Merger policy,entry, and entrepreneurship

We assess the impact of merger policy on entry and entrepreneurship. When faced with uncertainty about its prospects, and foreseeing that it may wish to leave the market should profitability prove poor, a rational entrant considers possible exit routes. Horizontal merger reduces competition post-merger which, all else being equal, lowers welfare; but merger also provides a valuable exit route. By facilitating exit and thus raising the value of entry, more lenient merger policy may stimulate entry sufficiently that welfare is increased overall. We calculate the optimal merger policy in the form of a low, but positive, profitability threshold below which merger is permitted despite the adverse impact on post-merger competition. This may be viewed as an extension of the “failing firm defence” to include ailing, low profitability firms as well as imminently failing ones. Merger policy is compared with an entry subsidy, and the implications of strategic firm behaviour for the choice of merger policy are also examined.     

The cost of capital,asset prices,and the effects of monetary policy

The primary objective of this paper is to study the interaction between monetary policy, asset prices, and the cost of capital. In particular, we explore this issue in a setting where individuals face idiosyncratic risk. Incomplete information also provides a transactions role for money so that monetary policy can be studied. In contrast to standard monetary growth models which focus on the transmission of monetary policy to the demand for capital goods, we incorporate a separate capital goods sector so that the supply response to monetary policy is taken into account. Consequently, in contrast to the standard monetary growth model, monetary policy plays an important role in investment activity through the relative price of capital goods. Moreover, different sources of productivity can affect the degree of risk sharing. Although the optimal money growth rate falls in response to an increase in productivity in either sector of the economy, monetary policy should react more aggressively to the level of productivity in the capital sector.     

Macroeconomic stabilization,monetary-fiscal interactions,and Europe's monetary union

The euro area recently experienced a prolonged period of weak economic activity and very low inflation. This paper reviews models of business cycle stabilization with an eye to formulating lessons for policy in the euro area. According to standard models, after a large recessionary shock accommodative monetary and fiscal policy together may be necessary to stabilize economic activity and inflation. The paper describes practical ways for the euro area to be able to implement an effective monetary-fiscal policy mix.     

Environmental regulation,political incentives,and mortality in China

China enacted an environmental regulation policy in 1998, the “Two Control Zones” (TCZ) policy, to control air pollution in selected cities. Using a panel dataset of 208 prefectural cities for 2001–2012, this study applies a difference-in-differences approach to examine the policy's impact on mortality and identify the role of political incentives. We find the following aspects. (1) The policy significantly reduces mortality in TCZ cities relative to that in non-TCZ cities by 0.305‰ in the period when the policy is strictly enforced. On average, it translates into a 5.2% reduction in mortality. (2) The effect is particularly salient in the years when local officers are evaluated for political promotion and/or when they face stronger pressure for promotion, thus suggesting that political incentives play an important role in determining the effectiveness of environmental regulation policy. (3) The policy reduces industrial emissions of sulfur dioxide instantaneously, while the accumulation of which eventually leads to a lagged reduction in mortality in the cities. (4) The policy yields health benefits worth 1.1 trillion yuan for the treatment period in our sample (i.e., 2006–2012), which accounts for approximately 5.1% of GDP in 2006.     

Unconventional monetary policy,liquidity trap,and asset prices

This article offers a fundamental critique of monetary policy implemented in the United States following the 2007–8 global financial crisis. It aims to show that the misunderstanding of the mainstream theoretical thinking underlying monetary policy actions led to the ineffectiveness of the policy response to the 2007–8 global financial crisis. The conventional view that monetary policy is the stabilization tool has serious flaws and is ineffective for bringing about economic recovery. The Federal Reserve’s experiment with the so-called unconventional monetary policy exposed the weakness of the conventional belief in understanding how banks operate, how the monetary authority can influence the yield curve, and how the monetary transmission mechanism works, resulting in prescribing an ineffective treatment to boost economic activity. In this regard, it is argued that the Federal Reserve’s decision to let long-term interest rates be market determined represents a significant self-imposed constraint, which limits policy options regarding monetary policy actions and the effective control of long-term interest rates. By limiting the setting of policy rates only to the overnight interest rate, the ability of the monetary authority to influence long-term interest rates is both weak and indirect.     

Labour markets, liquidity, and monetary policy regimes

Abstract.  We develop an equilibrium model of the monetary policy transmission mechanism that highlights information frictions in the market for money and search frictions in the labour market. The information friction increases the persistence in the response of interest rates following monetary policy regime shifts. This occurs because agents have incomplete information about the nature of the shifts and optimally update their inflation forecasts using an 'adaptive' expectations rule. The search friction transmits the interest rate movements to the labour market by affecting job creation activities; together, the two frictions imply that unemployment reacts very gradually to monetary policy shocks.

Monetary and Fiscal Management, Finance, and Growth

This paper addresses three related aspects of monetary and fiscal management in Europe and elsewhere. First, I discuss the implications of economic integration for monetary and fiscal policy, especially the narrow focus on low inflation as the main objective of monetary policy. I argue that because inflation springs from several sources, monetary authorities held responsible by law for maintaining low inflation need to exercise their newfound independence by reserving the right to address all sources of inflation. In this context, I also ponder the question as to whether the increased independence of fiscal policy from short-term political interference would be desirable. Second, I present new empirical evidence of the relationship between inflation, finance, and economic growth across countries, arguing that long-run growth considerations provide an important additional justification for why price stability ought to remain a priority of independent policy makers. Third, I review some further aspects of the relationship between fiscal policy and economic growth, emphasizing the traditional three-pronged role of fiscal management: stabilization, allocation, and distribution, all of which can be conducive to growth. The argument leads to the conclusion that only the stabilization function of fiscal policy and, perhaps, some aspects of the allocation function as well could be usefully delegated in an attempt to immunize them from shortsighted and socially counter-productive political interference, but not the distribution function.     

Factor Endowments,Democracy, and Trade Policy Divergence

We develop a stochastic model of electoral competition in order to study the economic and political determinants of trade policy. We model a small open economy with two tradable goods, each of which is produced using a sector‐specific factor (e.g., land and capital) and another factor that is mobile between these tradable sectors (labor); one nontradable good, which is also produced using a specific factor (skilled labor), and an elected government with the mandate to tax trade flows. The tax revenue is used to provide local public goods that increase the economic agents’ utility. We use this general equilibrium model to explicitly derive the ideal policies of the different socioeconomic groups in society (landlords, industrialists, labor, and skilled workers). We then use those ideal policies to model the individual probabilistic voting behavior of the members of each of these socioeconomic groups. We use this model to shed light on how differences in the comparative advantages of countries explain trade policy divergence between countries as well as trade policy instability within countries. We regard trade policy instability to mean that, in equilibrium, political parties diverge in terms of the political platforms they adopt. We show that in natural resource (land)–abundant economies with very little capital, or in economies that specializes in the production of manufactures, parties tend to converge to the same policy platform, and trade policy is likely to be stable and relatively close to free trade. In contrast, in a natural resource–abundant economy with an important domestic industry that competes with the imports, parties tend to diverge, and trade policy is likely to be more protectionist and unstable.     

Policy Uncertainty,Persistence and Growth*

This paper explores links between policy uncertainty and growth. Using an endogenous growth model in which domestic investment is characterized by irreversibilities and policy fluctuates between a high- and a low-tax regime, it shows that the magnitude of policy fluctuation and the persistence of policy jointly determine the pattern of investment and growth. Cross-section regressions confirm that for 46 developing countries over the 1970-85 period, policy uncertainty is negatively correlated with both investment and growth. Policy persistence also plays an important role.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

Labor market search, sticky prices, and interest rate policies

What accounts for the significant real effects of monetary policy shocks? And what accounts for the persistent and hump shaped responses of output and inflation in response to such shocks? These questions are investigated in a model that incorporates labor market search, habit persistence, sticky prices, and policy inertia. While habit persistence and price stickiness are important for the hump shaped output response and the long, drawn out inflation response, respectively, labor market frictions increase the output response and reduce the inflation response relative to an otherwise similar model based on a Walrasian labor market. Significantly, policy inertia itself is found to be the most important factor in accounting for the magnitude of the output effects of policy shocks in the model.     

Adverse selection,asymmetric information,and foreign investment policies

This paper explores the welfare consequences of foreign investment taxation in a small open economy, based on the notion that the true productivity of imported capital may be unknown to policy-makers. It is shown that while asymmetric information between capital importers and the host government precludes the use of a productivity specific policy measure, an across-the-board policy suffers from the problem of adverse selection among capital imports of differential productivities. Conditions under which a reversal of the optimal foreign investment policy in the face of asymmetric information are examined.     

Access Pricing,Quality Degradation,and Foreclosure in the Internet

Access to both a local and a global network is needed in order to get complete connection to the Internet. The purpose of this article is to examine the interplay between those two networks and how it affects the domestic public policy towards a domestic provider of local access. We find that a cost-oriented regulation is detrimental to domestic welfare, because it shifts profit to the foreign provider of global access. The optimal policy is that the regulator commits itself to set an access price above costs, possibly the same price as in an unregulated market economy. A regulation of the global access price has a non-monotonic effect on domestic welfare, and there is a potential conflict between international and domestic regulation policy.     

Oligarchy, democracy, and state capacity

We develop a dynamic political economy model in which investment in the state capacity to levy taxes and deter crime is a policy variable, and we study the evolution of state capacity when policy is chosen by an elite. We show that democratization in the sense of expansion of the elite leads to an increased investment in state capacity and to a reduction in illegal activities and has nonmonotonic effects on tax rates as it reduces the willingness of the elite to engage in particularistic spending but enhances its willingness to provide public goods. Depending on initial conditions, consensual political changes may lead either to democratization or to the entrenchment of an immovable elite.     

Behavioural Economics,Hyperbolic Discounting and Environmental Policy

This paper reviews some recent research in “behavioural economics” with an application to environmental issues. Empirical results from behavioural economics provide a reminder that human behaviour is context-dependent, implying that policy may go awry if based upon models of behaviour which are inappropriate to the contexts in which decisions are made. Recognizing that agents may, in some contexts, systematically make mistakes raises challenging questions about the role of “paternalism” in government policy. The paper considers the research into hyperbolic discounting, and examines the implications for environmental policy. We develop a model of resource management under hyperbolic discounting, which shows that if a planner is unable to commit to a policy, the temptation to re-evaluate the policy in future could lead to an inadvertent collapse in the stocks of a natural resource.     

A Behavioral Model of Unemployment,Sociotropic Concerns,and the Political Economy of Trade Policy

We present a behavioral model in which agents are concerned about the scarring effects from unemployment for themselves and others and explore the manner in which unemployment matters for trade policy. We derive three policy implications: the government has an incentive to increase employment in sectors characterized by “good jobs,” where the good job/bad job characterization depends on an industry's job creation and destruction rates; the government has an incentive to pursue this policy in a gradual fashion by channeling new and unemployed workers into the appropriate sector; and opposition to trade liberalization can be reduced by welfare state policies.     

地域比较、政策构建与创业激励

地域特点、政策构建和创业激励具有内在关联。与中关村、东湖、张江自主创新示范区创业激励政策相比较,长株潭示范区创业政策制定缺乏主体性,政策内容和政策执行还存在不足。优化长株潭自主创新示范区的创业激励政策,须通过完善机构职能、实现多元主体协调,突出战略性和创业激励政策的整体性,并从创业教育、创业贷款和创业投资政策方面完善创业激励政策的具体内容;通过舆论宣传、组织保障和动态评估提高创业政策执行力度。     

Aging, Public Budgets, and the Need for Policy Reform

Projections show that, without policy changes, population aging will lead to unsustainable developments in public budgets. Various policy options to address this challenge are reviewed. Particular emphasis is given to the incentives to retire early and the programs that generate these incentives. The requirements for labor markets to absorb an added supply of older workers are discussed.     

Monetary policy, oil shocks, and TFP: Accounting for the decline in US volatility

An equilibrium model is used to assess the quantitative importance of monetary policy for the post-1984 decline in US inflation and output volatility. The principal finding is that monetary policy played a substantial role in reducing inflation volatility, but a small role in reducing real output volatility. The model attributes much of the decline in real output volatility to smaller TFP shocks. We also investigate the pattern of output and inflation volatility under an optimal monetary policy counterfactual. We find that real output volatility would have been somewhat lower, and inflation volatility substantially lower, had monetary policy been set optimally.     

Fiscal policy,growth, income distribution and sociopolitical instability

This paper identifies the fiscal instruments that governments can use to promote economic growth when sociopolitical instability (SPI) is present. We show that fiscal policy that takes into account income distribution and SPI transforms a neoclassical growth model into one with both endogenous growth and a poverty trap. Under these circumstances, the growth rate of the economy depends upon SPI, fiscal policy and income distribution. The baseline level of SPI determines an economy's ability to grow. If SPI is high, the economy remains in a poverty trap even if fiscal policy instruments are set appropriately.
