Lack of financing. Tax revenues are shrinking in many cities, making infrastructure projects increasingly difficult to finance. In fact, some cities have been forced to implement austerity measures – such as furloughing employees one day a month or cutting back on travel and discretionary expenses. Yet if those cities remain old-fashioned while others modernize, they will suffer even more, since cities must now compete globally. Fortunately, new financial models are emerging. And payment innovations like e-Procurement or electronic benefits can help cities reduce costs and free up money to invest in infrastructure and other improvements. Some of them require little or no upfront capital from the city. Instead, the city “rents” its solution as it goes. And performance contracts and shared revenue models between the city and solution vendors provide cities with attractive financing solutions. What’s more, many smart city solutions have a rapid payback so that they save money over the long run. In many cases, the technology can actually improve the city’s economic return.
