The study checks association between the macroeconomic factors and corporate investment decision by using 10 years of data (2007–2016) of 12 Asian countries. There exist the series of studies, which discuss the firm‐level determinants of investment but very few studies have found the relationship between macroeconomic factors and corporate investment. So, with specific data set, this study is an attempt to fill this instant gap by exploring the relationship between macroeconomic factors and firm capital investment. GMM approach uses for estimation purposes. The results imply that increases in inflation rate decrease the investment due to increment in future cost of investment. Similarly, high interest rate decreases the corporate capital investment due to opportunistic options of early returns by investing in high interest income securities. The firms from high GDP growth countries carry higher investment level owing to business acceleration. However, the firms from high FDI inflow countries bear the low investment opportunities attributed to suppressed fierce competition. The countries having developed financial sector encourage their firms to invest more in banking securities instead of investing in physical long‐term investment, that is, investment in fixed assets due to professional management of funds by financial institutions and low substantial risks. Briefly, the findings of the study recommend that the corporate managers should focus on economic sensitivity while making decisions about any potential investment.

This Letter demonstrates a simple method to achieve underwater anisotropic oil-wetting using silicon surfaces with a microgroove array produced by femtosecond laser ablation. The oil contact angles along the direction perpendicular to the grooves are consistently larger than those parallel to the microgroove arrays in water because the oil droplet is restricted by the energy barrier that exists between the non-irradiated domain and the trapped water in the laser-ablated microgrooves. This underwater anisotropic oil-wetting is able to be controlled, and the anisotropy can be tuned from 0° to ∼20° by adjusting the period of the microgroove arrays.
