Industrialization, Economic Growth, and International Trade

This paper analyzes the relationship between economic growth, industrialization, and international trade in a two-sector endogenous growth model. With learning-by-doing, the economy grows perpetually along a balanced growth path, with manufacturing's relative price declining continuously. Under trade, its pattern of trade and growth will be affected by external growth. If it remains diversified under trade, its growth can keep in pace with the rest of the world. If the growth rate of the rest of the world is higher than a certain limit, the economy cannot catch up and will eventually produce agriculture only.     

MARKET POWER,PRICE ADJUSTMENT,AND INFLATION*

We study a monetary search economy in which endogenous fluctuations in market power driven by changes in consumers' search intensity determine the extent of price adjustment to movements in productivity and the money growth rate. A calibrated version of the economy exhibits countercyclical fluctuations in markups and is consistent with the observed incomplete response of nominal prices to cost movements associated with productivity fluctuations and to changes in the money growth rate. Furthermore, a higher average rate of inflation results in a lower average markup and increases the sensitivity of prices to fluctuations in either productivity or money growth.     

Neoclassical Growth, Manufacturing Agglomeration, and Terms of Trade

This study reverses the prediction of geography and growth models that trade integration may cause income divergence. Moreover, a new dynamic welfare gain of trade openness is identified. These results are obtained from embedding a new economic geography model into a neoclassical growth model. Starting from symmetric countries, a country that accumulates more capital than the other increases its home market size, improves its terms of trade, and lowers its relative consumption price index, because trade costs drive a wedge in between relative producer and consumption price indices. Both effects in turn tend to increase its marginal revenue product of capital relative to the other country (divergence forces), while factor substitution diminishes its marginal revenue product of capital (convergence force). Reducing trade costs decreases the wedge and weakens the divergence forces, while the convergence force is unaffected. Hence, divergence is more likely with higher rather than lower trade costs.     

Oil dependency of the Russian economy: An econometric analysis

A macro econometric model of the Russian economy is tailored to analyze the effects of changes in the oil price and alternative fiscal policies. Model simulations indicate that the Russian economy is vulnerable to large fluctuations in the oil price, but we also find evidence of significant economic growth capabilities in the absence of oil price growth. A higher oil price not only leads to higher economic growth and savings in the sovereign wealth fund, but also induces a rupture in the Russian economy. Public spending and household spending increase while the traditional export industries suffer from real appreciation, in line with the Dutch disease hypothesis. We also show that alternative policies for spending of the petroleum income may have considerable consequences for economic growth, the degree of crowding out of traditional export industries and wealth accumulation in the fund.     

Federalism,Fertility, and Growth

This paper analyses the effect of federalism on fertility and growth. In a model with human capital accumulation and endogenous fertility, two regimes of education finance are compared: central and local. I find that local education finance yields higher growth at the price of increased inequality. The effect of federalism on total and differential fertility rates depends on the elasticity of substitution between children and consumption. The paper also empirically examines the relationship between fertility rates and fiscal decentralisation on a panel of OECD countries and finds a weak negative effect of decentralisation on total and differential (poor minus rich) fertility.     

要素空间优化、宏观经济增长与物价稳定

确保经济长期平稳增长和物价持续稳定往往是传统财政政策和货币政策难以兼顾的预期目标.经济事实,尤其是最近一年"过山车"式的国内外经济形势告诉人们,高通货膨胀压力与高经济增长、通货紧缩威胁与经济衰落总是如影随形.经济一旦衰落就很难恢复,高通胀预期一旦形成,就很难使其下降.由此形成了系列"两难"困境,并使宏观调控趋于无效或低效.为摆脱这种困境,文章从空间视角下提出空问优化理论.研究发现,在空间优化理论指导下,运用空间优化政策能解决这种"两难"问题.这将为宏观调控在运用财政政策和货币政策解决实际经济问题时,提供了崭新的政策选择.     

Partial inflation indexation and long-run inflation targeting in a growing economy: A comparison of Calvo and Rotemberg pricing models

The observed 2% long run inflation target in most developed industrial nations is in variance with the zero or negative optimal inflation rates predicted by prominent monetary theories. Using a calibrated simple New-Keynesian model with endogenous growth and nominal rigidity, we compare two price setting environments of Calvo (1983) and Rotemberg (1982). In our growth model, the steady state welfare maximizing inflation takes into account the growth effect as well as the price distortionary effects of inflation. The long-run welfare maximizing trend inflation could be positive in economies with nominal rigidity in the form of partial inflation indexation and price stickiness. A higher degree of inflation indexation lowers the steady state price distortion in the Calvo model and steady state price adjustment cost in Rotemberg model and raises the long run optimal inflation. Since the productive inefficiency caused by partial inflation indexation is higher in Calvo economy compared to Rotemberg, the long run optimal trend inflation is higher in Rotemberg than in Calvo. In both models, a two percent long run inflation target is attainable for a reasonable degree of inflation indexation.     

Do commercial real estate prices have predictive content for GDP?

Using a uniquely compiled database concerning rental prices of commercial real estates, which are property of the largest broker in the Netherlands, we examine whether these prices have predictive value for quarterly economic growth. In contrast to related studies, we document that the mean price contains no relevant information, whereas other properties of the price distributions have. We show that these distributions can be described by mixtures of two distributions, reflecting low-end and high-end price segments. Our main findings are that higher economic growth is predictable from more new buildings being rented, more variation in the price levels and a larger size of the low-price segment, while lower economic growth emerges when the differences in prices between high-end and low-end segments increase and when the average price level in the low-price segment increases.     

Is there a quality bias in the Canadian CPI? Evidence from microdata

Rising consumer prices may reflect shifts by consumers to new higher‐priced products, mostly for durable and semi‐durable goods. I apply Bils’ (2009) methodology to newly available Canadian consumer price data for non‐shelter goods and services to estimate how price increases can be divided between quality growth and price inflation. I find that less than one third of observed price increases during model changeovers should be attributed to quality growth. This implies overall price inflation close to inflation measured by the official index. I conclude that, according to Bils’ methodology, the quality bias is not an important source of potential mismeasurement of CPI inflation in Canada.     

Gradual Product Replacement,Intangible-Asset Prices and Schumpeterian Growth

The paper develops a general-equilibrium model of scale-invariant Schumpeterian (R&D-based) growth. New higher-quality products are discovered through stochastic and sequential R&D races in each industry. The market share of an R&D race winner increases gradually and is governed by an exponential deterministic process. The introduction of gradual (as opposed to instantaneous) product replacement sheds more light on the effects of the rate of technology diffusion on long-run growth and on long-run dynamics of intangible asset prices. An economy with faster product diffusion rates experiences higher long-run innovation rates, faster transitional growth, and is populated by younger firms. As the typical firm becomes older, the earnings yield (i.e., the inverse of the price earnings (P/E) ratio) increases and expected earnings growth declines. Younger firms have lower earnings, lower market shares, but higher P/E ratios and higher expected earnings growth associated with their higher potential market growth.An electronic version of the paper is available at http://bear.cba.ufl.edu/dinopoulos/research.html.     

Price Indexes for US Medical Care Spending, 1980–2006

We construct price indexes for medical care spending in the US economy for the period 1980–2006. Our indexes show slower price growth than the official deflator from 1987–2001, consistent with the fact that indexes that improve on the official statistics typically find slower price growth than the official indexes. However, the result is reversed for the 2001–2006 time period. We develop a decomposition that parses out the numerical differences in these indexes into three factors that are held constant in the official price indexes but are not in our indexes: changes in the type of provider supplying care, changes in the type of insurance plan used by the patients, and changes in the bundle of procedures used to treat patients. Our results suggest that using the official price measures may provide misleading conclusions about spending trends and productivity growth in this important sector over this time period.     

Income Distribution and Demand-Induced Innovations

We introduce non-homothetic preferences into an innovation-based growth model and study how income and wealth inequality affect economic growth. We identify a (positive) price effect—where increasing inequality allows innovators to charge higher prices and (negative) market-size effects—with higher inequality implying smaller markets for new goods and/or a slower transition of new goods into mass markets. It turns out that price effects dominate market-size effects. We also show that a redistribution from the poor to the rich may be Pareto improving for low levels of inequality.     

Third-degree price discrimination,quality choice,and welfare

Employing an endogenous quality choice model, we reconsider the effect on welfare of monopolistic third-degree price discrimination. We prove that price discrimination always enhances welfare, mainly because the quality improvement owing to price discrimination increases consumer surplus. Moreover, we show that third-degree price discrimination benefits all parties, including consumers in the higher priced market if the preference differences between markets are sufficiently large.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

Inflation,oil price volatility and monetary policy

In a fully micro-founded New Keynesian framework, we characterize an analytical relationship between average inflation and oil price volatility by solving the rational expectations equilibrium of the model up to second order of accuracy. The model shows that higher oil price volatility induces higher levels of average inflation. We also show that when oil has low substitutability in the production function, the higher the weight the central bank assigns to inflation in the policy rule, the lower the level of average inflation is. The analytical solution further indicates that, for a given level of oil price volatility, average inflation is higher when marginal costs are convex in oil prices, the Phillips Curve is convex, and the degree of relative price dispersion is higher. The evolution of inflation during the 70s and 80s is consistent with the prediction of the model.     

Lagging productivity growth: Measurement,technology, and shock effects

One of the most important problems about which economists have professional knowledge is lagging productivity growth. After illustrating some significant developments this paper addresses three questions: (1) To what extent does R&;D activity drive productivity growth, (2) how do alternative measures of productivity affect the conclusions and (3) how did the oil price shocks and the increased openness of the U.S. economy affect productivity growth? After removing the influence of the extremely dynamic computer industry, average manufacturing industry productivity in the U.S. throughout the 80s grew at a disappointing pace. And it didn't improve in the most dynamic industries. But there is good news as well. First, part of the 1970s productivity slump is clearly attributable to the 1973–74 oil price shock. Second and more important, technological innovation does not appear to have lost its power in driving productivity growth forward. Indeed there is evidence of stronger and more consistent productivity effects from R&;D investment during the 1980s, although the exact channels through which R&;D enhances manufacturing sector productivity are left in doubt. Estimates of the role inter-industry technology flows play are sensitive to aggregation and the conventions used to construct the industry price deflators underlying productivity measures.     

Structural transformation and the oil price

What part of the high oil price can be explained by structural transformation in the developing world? Will continued structural transformation in these countries result in a permanently higher oil price? To address these issues I identify an inverted-U shaped relationship in the data between aggregate oil intensity and the extent of structural transformation: countries in the middle stages of transition spend the highest fraction of their income on oil. I construct and calibrate a multi-sector, multi-country, general equilibrium growth model that accounts for this fact by generating an endogenously falling aggregate elasticity of substitution between oil and non-oil inputs. The model is used to measure and isolate the impact of changing sectoral composition in the developing world on global oil demand and the oil price in the OECD. I find that structural transformation in non-OECD countries accounts for up to 53% of the oil price increase in the OECD between 1970 and 2010. However, the impact of structural transformation is temporary. Continued structural transformation induces falling oil intensity and an easing of the upward pressure on the oil price. Since a standard one-sector growth model misses this non-linearity, to understand the impact of growth on the oil price, it is necessary to take a more disaggregated view than is standard in macroeconomics.     

Technical change,employment, and supply response of agriculture in the Nile Delta: A system-wide approach

In this paper, a system-wide model of crop production in the Delta region is developed in order to comprehensively analyze Egyptian agricultural policies and also to identify the main causes of the slow growth of the sector in the seventies. Previous studies based on single-crop models have blamed the government's price policies as the culprit. Our estimation results show that although there might have been some gains from appropriate changes in the relative prices of crops, price policies in general were not responsible for the poor performance of the sector, since the aggregate supply response of crops to the price levels in indeed quite low. The main factor which seems to explain the slow growth of agriculture is the decline in the level of investment in irrigation and drainage. Investment in land reclamation, on the other hand, has had negative effects on the short-run growth of the sector. On the question of the impact of increased mechanization on Egyptian agriculture, we find that mechanical power has essentially displaced animals in crop production without much affecting the growth rate of the sector or its employment opportunities directly.     

Fairness, price stickiness, and history dependence in decentralized trade

The paper investigates price formation in a decentralized market with random matching. Agents are assumed to have subdued social preferences: buyers, for example, prefer a lower price to a higher one but experience reduced utility increases below a reference price that serves as a common fairness benchmark. The strategic equilibrium reflects market fundamentals, but it is markedly less sensitive to the buyer–seller ratio near the fair price benchmark. Prices may be sticky around very different reference levels in markets with otherwise identical fundamentals. The implied history dependence turns out to be mitigated rather than exacerbated by friction.     

Technological Progress, Downsizing and Unemployment

This paper presents a model where the form of innovations is endogenous. It is shown that with labour market imperfections, which raise the wage above the shadow price of labour, firms over-invest in innovations cutting labour costs and under-invest in increasing quality. As a result, the market outcome features lower long run growth, higher unemployment and lower welfare than the social optimum. It is further shown that a firm's incentives to cut labour costs are increased as wages rise and as the firm declines. Finally, a rise in competition increases incentives to downsize for firms with below average quality performance.
