1.A firm produces electrically-assisted e-bikes. Currently, it produces a hybrid (“H”) model,which recharges the battery using the cyclist’s peddling energy. It has recently developedplans to switch to producing a plug-in (“P”) model whose battery must be charged froman EV charging socket. The firm is aware that the government is thinking about subsidisingenhancements to the UK’s charging infrastructure, which would increase demand for theP model – this decision will be taken at the beginning of year 2, will take effect immediatelyand cannot be reversed. Currently, the firm estimates the associated costs and revenuesas shown in the following Table.
