Due to the fast emergence of new wireless technologies, traditional hardware accelerator based wireless baseband processors can no longer meet the requirement of a short time to market. On the other hand, general-purpose processors support good general programming models, which can greatly reduce the development cycle and effort for new mobile devices to support the most advanced wireless techn...

We comprehensively examine the effects of stock return volatility on firms’ financial and investment decisions. Consistent with theories of investment with financing frictions, firms with high volatility actively reduce their leverage, cut investment, increase cash holding, cut non-cash current assets such as inventories and account receivables, and cut dividend. The effects of volatility are s...

Investment-based asset pricing research highlights the role of irreversibility as a determinant of firms’ risk and expected return. In a neoclassical model of a firm with costly scale adjustment options, we show that the effect of scale flexibility (i.e., contraction and expansion options) is to determine the relation between risk and operating leverage: risk increases with operating leverage f...

Working capital behavior has attracted the attention of researchers in relation to company development and financial environment. This study aims investigate determinants speed target adjustment working requirements examine whether constraints lead differences behavior. The sample consists public companies Indonesia for 2011-2018 period. results show that sales growth, leverage, size, operating...

We examine the joint optimization of financial leverage and irreversible capacity investment in a real options framework with risky debt and endogenous interest costs. Higher capacity, ceteris paribus, increases operating leverage and default probability, but lowers ex post adjustment costs and generates larger tax shields. A key insight is that financial leverage and capacity are substitutes i...

This paper discusses summary measures for the speed of adjustment in possibly cointegrated Vector Autoregressive Processes (VAR). In particular we propose long-run half-lives, based on interim and total multipliers. We discuss their relation with Granger-noncausality and other types of half-life, which are shown to convey different information, except in the univariate AR(1) case. We present li...

An optimising model of price adjustment with missing information is developed where firms choose the speed of price adjustment to minimise the expected loss in disequilibrium. The loss is due to lost profits and the expected cost of failing to coordinate price changes with competitors. Assuming that a higher speed of price adjustment decreases the former and increases the latter, it is shown th...

We present a method of speed adjustment as a means of controlling motion in of key-frame animation. This method is designed for key-point trajectories that are expressed as differentiable parametric curves. The animator is given a means of influencing the speed of a trajectory 's traversal by the direct manipulation of a speed-profile curve. Any adjustment of this curve is translated into an ad...

We derive a measure of firm speed of price adjustment that is directly inversely related to market power and compare this to the measure derived by Martin (1993). However, both measures are incorrect when firms have non-zero price conjectural variations and treat competing price levels as exogenous. This is because Taylor series expansions of the demand function implicitly assume that firms inf...

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad ...
