ABSTRACT Tax regimes treat losses and profits asymmetrically when profits are immediately taxed, but losses are not immediately refunded. We find that treating losses less asymmetrically by granting refunds less restrictively increases loss firms' investment: A third of the refund is invested and the rest is held as cash or returned to shareholders. However, the investment response is driven primarily by firms prone to engage in risky overinvestment. Consistent with the risk of misallocation, we find a delayed exit of low-productivity loss firms receiving less restrictive refunds, indicating potential distortion of the competitive selection of firms. This distortion also negatively affects aggregate output and productivity. Our results suggest that stimulating loss firms' investment with refunds unconditional on their future prospects comes at the risk of misallocation. JEL Classifications: G31; H21; H25.

Investment Fluctuation

This paper applies business cycle accounting methodology to analyze the sources of aggregate fluctuations in Thai economy, especially during the recent severe recessions in 1997–1998 and 2008–2009. This exploration helps researchers uncover possible shocks and frictions that drive business cycle in a small and open economy within a minimal model set-up. Under this methodology, a fluctuation in aggregate output can be accounted for by exogenous time-varying wedges, namely efficiency wedge, investment wedge, labor wedge, government wedge, etc. This study found that the efficiency wedge is essential in accounting for aggregate output, consumption and investment fluctuation, while the bond wedge, which only present in an open economy setting, is a prime factor in accounting for movement in current accounts. I conducted counterfactual experiments to see what accounts for the output drop during recent recessions. I find that the efficiency wedge played a key role in recent recessions in Thailand, while the investment wedge was accounted for slow economic recovery after the recessions.

Compensatory Effect

The hypothesis that blotchy ripening (BR) of greenhouse tomatoes (Lycopersicon esculentum Mill.) was associated with a cumulative effect of alternating periods of bright sunshine and cloudy weather was tested in controlled environment chambers. Temperatures were programed to give diurnal changes between 11.7 C/26.7 C night/day representing sunny days, and 11.7 C/21.2 C night/day for cloudy days. The two levels of light were (1) 18,299 lx for sunny days, and (2) 16,656 lx for cloudy days. These two factors were combined in four regimes to represent (1) sunny-day temperature and light; (2) sunny-day temperature and alternate weeks of sunny-day and cloudy-day light; (3) alternate weeks of sunny-day and cloudy-day temperature and sunny-day light; and (4) alternate weeks of sunny-day temperature and light, and cloudy-day temperature and light. Four series of plants showed a common trend. Consistent sunny-day temperature and alternating weeks of sunny or cloudy-day light produced the highest incidence of BR. Alternating weeks of temperature levels with consistent sunny-day light produced less BR but not significantly so. When sunny-day temperature and light were alternated weekly with cloudy day conditions, there was a reduced percentage of BR and less severe symptoms. This regime suggests a compensatory effect when temperature is varied directly with changes in light intensity. The regime for consistent sunny-day temperature and light gave the lowest BR incidence with mild symptoms.

The paper proposes tortuosity as a physical concept particularly useful to interpret internal diffusivities in terms of biofilm structure. Results from different authors are presented showing how average effective diffusivities in biofilms (measured with inert tracers) vary with the fluid velocity: in the case of biofilms formed under turbulent flow conditions, an increase in fluid velocity corresponds to a decrease in the diffusivity, although sometimes this decrease is very slight; however, in laminar flow situations, no common trend is found from research group to research group.

The period of very rapid growth in the industrial world which had begun towards the middle of 1972 was over within a year. Between the first quarters of 1972 and 1973 the aggregate output of the OECD countries increased by about 7½ per cent. Since then, however, the rate of growth has probably been halved.
