This paper explores changes in organizational structure and distinguishes between units' origins. Unit reconfiguration is the addition of units to, deletion of units from, and recombination of units within the firm. This study compares the reconfiguration of internally developed vs. acquired units, explores what forms of unit recombination are common, and observes whether firms pursue recombination before divestiture. Theoretical support is drawn from the dynamic capabilities perspective, research on modular organizational systems, and strategy–structure literature. The findings are that acquired and internally developed units serve different roles in the process of change, and that firms perceive reconfiguration to be beneficial.

Asymmetric responses of money demand to oil price shocks in Saudi Arabia: a non-linear ARDL approach
Mouyad Alsamara Zouhair Mrabet Michel Dombrecht Karim Barkat 《Applied economics》2017,49(37):3758-3769
Saudi Arabia is an open oil-based economy with fixed exchange rates; therefore, it has limited monetary policy autonomy. Using non-linear autoregressive distributed lag approach, this article investigates the asymmetric effects of oil price shocks on the demand of money in Saudi Arabia over the period 1990:Q1–2014:Q4. The empirical results show evidence of positive long run but asymmetric effects of oil price shocks on the money demand. In particular, we find that the positive oil price shocks are more important than negative shocks. Therefore, two policy responses can be considered: either sustaining the fixed exchange rate regime and following an economic diversification policy or switching towards a flexible exchange rate regime to achieve price stability. In that case, the existence of a stable money demand function in Saudi Arabia is a necessary precondition for adopting a monetary policy strategy targeted to price stability using instruments like money targeting. 相似文献

We introduce firm heterogeneity into the standard monopolistically competitive real business cycle (RBC) model. The fundamental equilibrium path is derived and the time–series properties of aggregate GDP are studied analytically. Although firms' productivities are subject to temporary shocks, the aggregate process displays a surprising novel form of nonlinearity and long memory which had not been built into the model at the outset. This aggregate GDP turns out to have very different properties from log–linear time–series models such as auto–regressive (AR) models and their extensions. It displays very strong persistence, which ends abruptly with a sudden change of tendency, giving its autocorrelation function (ACF) an S –shape. Although persistent, it is mean–reverting, unlike the everlasting memory of unit–root processes. Its volatility is of a greater order of magnitude than that of any of its components, so small micro–shocks can generate large macro fluctuations. It is also characterized by long, asymmetric cycles of random lengths. Increased monopoly power tends to reduce the amplitude and increase the persistence of business cycles. Strikingly, we find that the empirical ACFs constructed from GDP data for the U.K. and the U.S. display this characteristic S –shape. 相似文献

This paper empirically studies a model for pricing risky corporate bonds proposed by Baaquie—based on the seminal Merton. The proposed model provides an exact solution for the price of a risky corporate bond with a finite maturity and explains the market price of corporate fixed coupon bonds as being the result of the market risk that is carried by the bond. Baaquie's model is empirically tested using 42 fixed coupon bonds issued by 23 US corporations, between 2011 and 2017. It is found that the proposed model estimates most bond prices quite accurately. Market time (similar to the concept of psychological time), which is distinct from calendar time, is quantified in the paper and is an exogenous behavioral parameter that plays a pivotal role in improving the accuracy of the pricing model for long-maturity risky bonds. 相似文献
