The economic crisis of the 1990s in Finland 总被引:2,自引:0,他引:2
In the 1990s, Finland underwent a deep depression as its GDP dropped about 14% and unemployment rose from 3 to almost 20%. This is a story of bad luck and bad policies. Bad luck took the form of external shocks: the collapse of trade with the former Soviet Union in 1991, but also sharp cycles in the OECD area. However, bad luck is far from being the whole story. In the absence of bad policies, Finland would have experienced a recession, not a depression. Bad policies included a poorly designed financial regulation and mistaken reactions to the onset of the crisis. Of particular interest is the role of financial factors in triggering the crisis and aggravating the effects of bad policies. Not only were consumption and investment spending hurt by the credit crunch, but there is evidence that the private sector's indebtedness has increased structural unemployment, which explains why the recovery is proceeding with few job creations. A number of general lessons emerge. They concern the deregulation of financial markets, the policy reaction to massive capital inflows and the role of employment policies. 相似文献

A mathematical characterization of self-enforcing bilateral contracts is given. Contracts where both parties exercise some control over the quantity traded can sometimes be superior to contracts that rest control entirely with one side. Some qualitative characteristics of these contracts are given. 相似文献

The purpose of this paper is to analyze the stability of systems of piecewise continuous differential equations, and to apply the results to a disequilibrium economic model. The discontinuity problem appears in disequilibrium models because of the so-called “short-side” rule. The concept of Filippov solution makes it possible to analyze the dynamic evolution of such a model. This paper demonstrates that (i) stability conditions for each subsystem are neither necessary nor sufficient for overall stability, except in special cases such as a system of linear differential equations in R2 with two regimes separated by a linear boundary; (ii) several sufficient conditions for overall stability with many regimes are available; and (iii) stability theorems with regime switching are useful for disequilibrium economic models with several regimes. 相似文献

We study the properties of the generalized stochastic gradient (GSG) learning in forward‐looking models. GSG algorithms are a natural and convenient way to model learning when agents allow for parameter drift or robustness to parameter uncertainty in their beliefs. The conditions for convergence of GSG learning to a rational expectations equilibrium are distinct from but related to the well‐known stability conditions for least squares learning. 相似文献

When managers get to trade in options received as compensation, their trading prices reveal several aspects of subjective option pricing and risk preferences. Two subjective pricing models are fitted to show that executive stock option prices incorporate a subjective discount. It depends positively on implied volatility and negatively on option moneyness. Further, risk preferences are estimated using the semiparametric model of Aït-Sahalia and Lo (2000). The results suggest that relative risk aversion is just above 1 for a certain stock price range. This level of risk aversion is low but reasonable, and it may be explained by the typical manager being wealthy and having low marginal utility. Related to risk aversion, it is found that marginal rate of substitution increases considerably in states with low stock prices. 相似文献

What is the impact of surprise and anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations? We examine this issue using the standard stochastic real business cycle model with lump-sum taxes. Agents combine knowledge about future policy with econometric forecasts of future wages and interest rates. Dynamics under learning can have large impact effects and a gradual hump-shaped response, and tend to be prominently characterized by oscillations not present under rational expectations. These fluctuations reflect periods of excessive optimism or pessimism, followed by subsequent corrections. 相似文献

We examine the nonlinear model xt=EtF(xt+1). Markov stationary sunspot equilibria (SSEs) exist near an indeterminate steady state, , provided . Despite the importance of indeterminacy in macroeconomics, earlier results have not provided conditions for the existence of adaptively stable SSEs near an indeterminate steady state. We show that there exist Markov SSEs near x? that are E-stable, and therefore locally stable under adaptive learning, if . 相似文献

The present paper provides further empirical evidence on the credit view (i.e., bank credit availability has a positive impact on macroeconomic activity) by investigating the case of Finland. The Finnish economy suffered a severe recession in the early 1990s that was marked by widespread banking crisis and extensive government intervention. Using monthly data for the 1980–1996 period, unrestricted and restricted vector autoregression (VAR) models with GDP, money supply, consumer prices, bank credit, and exports were estimated. It is found that, while money supply had the largest effect on economic output, bank credit exhibited a fairly strong effect on output that exceeded price effects for the most part. Exports had little impact on fluctuations in GDP but did help to explain industrial output changes over time. Based on these results, it is concluded that there is empirical support for the credit view in Finland. By implication, government intervention in Finland to restore safety and soundness during the banking crisis likely limited further damage to the macroeconomy associated with disruption of credit intermediation services. 相似文献
