The top-dog and the lean and hungry look strategies in endogenous entry

This paper examines the strategic commitment behavior of heterogeneous leaders in an endogenous market structure. We demonstrate that each leader's investment level is independent of the other leaders' characters. Furthermore, we show that a leader over-invests (resp. under-invests) when an investment increases (resp. decreases) the leader's marginal profitability. Such an investment always makes leaders employ aggressive strategies in the competition relative to those in a no-commitment case. This result implies that aggressiveness of leaders is a robust observation in an endogenous market structure.     

Application of factor models for the identification of countries sharing international reference-cycles

Using the methodology developed in Stock and Watson (2002a), this paper proposes to exploit the information that contains the factor loading to identify the countries sharing common factors. The proposal is illustrated by analyzing the relation with the international reference-cycle of a large sample of advanced countries from 1950 until 2006.     

The implications for an open economy of partisan political business cycles: Theory and evidence

This paper develops and tests the predictions of two open economy models in which partisan effects are present, a small-country-one-good model of exchange rate determination and a model that assumes the two countries each specialize in the production of one good. From these models, we can obtain predictions for the behaviour of the terms of trade, the current account, and real and nominal exchange rates. The predictions are tested empirically using panel data from 14 OECD countries and the results provide support for the theoretical predictions that systematic partisan effects are present in current accounts, real exchange rates, and the terms of trade.     

Multi-country tests for the oscillator model with slowly varying coefficients

This paper applies Ramsey's (1992) forced oscillator model discovered with US data to Canada, Japan, UK, Belgium, France, Germany, and Italy. We also examine the aggregate production index for consumer goods in the US. Thus, the model is applied to and the results checked against data that were not involved in the discovery of the model in the original paper. The adequacy of the model is evaluated and international comparisons are made. The similarity of the estimates for all of the data sets examined suggest that the model may be widely applicable for consumer goods production indices, although France and Italy provide partial exceptions to this statement.     

Does a ‘non-committed’ government always generate lower social welfare than its ‘committed’ counterpart? Strategic trade policy when consumer surplus matters

We show that social welfare in the setup where the government lacks the full ability to commit to its trade policies may exceed the social welfare when the government possesses full commitment power if consumer surplus is part of the social welfare function. This is never the case in the standard, “third market” framework of strategic trade policy. We provide two examples in which consumer surplus matters: the “home market” and the “intra-industry trade” setup. The policy instruments under consideration are import tariffs and export subsidies and there are R&D spillovers from the domestic to the foreign firm.     

Exploiting old customers and attracting new ones: The case of bank deposit pricing

Recent theoretical contributions suggest that deposit interest rates should be higher in geographic areas characterized by greater in-migration and lower for depositors at banks with greater shares of existing (or so-called “locked-in”) depositors. These hypotheses are tested using a rich data set obtained for the Spanish banking industry. Results confirm that, all else equal, banks offer higher deposit rates in territories characterized by greater in-migration, and also that they tend to offer lower rates, the larger the number of their locked-in depositors. These findings confirm the existence of the trade-off between exploiting old customers and attracting new ones.     

Output gap measurement and the New Keynesian Phillips curve for China

The New Keynesian Phillips curve implies that the output gap, the deviation of the actual output from its natural level due to nominal rigidities, drives the dynamics of inflation relative to expected inflation and lagged inflation. This paper exploits the empirical success of the New Keynesian Phillips curve in explaining China's inflation dynamics with a new measure of the output gap. We estimate the output gap using the Bayesian multivariate Beveridge–Nelson decomposition method, based on a multivariate dynamic model featuring distinct interactions among inflation, money, and real output in China. The empirical results using quarterly data spanning 1979–2010 show that the new measure of the output gap outperforms the traditional measures in fitting the New Keynesian Phillips curve. This result provides useful insights for inflation dynamics and monetary policy analysis in China.     

Modelling structural change in the UK housing market: A comparison of alternative house price models

This paper develops a new approach to the modelling of house prices in the UK, with housing demand being conditioned directly on consumers' expenditure rather than the determinants of expenditure. Conditioning on consumption ensures that the permanent income measure used in determining the level of consumption is consistently reflected in housing demand. The effects of financial liberalisation on the relative consumption of housing and non-housing goods and services are captured using the average loan-value ratio for first-time buyers. We also allow for financial effects via the real user cost of home ownership. House prices are assumed to adjust so as to clear the housing market. The proposed model is found to have structurally stable parameters across the housing market downturn since 1990. Statistical comparisons with the more conventional models in use at HM Treasury and the Bank of England during the early 1990s provide additional evidence in favour of our proposed approach.     

The money-age distribution: Empirical facts and the limits of three monetary models

The money-age distribution is hump-shaped for the US post-war economy. There is no clear-cut relation between the variation of money holdings within generations and age. Furthermore, money is found to be only weakly correlated with both income and wealth. We analyze three motives for money demand in an overlapping generations setup in order to explain these observations: (1) money-in-the-utility, (2) an economy with costly credit service, and (3) limited-participation. All three models are consistent with the hump-shaped relation between average money holdings and age, yet they predict a much closer association between money holdings, income, wealth, and age than we find in the data. Only the limited-participation model partly replicates the low bivariate correlation between money and income as well as between money and interest-bearing assets. None of the three models satisfactorily explains these stylized facts.     

Formal targets, central bank independence and inflation dynamics in the UK: A Markov-Switching approach

We examine inflation and uncertainty in the UK with a version of the Markov Switching model, which allows for changes in the variance as well as in the mean and persistence of a series. We find that the UK’s attempts at exchange rate pegs in the form of shadowing the deutschmark and entering the ERM were ineffective, and in the latter case counterproductive in lowering inflation uncertainty. The 1981 budget, however, greatly lowered uncertainty, and the adoption of a formal inflation target also had a palpable, negative impact on inflation uncertainty. As a suggestive exercise, we examine inflation uncertainty in the US, and find that, over 2005–2008, in the absence of an inflation target, uncertainty rose in the US, while uncertainty remained low in the UK over this period of rising commodity prices and financial turmoil.     

Growth, welfare and optimal trade taxes: a fallacy of composition

Optimal export taxation rules out the possibility of immiserizing growth in a two-country world. Thus, productivity increases in the exporting sector must be welfare improving. This paper shows that in a multicountry world such reasoning commits a fallacy of composition. Simultaneous growth of exporting nations can lead to welfare losses in the presence of unilaterally optimal export taxes. Also, optimal export taxes can decline in response to such growth. This result further strengthens the possibility of perverse welfare movements. Thus, standard policy recommendations of increasing productivity in the exporting sector may lead to unintended and self-defeating outcomes.     

Barriers to entry, deregulation and workplace training: A theoretical model with evidence from Europe

We study the impact of regulatory barriers to entry on workplace training. We develop a model of training in imperfectly competitive product and labour markets. The model indicates that there are two contrasting effects of deregulation on training. As stressed in the literature, with a given number of firms, deregulation reduces the size of rents per unit of output that firms can reap by training their employees. Yet, the number of firms increases following deregulation, thereby raising output and profit gains from training and improving investment incentives. The latter effect prevails. In line with the predictions of the theoretical model, we find that the substantial deregulation in the 1990s of heavily regulated European industries (energy, transport and communication) increased training incidence.     

Modeling unemployment as an inventory: A multicointegration approach

We examine the dynamic phenomenon of unemployment as a constantly changing inventory of unemployed individuals. We focus on the possibility raised by Elsby et al. (2009) of an innate “inseparability” between the flows into and out of unemployment. Multicointegration, introduced by Granger and Lee (1989), offers a natural way to model the level of unemployment as an inventory. We find that there is multicointegration between inflows into and outflows from unemployment and the level of unemployment itself. By identifying this multicointegrating relationship, we are able to specify an error correction model for unemployment, improving forecasting ability.     

Calibrating spatial models of trade

Empirical spatial models of trade that are based on a mathematical programming specification often exhibit a large discrepancy between the equilibrium solution and the observed demand, supply and levels of trade flows among countries. This discrepancy may be due to several causes. Assuming, however, that a trade model is not misspecified – in the sense that behavior of the economic agents involved in the specific commodity markets has been included in the study and that the relevant policy instruments have been properly taken into account – the cause of discrepancy may be traced either to imprecision of unit transaction costs or to imprecision in the measurement of the demand and supply functions' parameters, or both. Policy assessments based on this type of imprecise models are distorted. This paper presents a methodology for calibrating mathematical programming spatial trade models of increasing complexity, from the one-commodity case to a multi-commodity model with asymmetric slope matrices of demand and supply functions. The proposed calibration procedure identifies corrections of imperfectly measured parameters. The calibrated models generate solutions that exactly reproduce quantities produced and consumed in all countries, as well as trade flows among all pairs of countries, observed in a given base year. Such models may then serve as a springboard for assessing the impact of various policy changes on economic agents in the countries under study.     

Outside versus inside bonds: A Modigliani–Miller type result for liquidity constrained economies

When agents are liquidity constrained, two options exist – sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government (outside) bonds and in the other they can borrow by issuing (inside) bonds. All transactions are voluntary, implying no taxation or forced redemption of private debt. We show that any allocation in the economy with inside bonds can be replicated in the economy with outside bonds but that the converse is not true. However, the optimal policy in each economy makes the allocations equivalent.     

German unification: What have we learned from multi-country models?

This study reviews early simulations of the effects of German unification using three different rational expectations multi-country models. Despite significant differences in their structures and in the implementations of the unification shock, the models delivered a number of common results that proved reasonably accurate guides to the direction and magnitude of the effects of unification on key macroeconomic variables. Unification was expected to give rise to an increase in German aggregate demand that would put upward pressure on output, inflation, and the exchange rate, and downward pressure on the current account balance. The model simulations also highlighted contractionary effects of high German interest rates on EMS countries.     

Spurious regressions driven by excessive volatility

This paper shows that the excessive volatility results in spurious regressions. The spuriousness can be driven by persistency in the error variances unlike the conventional spurious regressions that are generated by the persistency in the level of regression errors.     

Growth, income taxes and consumption aspirations

In a Barro-type economy with exogenous consumption aspirations, raising income taxes favors growth even in the presence of lump-sum taxes. Such a policy is compatible with the behavior of private consumption, income taxes and growth rates observed in actual economies.     

Cross-border rent shifting in international telecommunications

While scholars have questioned the merits of strategic trade policy, such policies have played a major role in international telecommunications. Countries have traditionally linked bilaterally their termination prices for international telephone calls. I show that this linkage can be rationalized as a mutually beneficial constraint on rent seeking. Linkage becomes more challenging to maintain with telecommunications liberalization, competition, and the growth of alternatives for terminating traffic. I consider possible policy approaches to such developments. Overall, this case study suggests that constraining cross-border rent shifting will present a major transitional challenge in international efforts to liberalize services.     

Biogeographical conditions, the transition to agriculture and long-run growth

We use new data on the timing of the transition to agriculture, developed by Putterman and Trainor (2006), to test the theory of Diamond (1997) and Olsson and Hibbs (2005) that an earlier transition is reflected in higher incomes today. Our results confirm the theory, even after controlling for institutional quality and other geographical factors. The date of transition is correlated with prehistoric biogeography (the availability of wild grasses and large domesticable animal species). The factors conducive to high per capita incomes today are good institutions, an early transition to agriculture, access to the sea and a low incidence of fatal malaria. Geographical influences have been at work in all of these proximate determinants of per capita income.
