Endogenous insecurity and economic development

We explore the implications of endogenous credit market imperfections for the endogenous relationship between investment insecurity and the process of economic development. In the initial stages of development, the fraction of agents engaged in nonproductive diversionary activities (e.g. rent-seeking) grows as the opportunities to gain from diversionary activities expand. In later stages, however, diversion falls as capital market imperfections are overcome and productive activities become more secure and more profitable. We detail the forces that determine whether the insecurity generated by an economy's early development will choke off the growth process. We also compare the cost-effectiveness of alternative policies designed to prevent diversion.     

Sectoral Changes in Employment: An eclectic perspective on ‘good’ jobs and ‘poor’ jobs

The linkage Keynes established between the volume of employment that business firms require to make a particular number of jobs available provides an operational perspective about the way in which labor markets work. The aggregate supply or Z function is, in fact, a job offer curve. The most significant insight to derive from this curve is that job offers are inseparable from the economy's aggregate expenditure (or demand) level. This interdependency of aggregate supply and aggregate demand is necessary to understand the functioning of labor markets in the real world. This paper argues that a disaggregated model which encapsulates the economy's price-taking and price-making sectors offers a promising analytical tool to gain perspective about ‘good jobs’ and ‘poor jobs’ in post-Fordist economies. It is maintained that the sectoral deployment of workers reflects whether employing firms, as price-makers, can capture the increasing returns inherent in modern technology.     

Investment and deposit contracts under costly intermediation and aggregate volatility

This paper examines how volatility affects investment and the form of deposit contracts in a three-period model where capital formation is financed by bank credit and lenders face state verification and enforcement costs. Firms face both idiosyncratic and aggregate shocks, and agents are initially risk neutral. We show that intermediation costs magnify the incidence of macroeconomic volatility on banks' expected losses and have an adverse effect on investment. With risk-averse consumers, the impact of banks' expected losses on investment is mitigated because the equilibrium deposit contract provides partial insurance against adverse macroeconomic shocks.     

Median‐voter Equilibria in the Neoclassical Growth Model under Aggregation*

We study a dynamic version of Meltzer and Richard's median‐voter model where agents differ in wealth. Taxes are proportional to income and are redistributed as equal lump‐sum transfers. Voting occurs every period and each consumer votes for the tax that maximizes his welfare. We characterize time‐consistent Markov‐perfect equilibria twofold. First, restricting utility classes, we show that the economy's aggregate state is mean and median wealth. Second, we derive the median‐voter's first‐order condition interpreting it as a tradeoff between distortions and net wealth transfers. Our method for solving the steady state relies on a polynomial expansion around the steady state.     

Credit in Times of Stress: Lessons from Latin America during the Global Financial Crisis

The 2008–2009 global financial crisis disrupted the provision of credit in Latin America less than in previous crises. This paper tests whether specific characteristics at both the bank and country levels at the onset of the global crisis contributed to the behavior of real credit growth in this region during the crisis. As shown, financial soundness characteristics of Latin American banks, such as capitalization, liquidity, and bank efficiency in the pre‐crisis period, played a role in explaining the dynamics of real credit during the crisis. We also found that foreign banks and banks that had expanded credit growth more before the crisis were also those that cut credit the most. Among country‐specific characteristics, we found evidence that balance sheet measures such as the economy's overall currency mismatches and external debt ratios (measuring either total debt or short‐term debt) were key variables in explaining credit growth resilience.     

A demand and supply analysis of productivity growth

The paper rejects growth accounting as failing to reveal the economic forces that drive growth. Instead, it seeks to explain changing productivity growth in terms of economic phenomena such as the changing structure of output, the rate of adoption of new technology, and the strength of aggregrate demand. We introduce such a model and test it using pooled cross section and time series data for 16 OECD economies over a 30 year period. The parameter estimates allow us to decompose each economy's productivity growth into the part caused by its changing structure and the part explained by demand conditions. The estimates are used to account for the productivity slowdown that occurred in these economies after 1973, and to examine the recent productivity increase in the US. The model fully explains this growth surge in terms of the changed demand factors and structure of the US economy. We conclude by arguing that a prime benefit of strong aggregate demand is its stimulation of investment and technological change, leading to the adoption of new technology on a broad front.     

SOCIAL STATUS AND THE GROWTH EFFECT OF MONEY*

It has been shown that in a standard one‐sector AK model of endogenous growth with wealth induced preferences for social status, the economy's growth rates of real output and nominal money supply are positively related when the cash in advance constraint is applied solely to the household's consumption purchases. However, a positive output growth effect of money/inflation is not consistent with the existing empirical evidence. We show that when gross investment must be financed by real money balances as well, this result is overturned, i.e. higher inflation is detrimental to economic growth, because of a dominating portfolio substitution effect.     

Credit Availability and Capital Crunch: On the Role of the Heterogeneity of the Banking System

We analyze the impact of a credit crunch on aggregate investment via the heterogeneous structure of the banking system. We develop a model of endogenous credit allocation in which investors and two banks differ according to their level of capital and monitoring technology. In a context of moral hazard problem, we show that banks' cost advantage in the monitoring of small businesses must be compared to their relative amount of capital in order to explain firms' optimal choice of financing, the credit allocation in the economy and the asymmetric impact of a credit crunch on aggregate investment. A shock of the same magnitude on the two banks level of capital may have a different effect on total investment. We stress that the credit crunch is maximum when the shock hits the bank specialized in the financing of small businesses and when this bank is also the less capitalized. This result is supported by recent empirical studies ( Hancock and Wilcox 1998 ).     

Self-serving dictators and economic growth

We study the effect of fair institutions on growth. In our model, individuals are endowed with unequal entitlements to the economy's output. They can free-ride or cooperate. Cooperation is individually costly, but increases aggregate output and growth. Experimentally, we observe significantly less cooperation, when dictators chose high instead of low inequality. This effect is not observed when the degree of inequality is chosen randomly. Simple cross-country regressions provide basic macroeconomic support for interaction effects between the degree and the genesis of inequality. We conclude that economies granting equal opportunities are less likely to suffer retarded growth due to free-riding than economies with self-serving dictators.     

SLOW DEVELOPMENT AND SPECIAL INTERESTS*

This article argues that a natural implication of an innovation‐based theory of growth is that slow development facilitates the formation of special interest groups. We demonstrate this in a growth model where innovations take the form of new goods and new production processes, and where factor suppliers in individual industries can organize to form rent‐extracting special interest groups. We then examine the effect these groups have on an economy's subsequent development. We find that these groups can retard an economy's development for extended periods, but not permanently. Their long‐run effect is to increase the volatility of the development process.     

TIME‐VARYING UNCERTAINTY AND THE CREDIT CHANNEL

We extend the Carlstrom and Fuerst (American Economic Review, 1997, 87, pp. 893–910) agency cost model of business cycles by including time‐varying uncertainty in the technology shocks that affect capital production. We first demonstrate that standard linearization methods can be used to solve the model yet second moments enter the economy's equilibrium policy functions. We then demonstrate that an increase in uncertainty causes, ceteris paribus, a fall in investment supply. We also show that persistence of uncertainty affects both quantitatively and qualitatively the behaviour of the economy.     

Equity market information and credit risk signaling: A quantile cointegrating regression approach

Investigating linkages between credit and equity markets, we consider daily aggregate U.S. CDS spreads as well as well-chosen equity market and implied volatility indexes over ten years. We describe such robust (to spurious correlation) relationship with the quantile cointegrating regression approach. Such approach handles extreme quantiles/CDS values and their behavior with respect to the equity market's influence. Heteroskedastic patterns such as time-varying variance, but also autocorrelation, skewness and leptokurtosis are captured. Thus, the sensitivity of aggregate CDS spreads to equity market price and volatility channels is accurately measured across quantiles and spreads. Such quantile-dependent sensitivity exhibits asymmetric responses to equity market shocks. A sub-period analysis investigates potential regime shifts in estimated quantile cointegrating regressions. Quantile cointegrating coefficients vary over time and quantiles, and exhibit different magnitudes across sub-periods and spreads. Therefore, the relationship is unstable over time. We also propose a scenario analysis and risk signaling application for credit risk management prospects. Under specific risk levels, credit risky situations are described conditional on the equity market's information over time, and related expected aggregate CDS spreads are computed. Estimated conditional quantiles/CDS spreads act as credit alert triggers.     

FUNCTIONAL ESTIMATES OF JAPANESE GOVERNMENT DOMESTIC EXPENDITURES, FISCAL 1952–1963

The purpose of the paper is to describe current and constant price estimates of Japanese central and local government postwar domestic expenditures by economic type and function recently completed by Miss Yoshiko Kido, International Christian University, Tokyo, and myself. The rationale of the functional classification is to estimate those government expenditures which enhance the economy's productive capacity. Expenditures are divided into four broad functional categories: developmental, disaster repair and prevention, social welfare, and general government. These four categories are subdivided to two levels of disaggregation. We were able to break down government fixed investment, government enterprise inventory investment, current domestic transfers and subsidies into 42 functional components. For constant price series, each functional component by economic type was deflated by separate price indexes. We followed the Economic Planning Agency's procedure for the official national accounts of assuming no productivity change in the provision of government services. Our results are generally comparable to the official national accounts estimates. The major difference is that we attribute considerably more fixed investment to local governments, and correspondingly less to the central level. Government expenditures had the following characteristics. Growth was rapid; in real terms the public sector use of the economy's resources in 1963 was 2.2 times more than in 1952. The elasticity of government expenditures to GNP was unity in current prices, slightly less in real terms. The government postwar share in GNP has been smaller than in European nations and, unlike them, was not rising. This reflects the underlying growth strategy of emphasis upon private business fixed investment. Government consumption expenditures declined relative to GNP, and investment rose. Developmental expenditures comprised the largest share (40–45 per cent) of the government total. The elasticities to GNP of government expenditures by economic and functional categories are provided and discussed. A simple test was made of the cyclical relationship of government expenditures (both total and by category) to GNP. The results suggest that government expenditures, rather than contra-cyclical, were pro-cyclical in effect.     

International Adjustment With Habit-Forming Consumption: A Diagrammatic Exposition*

This paper presents a simple diagrammatic analysis of an open economy's external adjustment process under habit-forming individual preferences. the exposition focuses on the consumption side and alms to make transparent the linkage among wealth, past consumption experience, and current consumption. an extension of the standard representative-agent model to a growing economy of overlapping generations completes the paper. Under habit formation an agent's consumption exhibits a form of hysteresis, in that his current consumption depends on his past consumption experience as well as initial assets. In the overlapping-generations model aggregate hysteresis disappears in the long run.     

Why progressive redistribution can hurt the poor

Recent macroeconomic research discusses credit market imperfections as a key channel through which inequality retards growth: With convex technologies, progressive transfers increase aggregate output because marginal returns become more equalized across investment opportunities. We argue that this reasoning may not hold in general equilibrium. Since the investment functions are concave in wealth, reducing inequality increases capital demand and the interest rate. Hence, through the impact on capital costs, shifting wealth from the rich to the middle class depletes the poorest investors' access to credit. But because the poor face the highest marginal returns, the net effect on output may be negative. We find, however, that redistributing towards the bottom-end of the distribution has a clear positive impact. Finally, we discuss the implications of our theoretical findings for future empirical research.     

Innovation Shortfalls

There is a common perception that low productivity or low growth is due to what can be called an “innovation shortfall,” usually identified as a low rate of investment in R&D. The problem with this analysis is that it fails to see that a low R&D investment rate may be appropriate given the economy's pattern of specialization, or may be just one manifestation of impediments to accumulation more generally. This paper first shows a simple way to estimate the R&D gap that can be explained by a country's specialization pattern, illustrating it for the case of Chile. Second, we show how a calibrated model can be used to determine the R&D gap that should be expected given a country's investment in physical and human capital. If the actual R&D gap is above this expected gap, then one can say that the country suffers from a true innovation shortfall.     

The Structure of the American Economy

We explore the relationship between input–output accounts and the national revenue function. The generalized inverse of an economy's technology matrix carries information relating changes in endowments with changes in outputs; its transpose relates output prices and factor prices. Our primary theoretical contribution is to derive an economy's revenue function for an arbitrary Leontief technology. Our main empirical contribution is to compute the national revenue function for the American economy in 2003 and to describe its properties. We implement our ideas using two different models: one where all factors are mobile and another with sector‐specific capital.     

Economic Development and the Relative Price of Nontradables: Global Dynamics of the Krueger-Deardorff-Leamer Model*

This paper employs a three-factor model of economic development to model forward-looking nontraded investment as a determinant of the relative price of nontradables. A capital-intensity. reversal of nontraded output relative to manufactured output-arising from a switch toward a capital-intensive manufacturing technique from a labor-intensive technique-produces a bifurcation in the model's dynamics. the two resulting saddlepath trajectories are each consistent with optimizing behavior and transversality conditions at infinity. History, as embodied in the economy's capital stock, as well as forward-looking expectations determine whether the economy chooses the low-investment or high-investment trajectory.     

The Carbon Bubble: climate policy in a fire-sale model of deleveraging∗

Credible implementation of climate change policy, consistent with the 2 °C limit, requires a large proportion of current fossil-fuel reserves to remain unused. This issue, named the Carbon Bubble, is usually presented as a required asset write-off, with implications for investors. We embed the Carbon Bubble in a macroeconomic model exhibiting a financial accelerator: if investors are leveraged, then the Carbon Bubble might precipitate a fire-sale of assets across the economy, and generate a large and persistent fall in output and investment, impairing the economy's ability to invest in the zero carbon assets it needs to produce output in the post-climate-transition world. We find a role for macroeconomic policy protecting investors' balance sheets in mitigating the macroeconomic effects of the Carbon Bubble, and enhancing welfare.     

Government Expenditure Financing in a Two‐Sector Cash‐In‐Advance Model of Endogenous Growth

We show that an expansion in the government size could be desirable from the viewpoint of the economy's long‐run growth, wherein factor intensity between the sectors, the mode of public spending financing, and the form of the cash‐in‐advance (CIA) constraint are crucial. We also show that when real balances are required only for consumption purchases, money financing is equivalent to consumption tax financing, but is not equivalent to income tax financing. If both consumption and gross investment are liquidity‐constrained, then the three financing methods are mutually not equivalent. The optimal financing scheme has the following features: (1) when the CIA constraint applies only to consumption purchases, any combination of the money growth rate and the consumption tax rate that satisfies the government budget constraint constitutes an optimal financing mix; (2) when the CIA constraint applies to both consumption and investment purchases, consumption tax financing only is optimal.
