Balance of payments accounting and exchange rate dynamics

The balance of payments is an accounting identity. Many wonder how the current and capital accounts, which add up to zero, can influence exchange rates. This paper shows how payment flows arising from balance of payments imbalances affect the demands for different currencies in the foreign exchange market over time. Based on a dynamical system approach, the paper demonstrates how international payments evolve depending on the joint dynamic behaviour of different balance of payments components. It finds that international payments and exchange rates interact in fundamentally different ways depending on whether a country restricts its capital inflows and outflows, whether capital flows are accommodating or autonomous and whether the exchange rate is fixed, flexible or, say, governed by a crawling peg. Empirical evidence from major industrial countries as well as from countries hit by currency crises support the paper's theoretical predictions.     

Why the structure of capital and the useful lives of its components matter: A test based on a model of Austrian descent

This paper centers on the structure of capital and the useful lives of its components by considering an economy with two representative firms, one producing a necessity and another producing a luxury. This difference determines their reinvestment opportunities. Therefore, while the one applies replacement, the other adopts scrapping. However, as these capital policies lead to different service lives, the analysis confronts the issues raised by Miller (Review of Income and Wealth 29:284–296, 1982, Review of Income and Wealth 36:67–82, 1990) and deals with them by drawing on Haavelmo’s (A study in the theory of investment, Chicago: The University of Chicago Press, 1960) suggestions regarding the aggregation of capital. Among other findings, it turns out that the simulation results are highly robust, thus demonstrating that real-world implications may be even stronger than strictly suggested by the model.

Environmental liability and the capital structure of firms

This paper analyses the impact of environmental liability regimes on the capital structure of firms. We show that imposing environmental liability only on polluting firms, with limited liability, increases use of bank debt. Extending environmental liability to banks lowers bank borrowing relative to liability only on firms, with an ambiguous effect relative to no liability. Using US industry-level data we estimate a reduced-form model of bank borrowing by firms and show that the introduction of environmental liability only on firms increased bank borrowing by 15–20%, but when liability was extended to banks, borrowing returned to a level slightly higher than with no liability.     

Real options and contingent convertibles with regime switching

We consider a firm with no assets in place but an option to invest in a project. The investment is irreversible but delayable in a regime-switching economy. The firm issues equity, straight bonds (SBs) and contingent convertibles (CoCos). We provide the closed-form prices for the firm׳s securities and the pricing and timing of the option. Our numerical analyses discover that issuing CoCos instead of SBs induces much less agency cost of debt. The agency cost is higher in a boom economy than in recession but the difference is small. There is a unique CoCos׳ conversion ratio such that the agency cost arrives at the minimum value zero. The inefficiencies arising from asset substitution and debt overhang are much more significant in recession than in boom. Only if the conversion ratio is not too small, the two inefficiencies disappear during boom periods. While the effects of the conversion rate on optimal capital structure and firm value and those of supervision and jump intensity on optimal CoCos׳ coupon are ambiguous and weak, the stricter the supervision or the longer the economy remains in recession, the less the option value and the optimal SBs׳ coupon.     

Central bank disclosure as a macroprudential tool for financial stability

The Basel Capital Accord (pillar 3) states that disclosure of information (transparency) is essential to financial stability. This study analyzes, through inflation reports, the disclosure of information from the Central Bank of Brazil concerning the credit market. We consider credit risk and capital buffers as measures of financial stability in this analysis. Furthermore, in order to measure the perception of the monetary authority on the credit market, we built two indices based on the central bank’s communication on credit development. We performed a panel data analysis based on a sample of 125 banks for the period from June 1999 to September 2014 (7000 observations). The findings suggest that central bank communication regarding expectations concerning the credit market contributes to financial stability. Therefore, this kind of communication of central banks (about credit development) may constitute an important macroprudential tool to improve financial stability.     

External constraints and endogenous growth: Why didn't some countries benefit from capital flows?

Empirical evidence on the growth benefits of capital inflows is mixed. The growth benefits accruing from capital inflows also appear to be larger for high savings countries. We explain this phenomenon using an OLG model of endogenous growth in open economies with borrowing constraints that can generate both positive and negative growth effects of capital inflows. The amount an economy can borrow is restricted by an endogenous enforcement constraint. In our setting, with physical capital and a pay-as-you-go pensions system, the steady state is unique. However, it can either be constrained or unconstrained. In a constrained economy, opening up to equity and FDI inflows can be bad for growth because it makes the domestic interest rate too low, which endogenously tightens borrowing constraints. Agents decrease savings and investment in productivity-enhancing activities resulting in lower growth. Results are reversed in an unconstrained economy. We also provide a quantitative analysis of these constraints and some policy implications.     

Assessing the Impacts of Capital Inflows on Domestic Economy across the Sub-Saharan Africa Countries

Using GMM models, this paper analyzes the impacts of capital inflows on domestic investment in 44 Sub-Saharan Africa (SSA) countries from 2003–2012. It is found that foreign direct investment across the SSA remains to be the largest percentage share, accounting for 35% of the total capital inflows. FDI inflows have significant positive impacts on domestic investment across the SSA in both short term and long term. Other key macroeconomic factors such as age dependency ratio, domestic economic growth, terms of trade, real effective exchange rate and trade openness also play vital roles in determining domestic investment.     

股权结构影响下的上市公司融资倾向研究

本文选取深沪两市的900家上市公司为样本,以2001-2004年的财务及相关数据为基础,从我国上市公司特殊的股权结构出发,运用一般描述性统计分析、偏相关分析、独立样本T检验等方法,分析我国上市公司股权结构与融资倾向之间的关系,以探究在相同市场环境中,不同的股权结构安排是否会导致其融资倾向的差异性。研究结果表明,股权结构对上市公司融资倾向具有显著的影响,不同股权结构安排下的公司有不同的融资倾向,特殊的股权结构是造成我国上市公司融资结构不合理的主要因素。     

中国消费率和投资率的合理性判断：1978-2005

无论从国际比较,还是从对中国资本生产率以及增量资产产出率的分析来看,中国消费率显著低于国际水平,而投资率显著高于国际水平,且偏低的消费率与偏高的投资率存在着明显的不协调。     

Domestic financial market frictions,unrestricted international capital flows,and crises in small open economies

Summary. We present an example of a small open economy where small increases in the world interest rate may induce a sharp decline in output and a precipitous depreciation of the exchange rate. Due to a costly state verification problem in domestic credit markets, combined with unrestricted international capital flows, our economy generates two long-run equilibria, one with low GDP and a relatively depreciated real exchange rate (RER), and one with high GDP and a relatively appreciated RER. The first is always a saddle, while the second may be a sink or a source, depending on the level of the world interest rate. A crisis is identified with the economy switching from an equilibrium path approaching the high-output steady state to the saddlepath approaching the low-output steady state. In Mexicos recent history, periods of growth associated with appreciation of the RER have alternated with periods of sharp contraction and depreciation of the RER. Our economy displays such behavior in response to changes in the world interest rate.Received: 9 April 2002, Revised: 20 March 2003JEL Classification Numbers: E5, F4.G. Antinolfi, E.
