Natural resources,technological progress,and economic modernization

The present inquiry focuses on the modernization perspectives of the commodity‐exporting countries through the lens of development economics. To this end, the study adopts the Kaldorian framework to address the modernization effects, epitomized in the absorption of surplus labor. To trace the process of economic modernization, the study augments Lewis’s dualistic economy model by the extractive sector. Three different scenarios for the management of resource revenues are scrutinized. An altruistic mode, which implies a pure redistribution of the revenues among the poor swaths of the population, protracts the process of economic modernization, requires a greater amount of capital stock, and harbors a greater risk of a poverty trap. This effect is less pronounced if the modern sector is more capital‐intensive. A productive mode, which elicits full reinvestment of the commodity revenues, in contrast, accelerates the pace of economic modernization. Further, predicated on the scrutiny of a more realistic scenario, a bargaining mode, the study derives the condition for a net positive (or negative) modernization effect. The study identifies technical progress alongside capital accumulation as a further important source of economic modernization.     

The “Dark Side” of Deregulation: How Competition Affects the Size of the Shadow Economy

This paper builds a theory that explains the dramatic expansion of the underground economy in the late 1990s by the sharp increase in market competition worldwide. I model an oligopoly game where firms first decide on entry and sector, and then compete in price. Operating in the underground sector reduces variable costs, but comes at the risk of being detected and fined. As competition intensifies (i.e., as consumers become more and more price‐sensitive), underground firms attract more demand, thus stealing business and profits from official firms. As a consequence, more firms enter the underground economy. A lenient policy toward the underground economy may increase welfare when markups are high, but will be welfare‐detrimental when markups are low.

Banking firm and hedging over the business cycle

This paper examines the behavior of a banking firm under risk. The banking firm can hedge its risk exposure by trading futures contracts. The banking firm is risk averse and possesses a utility function defined over its end-of-period income and a state variable that denotes the business cycle of the economy. We show that the banking firm optimally opts for an over-hedge or an under-hedge, depending on whether the returns on the futures contracts are negatively or positively correlated with the business cycle of the economy, respectively. Thus, the business cycle of the economy is an important determinant in shaping the banking firm’s optimal hedging strategy.     

FINANCIAL MARKET INTEGRATION AND BUSINESS CYCLE VOLATILITY IN A MONETARY UNION

This paper uses a dynamic general equilibrium two‐country sticky‐price model to analyze the implications of financial market integration for the propagation of asymmetric productivity and government spending shocks in a monetary union. Financial market integration has a small effect on the propagation of these shocks if households can only trade in risk‐free bonds. However, financial market integration has a more substantial effect on the propagation of these shocks in a monetary union with a complete market for state‐contingent claims. This result indicates that it may be important to account for threshold effects in empirical analyses of the impact of financial market integration on business cycle volatility in a monetary union.     

金融衍生品、市场失灵与数字化治理

金融衍生品市场分析的改进型IS-LM模型为我们提供了分析金融衍生品市场发展条件下虚拟经济对实体经济影响的框架,但很难有效地解决有关问题,更不能以此作为宏观决策的依据。金融衍生品市场作为一种特殊的市场形态,也会出现一般市场中经常出现的市场失灵现象,表现为金融市场上可能存在不完全竞争、负外部效应、信息不对称和公共物品等。需要引入电子商务,克服信息的不完全,建立起数字化风险预警系统,对金融衍生品市场风险防范于未然。

Information, the Dual Economy, and Development

We examine the interactions between different institutional arrangements in a general equilibrium model of a modernizing economy. There is a modern sector, where productivity is high but information asymmetries are large, and a traditional sector where productivity is low but information asymmetries are small. Consequently, agency costs in the modern sector make consumption lending difficult, while such lending is readily done in the traditional sector. The resulting trade-off between credit availability and productivity implies that not everyone will move to the modern sector. In fact, the laissez-faire level of modernization may fail to maximize net social surplus.
This situation may also hold in the long run: in a dynamic version of the model, a "trickle-down" effect links the process of modernization with reduction in modern sector agency costs. This effect may be too weak and the economy may get stuck in a trap and never fully modernize. The two-sector structure also yields a natural theoretical testing ground for the Kuznets inverted-U hypothesis: we show that even within the "sectoral shifting" class of models, this phenomenon is not robust to small changes in model specification.

Growth of business services: A supply‐side hypothesis

This paper aims to explain why and how the service sector may grow faster than manufacturing. It develops a two‐sector, closed‐economy model, having a manufacturing sector and a service sector. Accumulation of human capital serves as the basis of growth. The analysis focuses on business services, while household services are also considered. It is argued that differences in returns to scale between the two sectors and employment frictions in manufacturing explain why the growth rate of the service sector may be higher. The model also features that within the service sector the business services sub‐sector may grow faster than household services.     

Economic Progress,Social Regress?

A central issue in the debate regarding the relevance of social capital is whether the decline in social embeddedness that has attended modernization over the last 40 years in the United States is as harmful as Putnam, among others, claim it to be. Critics of Putnam's thesis argue that various arms‐length institutions fulfil the roles performed by social capital thereby mitigating the negative impact of its recent decline. We develop a framework that provides insight into when such institutions may be adequate and when they might not. We find that if market (economic) and non‐market (social) interactions differ in their payoffs but are interlinked through the modernization of the economy, the optimal level of modernization in market interactions will be higher than that in non‐market interactions. Further, market supporting institutions are likely to increase the divergence between economic and social interactions since analogs for market institutions that constrain opportunistic behavior are usually nonexistent in social contexts. In this sense, economic progress may be accompanied by social regress.     

Wage Flexibility and Unemployment: The Keynesian Perspective Revisited

Keynes' main concern in the General Theory is about the capacity of an economy to return to full employment equilibrium when subject to a (negative) demand shock. He maintains that money wages cuts may not help reabsorb unemployment, as they do not necessarily imply a fall in real wages. On the contrary, wage rigidity may be necessary for avoiding that a cumulative process propels the economy far away the full employment equilibrium. Co‐ordination failures in the investment‐saving market are behind this conclusion. However, the analysis is carried out within a static equilibrium framework. This paper is an attempt to focus on the problems of intertemporal co‐ordination arising within the context of a sequential economy. Our analysis of the out‐of‐equilibrium process of adjustment stirred by a shock allows to generalize the original Keynesian intuition. Unemployment emerges as the result of a lack of co‐ordination due to irreversibly constrained choices, and not only nominal but also real wage flexibility does not necessarily help to restore equilibrium. As a matter of fact, it may even be harmful, by triggering processes that make the economy diverge from equilibrium. Our analysis has important analytical implications as regards the role of market imperfections and the interpretation of the effects of monetary policy.     

MISERY LOVES COMPANY: EQUILIBRIUM PORTFOLIOS WITH HETEROGENEOUS CONSUMPTION EXTERNALITIES*

The present article extends the Arrow–Debreu portfolio model to consumption externalities. It is assumed that each investor has a von Neumann–Morgenstern utility that is a function of her own consumption and of the average consumption in the group to which she belongs. Individual degrees of risk aversion and conformism are heterogeneous within each group and between the different groups in the economy. We show that, under some conditions on the degree of conformism in the economy, the optimal portfolio and consumption choices observed at equilibrium in each group with consumption externalities are equivalent to those that are optimal without any externality, but with an adjusted degree of risk aversion. If these conditions are not fulfilled, groups have no representative agent and the demand for pure zero‐mean lotteries may be positive, thereby showing that not all diversifiable risks are washed away at equilibrium. We characterize the relationship between the distribution of conformism in the economy to the competitive allocation of risk and to the equity premium. We provide conditions for the two‐fund separation property to hold.

Shocks,learning, and persistence

A simple model of the process of learning in a diverse economy is presented. This model produces a stylized business cycle with shocks which precipitate the learning process. All agents have the same information, which implies that this business cycle cannot be reduced by improved information flow, counter to many models of output and employment fluctuation.     

Incomplete risk sharing arrangements and the value of information

Summary. The paper constructs a theoretical framework in which the value of information in general equilibrium is determined by the interaction of two opposing mechanisms: first, more information about future random events leads to better individual decisions and, therefore, higher welfare. This is the ‘Blackwell effect’ where information has positive value. Second, more information in advance of trading limits the risk sharing opportunities in the economy and, therefore, reduces welfare. This is the ‘Hirshleifer effect’ where information has negative value. We demonstrate that in an economy with production information has positive value if the information refers to non-tradable risks; hence, such information does not destroy the Blackwell theorem. Information which refers to tradable risks may invalidate the Blackwell theorem if the consumers are highly risk averse. The critical level of relative risk aversion beyond which the value of information becomes negative is less than 0.5. Received: May 14, 2001; revised version: March 5, 2002     

Residual Claims in Co‐operatives: Design Issues

This paper examines issues in the design of a co‐operative member's contractual relationship with the other agents (including the remaining members) using organizational economics. The paper assumes that the central defining characteristic of a co‐op is the residual claim specification. Agency theory identifies certain inherent problems of the co‐op form, the horizon problem, common property problem, and non‐transferability. Non‐transferability both reduces the incentive to monitor and imposes limits on portfolio diversification. This paper argues that features such as claim incompleteness and non‐transferability are not inherent to the co‐op but may be transaction‐cost economizing. The paper also argues that the pre‐emptive payoff feature by which the residual claimants (the co‐op members) also become fixed payoff agents can affect the risk of other agents, and is an important determinant of co‐op risk. A co‐op may have more than one potential residual claim base. Five generic design choices are available for handling possible multiple claim bases: battleground, pre‐specified allocation, limited return, alignment, and fixed payoff. The paper uses the design of residual claims in sugar co‐ops to show how a co‐op can partly overcome some of the problems identified by agency theory. This illustration ties together the issues of claim incompleteness and non‐transferability, pre‐emptive payoff, and multiple claim bases.

Mexico's Business Cycles and Synchronization with the USA in the Post‐NAFTA Years

A number of papers have investigated the increasing macroeconomic ties between Mexico and the USA. These studies have relied on linear models, however, making their results suspect. Other papers have investigated nonlinearity over the Mexican business cycle, but have not studied the links between the Mexican and US economies. In this paper a Markov‐switching model is employed to investigate the changing macroeconomic effect of the USA on Mexico. The findings show that the USA indeed appears to have a much larger impact since the passage of the North Atlantic Free Trade Association (NAFTA) than in previous years. Results also indicate that the level of foreign exchange reserves has much less predictive power for the Mexican economy since NAFTA. This suggests that the greater synchronization with the US business cycle may be more attributable to better macroeconomic management in Mexico than to the closer trade links.
