摘要

最近发生的2019冠状病毒病(COVID-19)产生了一些非常规问题,这些问题具有高度不确定性,难以用完全理性决策模型来解决。在金融领域,这些问题是与财政和货币政策有关的问题,这些问题必须与经济衰退作斗争,或者在金融市场动荡的情况下进行投资。关于财政和货币政策,政府和中央银行可能会尝试使用同样的策略,这些策略在缓解2007 - 2008年大衰退的影响方面取得了成功,尽管最近的衰退有不同的原因。一些发达国家推出了刺激计划,为受疫情影响的经济部门分配了可观的财政资源。然而,与大衰退(Great Recession)的情况一样,情况的复杂性使得很难客观分配这些资源。对欧洲联盟来说,最近危机的战略解决办法的一个特点是,其中许多都是通过集体决定通过的,必须调和参与者的各种利益。在许多国家,国内生产总值的下降、预算赤字的增加和目前的低利率可能迫使人们在高失业率和加速通货膨胀之间作出选择。在此类决策中,通常对失业率演变非常敏感的政府的目标,可能会与专注于价格稳定的央行的目标形成竞争。加速的通货膨胀可能会使许多发达国家的人民感到震惊,这些国家在不久前已经习惯了舒适的货币稳定。它还可能破坏央行的信誉,导致对本国货币的不信任。在这种情况下,通胀预期将不再是货币政策的工具,而是实现货币政策目标的障碍。它们还可能增加某些金融决策的不确定性,改变各类投资者、债权人或债务人的行为。2020年第一季度,有关新冠肺炎疫情传播和救助经济措施的消息,在发达和新兴资本市场引发了不同寻常的大量正面和负面冲击。这种动荡可以看作是在危机时期经常发生的过度反应的症状。对自身健康的担忧改变了一些投资者的行为,这是可能的,尽管不容易证明。波动加剧可能会吓退许多厌恶风险的投资者,但也可能吸引一些过去喜欢冒险的投资者。在一些国家,本国货币贬值,汇率波动加剧。就像以前在其他动荡时期发生的那样,黄金对投资者来说成了一种有吸引力的资产。新冠肺炎疫情引发的财政、货币政策、投资等部分决策的理性界限,在金融领域尚属首次。这对研究财务决策非理性原因的行为金融学来说是一个挑战。然而,在目前很难估计COVID-19大流行会持续多久的情况下,也很难预测这种情况是否会导致行为金融学领域的新方法。

Provocări pentru Finanţele Comportamentale în contextul COVID-19 (Some Challenges for the Behavioral Finance in the Context of COVID-19)
The recent coronavirus disease 2019 (COVID-19) generated some non-routine problems, characterized by a high degree of uncertainty which makes difficult the solving by the full rational decision making models. In the field of finance, such problems are those associated to the fiscal and monetary policies, that have to fight the recession or to investments in the presence of turbulences on the financial markets. Regarding the fiscal and monetary policies, governments and central banks could be tempted to use the same strategies that were successful in mitigating the effects of the Great Recession from 2007 – 2008, although the recent recession has different causes. In some developed countries there were launched stimulus packages, which allocated impressive financial resources to the economic branches affected by COVID-19. However, as in the case of Great Recession, the complexity of the circumstances made very hard an objective assignment of these resources. For the European Union, a particularity of the strategic solutions to the recent crisis is the fact that many of them are adopted by group decisions, where various interests of the participants have to be conciliated. In many countries, the fall of GDP, the rise of budget deficits and the present low interest rates could impose the choice between a high unemployment and an accelerating inflation. In such decisions, the objectives of governments, usually, very sensitive to the unemployment evolution, could compete with those of the central banks preoccupied by the prices stability. An accelerating inflation could shock the populations from many developed countries which, in the recent past, got used to a comfortable monetary stability. It could also undermine the central banks credibility, leading to distrust in the national currencies. In such situations, the inflation expectations would be no longer a tool for the monetary policies, but an obstacle for their objectives. They could also increase the uncertainty for some financial decisions, modifying the behaviors of various categories of investors, creditors of debtors. In the first quarter of 2020, the news about the COVID-19’s propagation and about the measures meant to help the economies provoked an unusual large number of negative and positive shocks on the developed and emerging capital markets. Such turbulences could be viewed as symptoms of overreactions which occur often in the times of crisis. It is possible, although not easy to prove, that the concern for their own health changed the behavior of some investors. The increased volatility could intimidate many risk-averse investors, but it could also attract some investors who use to take high risks. In some countries, the national currencies depreciated and the volatility of the exchange rates increased. As it happened before in other turbulent times, the gold became an attractive asset for investors. The potential boundaries of the rationality induced by COVID-19 in some decisions such as those regarding fiscal and monetary policies or investments are, somehow, new for the field of the finance. They could be viewed as challenges for the Behavioral Finance which studies the causes of irationality in the financial decision making. However, in the present days, when it is very hard to estimate for how long the COVID-19 pandemic will last, it is also very difficult to predict if such situation would lead to new approaches in the field of the Behavioral Finance.
