When crowds arrive and hotels fill up, a city appears to be growing. Yet revenue generated by a festival and the additional economic benefit left in the community are different figures. The economic contest over a sporting event begins outside the stadium and continues after the closing ceremony.

* Visitor numbers alone cannot determine the success of a major sporting event. Spending newly attracted by the event must be distinguished from shifts in existing spending.

* The economics of hosting depend on how much new stadium and transport construction is required. The use of existing facilities and operating costs after the event must be considered together.

* Global attention offers an opportunity to introduce a city, but it does not guarantee long-term growth. A process is needed to turn first visits into return visits and continuing commercial relationships.

* Even when revenue rises across a region, residents and businesses do not all benefit equally. Where the gains remain and where the costs fall must be examined separately.

* A successful hosting strategy plans for life after the event before the bid is even won. The lasting legacy should be a network of local economic relationships that keeps functioning, rather than a brief surge of excitement.

Imagine a day when a World Cup match is taking place. People in team jerseys gather outside the station, and different languages fill the restaurants. Accommodation bookings fill up, and queues outside shops grow longer than usual. The city's atmosphere changes in an instant. Faced with this scene, the claim that sport revitalizes the local economy feels intuitively persuasive. Where people gather, money moves too.

But a local economy's report card cannot be completed with a single photograph of a bustling street. Its meaning depends on where spectators have come from, what they spend money on, and who receives that money. If visitors would have come to the city anyway, it is difficult to count all their spending as an effect of hosting. If residents cut other leisure spending to buy match tickets, the destination of money within the region may simply have changed.

Published by Knowledge at Wharton, the Wharton School's business publication, on June 9, 2026, "How Sports Are a Local Growth Engine" introduces an expert panel discussion on Philadelphia's hosting of major events. Moderated by Wharton finance professor Kevin Kaiser, the discussion brought together representatives of a local professional soccer club, a tourism marketing agency, and a sports event recruitment organization. At its center were strategies for turning sports spectators into long-term customers of the city and the challenge of managing hosting costs.

Such a discussion must, however, be distinguished from a retrospective assessment of how much an event has grown the local economy. The goals and forecasts of those preparing to host help explain their strategies, but they do not in themselves provide evidence of a return on investment. The original article also notes the need for economic evaluation before and after the events. Asking under what conditions expectations become results is the starting point for reading this discussion.

What is needed from here is a connection between the language of celebration and the language of accounting. Visitors' enjoyment and residents' pride are forms of value a city gains. At the same time, the use of public money requires an explanation proportionate to the amount committed. An event can be both enjoyable and economically beneficial to its host community, but one judgment does not automatically prove the other.

Suppose restaurant revenue rises sharply during a sporting event in a hypothetical city. This is clearly welcome news for restaurants near the stadium. To understand the result for the entire local economy, however, the analysis must go a step further. The size of the additional demand depends on whether the money is newly spent by out-of-town spectators or redirected by residents from other neighborhoods. The central question is less whether money moved than how much more money entered because of the event.

For example, suppose residents spend their entire planned weekend dining and cinema budget on attending a match and eating nearby. Businesses around the stadium gain revenue, but other restaurants and cinemas may lose sales. Adding up individual businesses' gains without examining these shifts risks overstating the effect on the city as a whole. This is why busier tills at the event do not, by themselves, establish that the community's capacity to spend has increased.

Spending by visitors from outside the region requires the same scrutiny. If someone already planning a trip that month merely changes the dates to coincide with a match, part of the increase in event-period revenue may represent sales brought forward from another period. Conversely, if a first-time visitor attracted by the event stays an extra day and visits local restaurants and attractions, the potential for additional spending increases. This is where surveys asking about the purpose and length of a visit can provide more useful information than satisfaction surveys alone.

Demand lost because of congestion must also enter the calculation. If travelers with no interest in sport choose another city to avoid expensive rooms and crowded streets, the host city may gain new customers while losing others. A company planning a business trip might also postpone it. Rather than counting every visitor during the event as a gain, the analysis must compare demand added by the event with demand displaced by it.

This perspective is not a device for diminishing the value of sporting events. Support can become more precise only when the channels through which benefits arise are understood accurately. If visitors stay briefly, connections to nearby attractions can be strengthened; if spending is concentrated inside the stadium, routes into local shopping and dining districts can be developed. Separating the flows of spending reveals opportunities for improvement that a single total-revenue figure conceals.

In competition to host sporting events, the question of what to build can quickly move to the forefront. Large stadiums, spacious plazas, and new roads are highly visible. From an economic perspective, however, the ability to use existing facilities effectively deserves equal weight. The less additional spending an event requires, the smaller the cost-recovery burden, even when the number of visitors and the spending attracted are similar.

Among the strengths Philadelphia's representatives emphasize in the Knowledge at Wharton article are its existing stadiums, transport network, and international airport. Their argument is that the city can accommodate major events using infrastructure it already possesses. Kaiser, meanwhile, reminds participants that hosting carries costs and raises the need to run events like a business. This leads to the broader point that hosting capacity and the economics of hosting must be assessed together.

Applied to decisions in other cities, this changes the order of the questions. Instead of winning an event first and then listing the facilities required, a city can examine its existing assets and everyday demand before choosing a suitable event. An event of the same size cannot offer every city the same opportunity. A city able to use an existing stadium and one requiring extensive new construction face different balance sheets from the outset.

Where new construction is necessary, the calendar after the closing ceremony matters more than opening day. How many days a year will the facility be used, who will operate it, and how will maintenance be financed? Even if every seat is occupied during the tournament, insufficient subsequent use can leave a prolonged operating burden. Securing construction funding alone does not amount to a financial plan covering the facility's entire life.

The same applies to transport infrastructure. Beyond moving spectators quickly during the event, planners must ask how it helps residents commute and make everyday journeys. Facilities that remain useful afterward provide a basis for examining long-term benefits. Yet the full benefits of projects already planned should not be attributed to winning the event. Distinguishing investment added because of hosting from existing plans clarifies the relationship between costs and benefits.

A major sporting event provides a stage on which a city's name can become widely known in a short time. But several steps separate someone who has heard of a city from someone who actually returns. They must become interested in the scenery on screen, search for travel information, compare transport costs, and decide to visit. If a host city wants lasting results, it must turn this chain of connections into concrete work.

Here, a city's brand is about more than logos and slogans. Imagine a visitor who enjoys the match but gets lost returning to the hotel, cannot understand transport directions, and encounters difficulties making reservations. That person's image of the city will likely reflect the experience more than the promotional language. Conversely, easy travel and convenient everyday services create room to discover attractions beyond sport.

It is therefore difficult to treat signage, transport information, accessibility, and transparent pricing as peripheral preparations. These elements shape visitors' experiences and influence how residents cope with the event. If the same investment is useful in everyday life, event preparations can be linked to improvements in city services. What matters is narrowing the gap between a spectacular presentation and the actual experience of using the city.

Methods of encouraging return visits must also be specific. For example, a program could identify visitors' interests within the scope of their consent and provide information about local food, performances, and exhibitions after the match. Offers from local shops that can be used on a future visit are another possibility. These are potential measures, not outcomes whose effectiveness has already been established. They should be adjusted as actual participation and return visits are tracked.

Local businesses face a similar task. They need to examine whether relationships with customers or business partners first encountered during the event can continue, and whether short-term orders can become repeat orders. Long-term urban growth is more closely connected to continuing choices and transactions than to one-off exposure. Making use of an event requires more than a promotional budget that ends with the closing ceremony: it requires people and an action plan to manage the relationships afterward.

The expression "the local economy grew" can make a city sound like a single entity. In reality, a city consists of different businesses and residents. Higher accommodation revenue and the inconvenience experienced by residents facing traffic restrictions do not readily appear in the same table. Shops around the stadium may also fare differently from those outside the event's main routes. A gap can emerge between the regional total and the experiences of the people who make up that region.

The share of money that remains locally must also be examined. It cannot be assumed that all visitors' spending stays within the community. Depending on the structure of transactions, some may be paid to outside operators or suppliers. Other portions may support local procurement and employment. Looking beyond expenditure totals to the share of local procurement and the structure of local business participation therefore allows a more concrete assessment of economic connections.

Costs borne by the public sector require particular attention. Even if private sources finance a substantial share of event operations, services provided by the city can still require staff and budgets. The actual increase in tasks such as additional transport operations, safety management, and cleaning must be examined. Handling them within an ordinary budget does not mean no resources were used. Time and capacity that could have served other work also merit consideration.

Public funds also have alternative uses. To judge the priority of event support, it must be compared with using the same resources to improve transport or maintain everyday community facilities. This does not require every benefit to be converted into money. Values that are difficult to price, such as residents' pride and shared community experiences, can also be debated openly. Such values should not, however, be used to omit explanations of fiscal burdens and opportunity costs.

Broadening local participation requires examining contracts and operating rules before the event. Are procurement packages small enough for smaller firms to participate? Is the allocation of selling space transparent? Are there directions guiding visitors to commercial areas beyond the venue? Routes and information that support residents' everyday journeys are also matters for design. Expanding economic benefits can begin with the conditions for accessing opportunities, rather than with distribution after the event ends.

The expression "growth engine" implies continuity. An engine is a device that keeps generating power, rather than merely making a loud noise once. Sporting events need to be viewed by the same standard. Even substantial spending during an event is better described as a temporary increase in demand if it does not connect to subsequent activity. A judgment of long-term growth requires a longer observation period and different indicators.

To that end, performance criteria can be established before hosting. Alongside visitor numbers and event-period sales, cities can separately record additional overnight stays by out-of-town visitors, local business participation, additional public-sector costs, and subsequent facility use. Resident satisfaction and travel inconvenience can also be surveyed. Placing different indicators side by side helps explain a city's choices better than a single enormous economic-impact figure.

The basis of comparison matters too. If revenue during an event exceeds the previous year's figure, the entire increase cannot automatically be attributed to the event. Prices, economic conditions, the timing of holidays, and other events may all change sales at the same time. Where possible, comparisons should be made with similar periods or other regions, and the assumptions behind impact estimates should be disclosed. Where precise figures are hard to obtain, revealing the range of uncertainty is more useful than making a definitive claim of success.

Evaluation should not stop immediately after the closing ceremony. It takes time to establish whether expanded operations and employment are maintained, whether new commercial relationships continue, and whether facilities are used as planned. Changes in return visits can also be examined separately. If indicators fall short of expectations, the reasons should inform the next event and city policy. When evaluation is merely a promotional procedure, this opportunity to learn is lost.

Criteria for withdrawing or adjusting the scale of an event are also needed when the hosting decision is made. A city can specify which projects will be reduced if costs exceed the original plan, and who will bear the burden if anticipated private funding falls short. Because enthusiasm can make additional spending easier to accept, decision criteria are better established before excitement builds. Aiming for success and preparing for possible failure can proceed together.

A major sporting event can provide an opportunity to showcase a city's assets and build relationships with new customers. Turning that possibility into reality requires more than the scale of the competition. It takes routes that generate additional spending, decisions that make use of existing facilities, commercial arrangements involving local firms, and operations that continue beyond the closing ceremony. The label "growth engine" becomes persuasive only when these conditions are examined.

The result of a match is decided at the final whistle. The city's result emerges afterward. The meaning of hosting becomes tangible when people return, shops continue doing business, facilities are used in everyday life, and the public burden can be explained. The best report card lies less in a photograph of the day with the largest crowd than in the everyday life of a city that keeps moving after the spectators have gone.
