This paper investigates how trading frictions vary with the thickness of the asset market by examining patterns of asset allocations and prices in commercial aircraft markets. The empirical analysis indicates that assets with a thinner market are less liquid—i.e., more difficult to sell. Thus, firms hold on longer to them amid profitability shocks. Hence, when markets for assets are thin, firms' average productivity and capacity utilization are lower, and the dispersions of productivity and of capacity utilization are higher. In turn, prices of assets with a thin market are lower and have a higher dispersion. (JEL A12, L11, L93)

It has long been thought that traction exerted by filopodia of secondary mesenchyme cells (SMCs) is a sufficient mechanism to account for elongation of the archenteron during sea urchin gastrulation. The filopodial traction hypothesis has been directly tested here by laser ablation of SMCs in gastrulae of the sea urchin, Lytechinus pictus. When SMCs are ablated at the onset of secondary invagination, the archenteron doubles in length at the normal rate of elongation, but advance of the tip of the archenteron stops at the 2/3 gastrula stage. In contrast, when all SMCs are ablated at or following the 2/3 gastrula stage, further elongation does not occur. However, if a few SMCs are allowed to remain in 2/3-3/4 gastrulae, elongation continues, although more slowly than in controls. The final length of archenterons in embryos ablated at the 1/3-1/2 gastrula stage is virtually identical to the final length of everted archenterons in LiCl-induced exogastrulae; since filopodial traction is not exerted in either case, an alternate, common mechanism of elongation probably operates in both cases. These results suggest that archenteron elongation involves two processes: (1) active, filopodia-independent elongation, which depends on active cell rearrangement and (2) filopodia-dependent elongation, which depends on mechanical tension exerted by the filopodia.

AbstractThis reply to Botte (2019, Estimating normal rates of capacity utilization and their tolerable ranges: a comment on Mark Setterfield, Cambridge Journal of Economics, forthcoming) responds to criticisms of the methods used to estimate the normal rate of capacity utilisation and a tolerable interval of variation in the actual rate of capacity utilisation around the normal rate in Setterfield (2019a, Long-run variation in capacity utilization in the presence of a fixed normal rate, Cambridge Journal of Economics, vol. 43, no. 2, 443–63). It concludes with some further reflections on the concept of corridor instability.

A monetary cash-in-advance model is known to be prone to real indeterminacy if the intertemporal elasticity of substitution in consumption is sufficiently low. Moreover, if the model features habit formation in consumption, the scope of indeterminacy increases substantially. This paper shows that many of the nominal frictions and real rigidities commonly used in the New Keynesian paradigm act to decrease the scope of this indeterminacy. These frictions include stickiness in prices and wages, adjustment costs in investment, and variable capacity utilization. When they are all used together in the model, the problem of indeterminacy nearly vanishes, even when habit formation in consumption is allowed.

The role of the planarian neoblast as a totipotential stem cell has been discussed in the literature for well over a century (cf. Brøndsted's excellent review, 1955). It remained a matter of strong debate until 1949 when Dubois demonstrated conclusively the migration of neoblasts (through regions depleted of their neoblasts by radiation) to the surface of a wound. She showed that the onset of regeneration was delayed until the neoblasts reached the wound area, and that once they had arrived regeneration took place at the normal rate with the neoblasts actively dividing in and just posterior to the blastema. Since then many authors (the Brøndsteds, Stéphan-Dubois, Pedersen, Lender, the Benazzis) have studied the histochemistry, the distribution, and the factors which influence differentiation of the planarian neoblast in several species. Only Brøndsted & Brøndsted (1961) have reported on the total number of neoblasts in a planarian.
