Unlike previous studies, we apply both statistical and nonstatistical tests to analyze clientele effects and market equilibria. The results divide the sample into two distinct periods of time, with the end of 1976 marking the division. We find that taxeffects are almost non-existent in the Canadian government bond market before the end of 1976, but are predominant in the post-1976 period. Non-segmented market equilibria cannot be rejected before 1977, but are strongly rejected after 1976. In fact, segmented equilibria with clientele effects in both quantities and prices characterize the entire five year period from 1982 to 1986. These findings are consistent with tax reforms, government deficit financing and interest rate fluctuations in Canada during our sample period.     

Interest on bank reserves and optimal sweeping

A key rationale offered by the Federal Reserve for the payment of interest on reserves was to remove the incentive for banks to operate sweep accounts. Sweeping shifts funds from transactions deposits subject to reserve requirements to non-reservable deposits. This paper extends a conventional banking model to analyze sweeping behavior. Sweeping responds positively to increases in bank loan rates and reserve ratios and negatively to increases in the interest rate on reserves or exogenous increases in bank equity. Sweeping generates greater responsiveness in lending to changes in loan rates or the interest rate on reserves and lower responsiveness to changes in reserve ratios or equity than in its absence. Empirical analysis of an explicit condition that we derive suggests that, with an unchanged reserve requirement, the Fed could eliminate sweeping by setting the interest rate on reserves to no less than approximately 4% points below the market loan rate.     

Money,Bonds, and the Liquidity Trap

This paper examines a search model of money and public bonds in which coordination frictions lead to multiple, Pareto ranked equilibria. Whether money and bonds are substitutes or complements, is not a primitive of the economy, but an equilibrium outcome. There exists an equilibrium resembling a liquidity trap, in which money and bonds are perfect substitutes, interest rates are zero, and monetary policy is ineffective; and a superior equilibrium in which money and bonds are complements, interest rates are positive and monetary policy has a liquidity effect. On this view, the liquidity trap is a belief-driven phenomenon.

FOREIGN EXCHANGE AND CROSS-BORDER VALUATION

Should a corporate financial manager analyze a cross-border investment proposal from the perspective of the foreign currency or the home currency? The conventional wisdom among economists is that it doesn't matter–the valuation of an asset should be the same in one currency as in another, given the spot FX rate. This assertion implies that it is irrelevant whether we analyze an overseas investment's NPV in the home currency or the foreign currency, as long as we use consistent cross-border conversions.
But what happens if managers' foreign exchange forecasts differ from the efficient markets forecast that is implicit in interest rates? In that case, as this article demonstrates through a series of examples, managers' FX forecasts can affect their investment, hedging, and financing decisions.     

On stock-based loans

We investigate the equilibrium interest rate charges on non-recourse and recourse loans secured by stock. In such loans, the client retains the option to prepay and recover the collateral stock. We adopt a structural model of the firm where debt levels, with endogenous bankruptcy, affect equity dynamics. Complicating matters, the link between total equity and the price of a share of stock that forms the collateral depends on the extent of dilutions and buybacks that occur. For levered firms, due to dilution in bad states of nature, stock prices typically fall faster than equity values; and for firms that engage in buybacks in good states of nature, stock prices will rise faster than equity values. Banks that ignore these features underestimate the equilibrium interest rate charge on stock-based loans. We provide an analysis of individual stock-based loans and their portfolio characteristics, the latter of which can be used by banks to ascertain capital requirements.     

Distortionary Taxation, Debt, and the Price Level

This paper compares the determinacy of equilibria under exogenous interest rates in an economy with a cash constraint, in which taxation is lump-sum or distortionary. Under passive fiscal policies lump-sum taxes generate nominal indeterminacy, while with distortionary taxes indeterminacy can be real, but not purely nominal. In general, under distortionary taxation uniqueness of the equilibrium allocation depends on monetary and fiscal policy interactions through taxes, debt, and interest rates. To illustrate this principle, we consider balanced-budget policies under distortionary income taxation and show that a unique equilibrium allocation prevails if interest rates are set consistent with long-run deflation. A separate section extends the analysis to endogenous interest rates.
