    Prices versus Quantities versus Bankable Quantities

    Quantity-based regulation with banking allows regulated firms to shift obligations across time in response to periods of unexpectedly high or low marginal costs. Despite its wide prevalence in existing and proposed emission trading programs, banking has received limited attention in past welfare analyses of policy choice under uncertainty. We address this gap with a model of banking behavior that captures two key constraints: uncertainty about the future from the firm’s perspective and a limit on negative bank values (e.g., borrowing). We show conditions where banking provisions reduce price volatility and lower expected costs compared to quantity policies without banking. For plausible parameter values related to U.S. climate change policy, we find that bankable quantities produce behavior quite similar to price policies for about two decades and, during this period, improve welfare by about a $1 billion per year over fixed quantities.

    Prices versus Quantities versus Bankable Quantities

    Welfare comparisons of regulatory instruments under uncertainty, even in dynamic analyses, have typically focused on price versus quantity controls despite the presence of banking and borrowing provisions in existing emissions trading programs. This is true even in the presence of banking and borrowing provisions in existing emissions trading programs. Nonetheless, many have argued that such provisions can reduce price volatility and lower costs in the face of uncertainty, despite any theoretical or empirical evidence. This paper develops a model and solves for optimal banking and borrowing behavior with uncertain cost shocks that are serially correlated. We show that while banking does reduce price volatility and lowers costs, the degree of these reductions depends on the persistence of shocks. For plausible parameter values related to U.S. climate change policy, we find that bankable quantities eliminate about 20 percent of the cost difference between price and nonbankable quantities.welfare, prices, quantities, climate change
