目前我国城镇基础设施投融资模式分析

在我国经济建设步伐加快,各级地方财政普遍吃紧的情况下,直接财政投资、土地储备制度等传统融资模式已不能满足城市基础设施融资的需求。继之出现的BOT、TOT、PFI、ABS和市政债券的投融资模式市场程度依次提高,共同的特点在于引入SPC作为桥梁将政府与市场在公共物品领域连接起来,这些融资模式合作形式各异,以公私合营和资本市场的力量为城建资金寻找到了更广泛的投资者。本文介绍了我国现行的城镇基础设施投融资模式,如土地储备制度和市政债券等,依市场化程度的高低对这些融资进行了分类分析和比较,指出未来我国城建融资模式的发展方向。     

Noisy signaling in discrete time

This paper characterizes the equilibrium set of a dynamic noisy-signaling model in discrete time. A seller privately knows the quality of her asset. She can exert a costly effort to generate stochastic returns. Buyers stochastically arrive over time and, after observing the history of returns, they make price offers. In our model, the equilibrium behavior of the buyers is discontinuous: they only make acceptable (high) offers if the posterior about the quality is above a given threshold. As a result, the recursive nature of the model replicates the discontinuity, giving the equilibrium continuation payoff a complex self-replicating structure that may take the form of a devil’s staircase.     

Capital maintenance and depreciation over the business cycle

This paper develops and estimates a stochastic general equilibrium model with capital maintenance, which affects endogenously the depreciation rate of capital. The estimate of maintenance series is found to track survey-based measures for Canada quite closely and to generate the procyclical pattern of maintenance observed in the data. We use our model estimates to infer the time profile of equipment capital depreciation in Canadian and US manufacturing. The depreciation rate is estimated to be volatile and highly procyclical in both countries.     

Is working capital management value-enhancing through alleviating financial constraints? Evidence from Chinese non-listed firms

Financial factors have been found highly important in influencing firms’ real activities and in promoting aggregate growth. Yet, the linkage between finance and firm-level total factor productivity (TFP) has been overlooked in the literature. I fill this gap using 147,310 non-listed Chinese firms over the period 1999–2007 to estimate a TFP model augmented with working capital. I find that TFP is strongly and significantly associated with working capital for private and foreign firms, but not for SOEs. More specifically, an increase in working capital has a negative (positive) effect on TFP in firms with positive (negative) working capital. Furthermore, highly external financial constrained, highly internal financial constrained, under-developed institutional regions and small size private and foreign firms are more sensitive to working capital.     

Multiple equilibria in the Aghion–Howitt model

We show that the simple Aghion–Howitt model exhibits oscillatory indeterminacy in the process of creative destruction as firms undertaking new research do not internalize their effect on existing firms. A simple calibration shows that indeterminacy occurs for quite plausible parametrizations of the share of the intermediate good.

A general endogenous grid method for multi-dimensional models with non-convexities and constraints

The endogenous grid method (EGM) significantly speeds up the solution of stochastic dynamic programming problems by simplifying or completely eliminating root-finding. We propose a general and parsimonious EGM extended to handle (1) multiple continuous states and choices, (2) multiple occasionally binding constraints, and (3) non-convexities such as discrete choices. Our method enjoys the speed gains of the original one-dimensional EGM, while avoiding expensive interpolation on multi-dimensional irregular endogenous grids. We explicitly define a broad class of models for which our solution method is applicable, and illustrate its speed and accuracy using a consumption–saving model with both liquid assets and illiquid pension assets and a discrete retirement choice.     

Endogenous ranking and equilibrium Lorenz curve across (ex-ante) identical countries: A generalization

This paper proposes a symmetry-breaking model of trade with a finite number of identical countries and a continuum of tradeable consumption goods, which differ in their dependence on nontradeable intermediate inputs, “producer services”. Productivity of each country is endogenous due to country-specific external economies of scale in its service sector. It is shown that, in any stable equilibrium, the countries sort themselves into specializing in different sets of tradeable goods and that a strict ranking of countries in per capita income, TFP, the service sector share, and the capital–labor ratio emerge endogenously. Furthermore, the distribution of country shares, the Lorenz curve, is unique and analytically solvable in the limit, as the number of countries grows unbounded. Using this limit as an approximation allows us to study what determines the shape of distribution, perform various comparative statics and to evaluate the welfare effects of trade. In doing so, this paper extends the analysis of Matsuyama (Econometrica, 81:5 (September 2013), 2009–2031) for more general and flexible forms of scale economies. It turns out that the technique introduced in Matsuyama (Econometrica, 81:5 (September 2013), 2009–2031) is useful for the equilibrium characterization in this general case as well. Although some results of comparative statics and on welfare inevitably need to be modified, they change in ways that illuminate the underlying mechanism of symmetry-breaking.

Corporate Cash Holding in Asia

In this paper, we analyze the determinants of corporate saving in the form of changes in cash holdings for 11 Asian economies using firm‐level data from the Oriana Database for the 2002–2011 period. We find some evidence that cash flow has a positive impact on the change in cash holdings (i.e. that the cash flow sensitivity of cash is positive) and that the positive impact of cash flow on the change in cash holdings is larger and more significant in the case of smaller and presumably more constrained firms than in the case of larger and presumably less constrained firms in both developed and developing economies. Both of these findings corroborate the importance of financial constraints in Asian firms. In addition, we find that the cash flow sensitivity of cash declined after the global financial crisis and that Tobin's q has a positive impact on the change in cash holdings, especially in the case of larger and presumably unconstrained firms.
