The paper examines the processes underlying economic fluctuations by investigating the volatility moderation of U.S. economy
in the early 1980s. We decompose the volatility decline using a dynamic factor framework into a common stochastic trend, common
transitory component and idiosyncratic components. We find that the moderation of business cycle was a result of the moderation
in transitory and idiosyncratic components. Our results suggest that important part of stochastic process that drives economy
is transitory. The paper investigates the role of oil prices, monetary and financial market factors. Proposed economic factors
do not have a significant relationship to either transitory or permanent components. In addition, we find that transitory
shocks are as common during the 1980s and 1990s as they were during the 1960s and 1970s.

The digitalization of the newspaper industry represents a significant challenge for incumbent companies to engage new technologies. Many companies in the industry have had to seek new markets through digital technologies to survive. This paper explores how one of the largest Swedish newspapers, Aftonbladet, has strategically embraced new media and new markets. We report a decade of engaged scholarship based on interviews and archival analysis that covers 20 years of strategic acts at the company. We consider this effort as a case of organizational ambidexterity under digitalization. The analysis seeks to extend theoretical understanding of the interrelationships between strategic intent and technological choice. The paper contributes to the understanding of ambidexterity under digitalization by theoretically framing it in terms of strategic acts. The research suggests that digitalization implies a more complex ambidexterity interrelationship between old and new markets and technologies. As digitalization enables the loosening of previously tight couplings, the clear theoretical distinction between old and new, and critically, the unproblematic transition, is brought into question. The paper suggests replacing the notion of an orderly shift from the old to the new with ambidexterity under digitalization as a duality of both old and new undergoing continual reconfiguration. 相似文献

This paper examines how the sentiment of firm-specific news affects CDS spreads conditional on the degree of information asymmetry. Using a large set of news releases, we document a strong negative relationship between the sentiment of firm-specific news and CDS spreads. More importantly, consistent with the role of public news in reducing information asymmetry, we find evidence that the relation between news sentiment and CDS spreads is stronger for firms with higher information asymmetry. Furthermore, the relation is stronger for news with negative sentiment and during the 2008 financial crisis. Our results are robust to alternative sentiment measures. 相似文献

Using the workweek of capital as a measure of capital utilization, we empirically test whether news shocks actually increase capital utilization. To this end, by estimating a panel VAR on two-digit manufacturing data identifying news shocks as innovations to stock returns orthogonal to the variations in current-period TFP growth, we find the positive response of capital utilization to news shocks. Moreover, to explain the positive response of capital utilization to news shocks in terms of plant-level investment behavior, we propose a heterogeneous plant model that combines the fixed cost of capital adjustment and an endogenous capital utilization choice. With the presence of fixed costs, except for the plants that have recently adjusted capital stock, news shock shortens the effective time horizon of currently installed capital stock and increases capital utilization. When the model economy is calibrated to match the salient features of the plant-level investment rate distribution, the economy generates a news-driven positive response of capital utilization. 相似文献

In this paper, we empirically investigate the effects of monetary policy shocks on exchange rates in Asian countries. To do so, we use VAR models which impose sign restrictions on impulse responses to identify monetary policy shocks. We find that contractionary monetary policy shocks lead to significant exchange rate appreciation in Malaysia, the People’s Republic of China, and the Republic of Korea. However, in India, Indonesia, the Philippines and Thailand, we find either a significant depreciation or no significant effect. These results suggest that an interest rate increase (or decrease) may not necessarily shield Asian countries from exchange rate depreciation (or appreciation) pressure following a U.S. interest rate increase (or decrease). 相似文献

I examine the relationship between aggregate news sentiment, S&P 500 index (SPX) returns, and changes in the implied volatility index (VIX). I find a significant negative contemporaneous relationship between changes in VIX and both news sentiment and stock returns. This relationship is asymmetric whereby changes in VIX are larger following negative news and/or stock market declines. Vector autoregression (VAR) analysis of the dynamics and cross-dependencies between variables reveals a strong positive relationship between previous and current period changes in implied volatility and stock returns, while current period and lagged news sentiment has a significant positive (negative) relationship with stock returns (changes in VIX). I develop a simple trading strategy whereby high (low) levels of implied volatility signal attractive opportunities to take short (long) positions in the underlying index, while extremely negative (positive) news sentiment signals opportunities to enter short (long) index positions. The investor fear gauge (VIX) appears to perform better than news sentiment measures in forecasting future returns. 相似文献

This article studies the triggers and the agglomeration of mergers and acquisitions (M&A) activity within clusters constituted by time, market and industry. Based on almost 500,000 individual transactions, we find that industry factors play a significant role in triggering activity and that M&A agglomerates strongly across related industries. While clustering in time turns out to be insignificant, stock market effects can be either an attracting or a repelling force, depending on the type of deal examined. This supports the view that merger waves are largely driven by industry shocks. 相似文献

Using BoC-GEM-Fin, a large-scale dynamic stochastic general equilibrium (DSGE) model with real, nominal, and financial frictions featuring a banking sector, we explore the macroeconomic implications of various types of countercyclical bank capital regulations. Results suggest that countercyclical capital requirements have a significant stabilizing effect on key macroeconomic variables, but mostly after financial shocks. Moreover, the bank capital regulatory policy and monetary policy interact, and this interaction is contingent on the type of shocks that drive the economic cycle. Finally, we analyze loss functions based on macroeconomic and financial variables to arrive at an optimal countercyclical regulatory policy in a class of simple implementable Taylor-type rules. Compared to bank capital regulatory policy, monetary policy is able to stabilize the economy more efficiently after real shocks. On the other hand, financial shocks require the regulator to be more aggressive in loosening/tightening capital requirements for banks, even as monetary policy works to counter the deviations of inflation from the target. 相似文献
