DESCRIPTION:*This paper investigates sectoral reallocations in an economy w
 here climate policy is uncertain. To this end\, it develops a Dynamic Gener
 al Equilibrium model with two sectors  - a polluting one and a non-polluti
 ng one\, along with climate externality and endogenous firm entry. Climate 
 policy uncertainty stems from the possibility that the government may intro
 duce a carbon tax in the next period. I show that\, compared to a scenario 
 without climate policy uncertainty\, the probability of implementing carbon
  taxation prompts entrepreneurs to curtail investment in polluting firms' e
 ntry while promoting entry into the non-polluting sector. Through general e
 quilibrium effects\, these sectoral reallocations deteriorate welfare\, gen
 erate a drop in economic activity\, and increase CO$_2$ emissions. I provid
 e additional empirical evidence through a VAR model that supports these res
 ults. Overall\, this paper points out the economic and environmental costs 
 of climate policy uncertainty.**This paper studies the emergence of violenc
 e in legal markets\, with a particular focus on the informal commuter trans
 port sector in South Africa\, where minibus taxis are integral to urban mob
 ility. Despite being a legal sector\, the taxi industry is plagued by signi
 ficant and persistent violence\, imposing substantial social costs. Using n
 ovel administrative data from the government’s operating license system\,
  route-level pricing information\, and a unique dataset of taxi-related vio
 lence compiled from print and online media\, I examine the interplay betwee
 n competition\, firm growth\, and violence. I leverage variation from a sud
 den decline in rail service quality to estimate the effect of local demand 
 shocks on taxi-related violence in a difference-in-differences framework. T
 he taxi associations most positively affected by this demand shock experien
 ce both a large growth in their membership and substantial increases in vio
 lence. The results are interpreted through the lens of contest theory\, hig
 hlighting that even legal but informal markets can suffer from violence due
  to failures in contract enforcement\, akin to those observed in illegal ma
 rkets.\\n\\nContact: Philippine Escudié : philippine.escudie[at]univ-amu.
