Franchise fee,contract bargaining,and economic growth

This paper combines the industrial organization (IO) theory and the R&D-based endogenous growth theory in a model of a successive imperfect competitive economy. The current study assumes that firms between upstream and downstream industries bargain over both the price of intermediate goods and the franchise fee. Findings show that the intermediate goods firm with a R&D sector charges the price equal to the marginal cost. Economic rent may also be partly transferred into the franchise fee determined by the relative bargaining power. In particular, the traditional double marginalization result, such as in Spengler (1950), does not take place here due to the above-mentioned bargaining scheme. Finally, this work shows that final goods firms in vertically linked industries play an important role in an economic growth model. The more bargaining power the final goods firms have (or the more returns to specialization upstream firms have, or the less substitution elasticity the final goods have), the more the economy grows. However, the consumer preference for diversity seemingly does not affect economic growth rate.     

A weak bargaining set for contract choice problems

In this paper, we consider the problem of choosing a set of multi-party contracts, where each coalition of agents has a non-empty finite set of feasible contracts to choose from. We call such problems, contract choice problems. The main result in this paper states that every contract choice problem has a non-empty weak bargaining set. The need for such a solution concept which is considerably weaker than the core arises, since it is well-known that even for very simple contract choice problems, the core may be empty. We also show by means of an example that an analog of the bargaining set due to Mas-Colell [Mas-Colell, A., 1989. An equivalence theorem for a bargaining set. Journal of Mathematical Economics 18, 129–139], as well as the natural analog of the bargaining set due to Aumann and Mashler [Aumann, R., Maschler, M., 1964. The bargaining set for cooperative games. In: Dresher, M., Shapley, L., Tucker, A. (Eds.), Advances in Game Theory. Princeton University Press, Princeton, NJ] may be empty for contract choice problems.     

Nursing home choice,family bargaining,and optimal policy in a Hotelling economy

We develop a model of family bargaining to study the impact of the distribution of bargaining power within the family on the choice of nursing homes by families, and on the locations and prices chosen by nursing homes in a Hotelling economy. In the baseline (static) model, where the dependent parent cares only about the location of the nursing home, the markup of nursing homes is increasing in the bargaining power of the dependent parent, and nursing homes are located at the extreme periphery. We compare the laissez‐faire with the social optimum (which involves more central locations of nursing homes), and examine its decentralization in first‐best and second‐best settings. We explore the robustness of our results to introducing a bequest motive in a dynamic overlapping generations model, which allows us to study the joint dynamics of wealth accumulation and nursing home prices. If the bequest motive is strong, the markup is decreasing in the bargaining power of the dependent. However, wealth accumulation, by reducing interest rates, raises markup rates and nursing homes prices.     

Endogenous contract structure and monetary policy

We analyze the co-determination of monetary policy and the labor contracts chosen by members of the public, who can either fix or index their nominal wages. Fixed nominal wages allow the central bank to offset productivity shocks, while the public fix nominal wages in response to the central bank offsetting shocks; so there is an equilibrium in which, realistically, nominal wages are fixed and shocks offset: a result which holds in single- as well as in multi-period games. In addition, there may be equilibria in which agents index their nominal wages, and the central bank optimally responds by stabilizing price. In contrast to conventional models, the Ramsey rule may be implemented in a finitely repeated game. The central bank does not deviate for fear that agents would change their labor contracts such that the central bank's least favored equilibrium will subsequently be played.     

Nominal bargaining power, selection protocol, and discounting in legislative bargaining

The comparative static predictions of the Baron and Ferejohn [Baron, D.P., and Ferejohn, J.A., (1989). Bargaining in legislatures, American Political Science Review 83 (4), 1181-1206] model better organize behavior in legislative bargaining experiments than Gamson's Law. Regressions similar to those employed in field data produce results seemingly in support of Gamson's Law (even when using data generated by simulating agents who behave according to the Baron-Ferejohn model), but this is determined by the selection protocol which recognizes voting blocks in proportion to the number of votes controlled. Proposer power is not nearly as strong as predicted in the closed rule Baron and Ferejohn model, as coalition partners refuse to take the small shares given by the continuation value of the game. Discounting pushes behavior in the direction predicted by Baron and Ferejohn but has a much smaller effect than predicted.     

Comparative statics of the optimal dynamic incentive contract

Each period a firm must carry out an indivisible project, the cost of which depends on the firm's constant efficiency and its (variable) level of ‘effort’. Only the cost is observed by the regulator who has to choose the incentive scheme. The optimal dynamic mechanism is derived under possible commitment of the regulator over time. Then, under non-commitment, it is shown that there are four types of continuation equilibria. Also the profile of effort levels is compared to the commitment case. Finally, some numerical comparative statics is performed and it is shown that all types of equilibria can be optimal.     

The optimal insurance contract in a competitive market

The author reviews some earlier work on optimal insurance contracts by Arrow and Mossin. He then shows that some results in this work carry over to any premium system which satisfies the additivity condition inherent in a competitive market.     

Incomplete markets,liquidation risk,and the term structure of interest rates

We analyse the term structure of interest rates in a general equilibrium model with incomplete markets, borrowing constraint, and positive net supply of government bonds. Uninsured idiosyncratic shocks generate bond trades, while aggregate shocks cause fluctuations in the trading price of bonds. Long bonds command a “liquidation risk premium” over short bonds, because they may have to be liquidated before maturity – following a bad idiosyncratic shock – precisely when their resale value is low – due to the simultaneous occurrence of a bad aggregate shock. Our framework endogenously generates limited cross-sectional wealth heterogeneity among the agents (despite the presence of uninsured idiosyncratic shocks), which allows us to characterise analytically the shape of the entire yield curve, including the yields on bonds of arbitrarily long maturities. Agents? desire to hedge the idiosyncratic risk together with their fear of having to liquidate long bonds at unfavourable terms implies that a greater bond supply raises the level of the yield curve, while an increase in the relative supply of long bonds raises its slope.     

Evolution, bargaining, and time preferences

I include a role for time preferences within a version of the Young (J Econ Theory 59:145–168, 1993b) evolutionary model of bargaining. With or without time preferences, the stochastic stable convention yields a generalized version of the Nash (Econometrica 18:155–162, 1950) Bargaining Solution. When time preferences are added to the model, agents’ discount factors enter into the stochastically stable convention in a natural manner. That is, an agent’s discount factor acts as a bargaining weight within the Nash Bargaining Solution. By taking appropriate limits, an evolutionary foundation for the Rubinstein (Econometrica 50:97–110, 1982) Bargaining Solution is provided.

Search cost,trading strategies and optimal market structure

The theory of Walrasian equilibrium yields a set of prices at which the aggregate competitive demand for each commodity equals its aggregate competitive supply. However, even at equilibrium prices the theory of competitive equilibrium does not explicitly offer explanation regarding the manner in which trades are actually executed. This paper considers a model where trade takes place in a decentralized fashion and examines in a dynamic game-theoretic framework, the role of social institution of money and markets in facilitating exchange. The steady state Nash equilibrium derived in the paper demonstrates how, depending on the level of transaction costs associated with a market setup (synonymously, trading posts to exchange possible pairs of goods) appropriate monetary trade emerges, which like a hub and spoke network (Starr and Stinchcombe, 1999) makes some markets non-functioning and in equilibrium only the markets having trade through the medium of exchange continue to exist. However, despite the obvious advantages of a market setup in reducing search costs, pure random search for a complementary trading partner (as considered by Ostroy and Starr, 1974; Kiyotaki and Wright , 1989; and others) prevails in many economies, especially, in many developing economies. This paper models this feature of developing economies by introducing differences in transaction costs across agents and shows why sustainable equilibria might exist exhibiting random search for certain commodities even in the presence of established markets.     

Wage bargaining,trade and growth

We construct a North-South product-cycle model of trade with fully-endogenous growth and union wage bargaining. Economic growth is driven by Northern entrepreneurs who conduct R&D to innovate higher quality products. Northern production technologies can leak to the South upon successful imitation. The North has two sectors: a tradable industrial goods sector (manufacturing) where wages are determined via a bargaining process and a non-tradable sector (services) where wages are flexible. The South has only a tradable industrial goods sector where wages are flexible.We find that unilateral Northern trade liberalization, in the form of lower Northern tariffs on industrial goods, increases the rate of innovation but decreases both the bargained wage in the industrial sector and the flexible wage in the service sector. The wage effects are relative to the Southern wage rate. We also consider a variant of the model with Northern unemployment, driven by a binding minimum wage in the non-tradable service sector. In this case, Northern tariff cuts decrease the innovation rate and the bargained wage rate. In addition, the Northern unemployment rate increases. The model thus highlights the role of labor market institutions in determining the growth and labor market effects of tariff reductions. We also study the effects of unilateral Southern trade liberalization.     

On the optimal social contract: Agency costs of self-government

In a typical study of political economy, citizens are regarded as the principals, and government as the agent. In contrast, classical theorists of democracy such as Jean-Jacques Rousseau and James Madison were deeply interested in the dual nature of people; they are the principals (citizens sharing the sovereign power) and, at the same time, the agents (subjects under the laws). Government, in their framework, is an intermediate body which helps people solve their self-control problem. Equipped with tools of modern economics, this paper explores the classical problem to see how economic development and political institutionalization relate to the structure of government and the quality of public sector. In particular, I consider repeated games with a large population and incomplete information, in which players decide whether to sacrifice private consumption to provide public goods. Because both people and the executive of the public projects are subject to moral hazard, the people spend resources to monitor the executive and the people themselves. The optimal self-enforcing contract, which can be interpreted as an efficiency upper bound of political systems, is characterized. An analysis of the contract shows that as a country gets more economically developed and politically institutionalized, the agency problem on the people’s side becomes negligible and that poor economic performance of a country might prevent the citizens from establishing a more efficient public sector.     

Wage bargaining, labor-tax progression, and welfare

This paper analyzes the effect of labor-tax progression on employment and welfare in an economy with a unionized labor market. The government influences wage bargaining through its tax policies. Wages can be reduced by increasing the marginal labor-tax rate. If there are no restrictions on profit taxation, a first-best optimum with full employment is realized; this first-best optimum can always be implemented by a progressive tax schedule. If profit taxation is restricted, unemployment may arise. For this case, we show that the welfare-maximizing degree of tax progression is influenced by a variety of factors, in particular the wage elasticity of labor demand, the distribution of bargaining power, and the existence of unemployment benefits. Examples are given for both progressive and regressive tax structures. Comparative-static analysis reveals that a decline in union bargaining power, an increase in unemployment benefits, and an increase in the overall work force reduce the efficient degree of tax progression.     

Openness, centralized wage bargaining, and inflation

This paper develops a model of an open economy containing both sectors in which wages are market-determined and sectors with wage-setting arrangements. A portion of the latter group of sectors coordinate their wages, taking into account that their collective actions influence the equilibrium inflation outcome in an environment in which the central bank engages in discretionary monetary policymaking. Key predictions forthcoming from this model are (1) increased centralization of wage setting initially causes inflation to increase at low degrees of wage centralization but then, as wage centralization increases, results in an inflation drop-off; (2) a greater degree of centralized wage setting reduces the inflation-restraining effect of greater central bank independence; and (3) increased openness is more likely to reduce inflation in nations with less centralized wage bargaining. Analysis of data for seventeen nations for the period 1970–1999 provides generally robust empirical support for all three of these predictions.     

Union bargaining power, employment, and output in a model of monopolistic competition with wage bargaining

This paper examines the implications of a rise in the bargaining power of workers on the real wage, income distribution, and the levels of employment and output using a macroeconomic model with monopolistic competition and worker-owner Nash bargaining at the firm level. It thereby provides optimizing microfoundations to Kalecki's macroeconomic analysis of the positive effect on output of a rise in trade-union power, and contrasts it with the neoclassical view based on the diminishing marginal productivity of labor.     

Trade agreements, bargaining and economic growth

Rebelo’s two-sector endogenous growth model is embedded within a two-country international trade framework. The two countries bargain over a trade agreement that specifies: (i) the size of the foreign aid that the richer country gives to the poorer one; (ii) the terms of the international trade that takes place after the aid is given. Foreign aid is given not because of generosity, but because it improves the capital allocation across the world and thus raises total world production. This world production surplus enables the rich country to raise its equilibrium consumption and welfare beyond their no-aid levels. To ensure it, the rich country uses a trade agreement to condition the aid on favorable terms of trade.     

Unemployment, wage bargaining and capital-labour substitution

Many economists believe that capital accumulation, technicalprogress and labour force expansion have no lasting effect onunemployment. This view rests on the empirically doubtful assumptionthat the elasticity of substitution between labour and capitalis equal to unity (i.e., production is Cobb-Douglas). Usinga simple model based on the work of Layard, Nickell and Jackman,this paper demonstrates that, with a lower elasticity of substitution,the equilibrium unemployment rate is affected by all of theabove factors. It considers briefly how capital accumulationmay be endogenised and what long-run implications this has forunemployment.     

Search, Nash bargaining and rule-of-thumb consumers

This paper analyses the effects of introducing two typical Keynesian features, namely rule-of-thumb (RoT) consumers and consumption habits, into a standard labour market search model. RoT consumers use the margin that hours and wage negotiation provides them to improve their lifetime utility, by narrowing the gap in utility with respect to Ricardian consumers. This margin for intertemporal optimisation has not been studied yet, because this class of restricted agents has been mainly used in models with no equilibrium unemployment. Our approach allows for a deeper study of the effects of shocks on vacancies, unemployment, hours, wages and how they interact. As habits increase, RoT consumers find it optimal, after a positive technology shock, to negotiate lower hours and higher wages, and this mechanism reduces the simulated correlation between the real wage (or productivity) and total hours to values closer to those obtained empirically. Thus, with the interaction of RoT consumers and consumption habits, the labour market search model improves significantly in reproducing some of the stylised facts characterising the US labour market.     

Collective bargaining,firm heterogeneity and unemployment

We compare labor market outcomes under firm-level and sector-level bargaining in a one-sector Mortensen-Pissarides economy with firm-specific productivity shocks. Our main theoretical results are two-fold. First, unemployment is lower under firm-level bargaining, due both to a lower job destruction rate and a higher job-finding rate. Key to this result is the interplay between firm heterogeneity and wage compression under sector-level bargaining. Second, introducing efficient opting-out of sector-level agreements suffices to bring unemployment down to its level under decentralized bargaining.     

Investment-based optimal capital structure

This paper extends the classical capital structure model by introducing the output of firm with ‘AK’ production technology dynamically depends on the endogenous investment decision and capital accumulation. Based on our calibration, it shows that the flexibility of dynamic investment and capital accumulation induces the firm to take the lower leverage at financing time and makes the leverage estimate closer to empirically observed leverage ratios, which provides an effective explanation for the ‘under-leverage puzzle’. In addition, this model predicts that the market leverage behaves in a U-shaped manner with capital liquidity, which provides a novel empirical test.
