梅福券
原页面：MEFO Bills
MEFO Bills is a 
德国 国家精神.
MEFO bills were promissory notes created by Hjalmar Schacht in 1934 to enable the government to fund rearmament, acting through the balance sheet entity Metallurgische Forschungsgesellschaft to hide this rearmament from French and British eyes. It also allowed the government to run a great deficit and procure billions of Reichsmarks worth of funds without devaluing the currency. These bills were supposed to mature in six months, after which their recipients would have to be paid and would cause mass inflation, but historically the German government delayed the problem by extending the bills indefinitely. This contributed to part of the reason Germany initiated the war as soon as they did with the ultimate goal of obtaining enough resources for economic self-sufficiency.
This national spirit is designed to represent the state of the German economy, emulating the rapid rearmament in the period of the Four Year Plan and the economic pressure they faced. As such, its main focus is buffing military related construction as well as compelling the player to start the war and solve the economic problem through conquest. Otherwise the player has to abandon it from the start and rebuild the economy from scratch.
MEFO Bills variants
Player started the game with 
梅福券, as the game progresses the national spirit can evolve into different variants depending on player choices.
There are 3 different variants of the national spirit it can evolve into: 
Economy of Conquest, 
Recovering Economy, and 
Wirtschaftswunder
MEFO Bills mechanic
German national focus features 2 different paths for its Economy focus tree: 
Prioritize Economic Growth和
四年计划. MEFO Bills will be modified and evolve in accordance to which path the player chooses.
Prioritize Economic Growth path
In Prioritize Economic Growth path, 梅福券 will transform into Recovering Economy with heavy penalty. The economy will be ruined from the start, requiring the players to slowly rebuild economy back up stronger than ever, eventually completing 
Wirtschaftswunder and evolve Recovering Economy into Wirtschaftswunder before extensive war production begin.
- The national spirit after fully developed along this path would gain these benefits (without other focus trees and modifiers):
Fully developed with <14% 
世界紧张度 and not at war yet:
Fully developed with >30% 世界紧张度 but not at war yet:
Fully developed when at war with Major country:
The Four-Year Plan path
In 四年计划 path, 梅福券 will grow more powerful rather quickly at the cost of looming burdens on the economy that can only be delayed, forcing the players to go to war sooner or later. At the start of the war players will have a choice to transform MEFO Bills into Economy of Conquest and unlock more measures to buy time. Once enough resources are obtained, players can complete 
实现自给自足 to evolve Economy of Conquest into Wirtschaftswunder, granting further buff and solving the economic burdens permanently.
In addition, a new national spirit 
Wehrwirtschaft would be added in this path to provide buffs that mainly involves becoming self-sufficient on resource, especially 
石油和
橡胶.
Two unique laws, 
自给自足和
总体战, would also become available. 自给自足 offers a small buff in construction and research with very little resource to market and will be further improved after completing 实现自给自足, provides stronger buff with no resource to market. 总体战 can be seen as a stronger version of 
全面动员, provides more buff on construction and less penalty on 
可招募人口 (and can even increase it with Woman in the Workforce Decision).
- The national spirits after fully developed along this path would gain these benefits (without other focus trees and modifiers):
Fully developed when not at war yet:
Fully developed when at war with Major country before 实现自给自足 (with 
维希法国 formed and them having 国家精神 
Occupation costs):
Fully developed after 实现自给自足:
Fully developed Wehrwirtschaft:
It's worth mentioning that apart from selecting national focus, player can also get rid of MEFO Bills and turn it into Recovering Economy by activating 
Cancel MEFO Bills decision, though it's not recommended to do so.
Comparison between the two paths
Here's the comparison between the two paths, accounting for Wehrwirtschaft and state of war while excluding other national focuses and factors:

Consumer Goods Factories factor mechanic
Consumer Goods Factories factor (CGFF) is the main antagonist when dealing with the MEFO Bills system. It represents the cost of channeling every resource into rearmament instead of conventional economic development. CGFF will further increase the Consumer Goods granted by the Economy Law, limiting the number of 民用工厂 available for construction and repair.
以下是关于CGFF的公式：
消费品总量=经济法案赋予的消费品·（1+CGFF）
In some cases CGFF can go into the negatives. This will in turn reduce the current consumer goods needed multiplicatively. Thus, there's not need to worry about overdoing it while managing CGFF.
Managing CGFF in "Prioritize Economic Growth" path
If you choose Prioritize Economic Growth path, apart from losing the benefit of 梅福券, a hefty CGFF penalty would be dumped on you almost immediately. Managing CGFF in this path is pretty straight forward, albeit slow. All you need to do is patiently progress through the focus tree as most of the focuses would reduce CGFF by a bit, in addition to other benefits like new factories. Eventually, after completing Wirtschaftswunder the CGFF penalty would be gone completely.
- The following are the national focus in this tree that will reduce CGFF:
| 国策 | Consumer Goods Factories factor reduction |
|---|---|
 Currency Reforms |
-20.0% |
 Lower Taxes |
-15.0% |
 Abolish Price Controls |
-15.0% |
 Agricultural Reforms |
-10.0% |
| Wirtschaftswunder |
-15.0% |
Managing CGFF in "The Four-Year Plan" path
Things get a lot more complicated if you choose 四年计划 path. CGFF started at 10% but would slowly increase every month. If CGFF reached 100%, apart from Consumer Goods, additional penalties would be applied with its severity depending on certain focuses. The only way to stop the growing CGFF permanently is by completing 实现自给自足, which requires a lot of work. So you must rely on various methods provided in the focus tree to delay the growth and buy time.
Price Control Measures
After completing 
Institute Price Controls, not only will CGFF growth be reduced by -0.5% per month, but you'll also unlock 
Price Control Measures decisions to cut down CGFF numbers directly. Apart from reducing CGFF, some decisions may grant benefits while others may incur penalties. These decisions have the advantage of being available without being in war. However, each of them can only be activated once so they can only buy time for you to prepare for an inevitable war.
- The following is the list of Price Controls Measures decisions:
| Price Control Measures
|
|
前置条件 | 效果 |
|---|---|---|---|
| Launch Guns before Butter Campaign | 30 | 消费品工厂系数：-5.0% Gain Base | |
| Launch Arbeit und Brot Campaign | 30 | 消费品工厂系数：-5.0% Change in popularity in current ruling party: +2.50% | |

War support: 
Opinion of Economy of Conquest
When you're in a state of war, no matter if you declare it or being declared on, the event The Future of the German Rearmament Program will show up giving you a choice on whether you want to continue rearmament or not. Choosing Rearmament has always been our goal will transform 梅福券 into Economy of Conquest, which will inherit most of the benefits including those upgraded via focus. Choosing The program is too expensive is highly discouraged unless you plan to choose Prioritize Economic Growth path, as it'll turn 梅福券 into Recovering Economy, incurring heavy CGFF penalty without any short-term means to lower it and impeding your efforts on completing 实现自给自足 if you choose Four-Year Plan path.
One crucial thing to note is that some national focuses in this tree (namely 
Establish the Reichswerke, 
Seize Foreign Industries, Coal Liquefaction, 
Subsidize Hoesch-Benzin, and 
建立布纳工厂) will add additional CGFF upon completion. However, if you complete them before the war started then these additional CGFF will be removed upon converting into either Economy of Conquest or Recovering Economy. So make sure you complete as many of these focuses as possible before going to war.
Seize Gold Reserves
Economy of Conquest will also unlocks new decisions to manage CGFF: 
Seize Gold Reserves. To seize a country's gold reserve, it first needs to capitulate to you or one of your subject, then you can spend 25 to seize its gold reserve and reduce your CGFF. How much CGFF it can reduce is based on target country's total amount of 军用工厂, 民用工厂, and 海军船坞 in its core territory (not counting its subjects) that's under you or your subject's control (not counting your ally). Only countries in 欧洲 can be seized, and each country's gold reserve can only be seized once.
- The following is the formula calculating the effect of Seize Gold Reserves:
CGFF reduction=\frac (Military factories in target's core + Civilian factories in target's core + Naval dockyards in target's core)200
After seizing gold reserve, the state modifier 
Overburdened State will be added to all of the affected states under your occupation for 90 days, which will incur the following penalties:
- Local factory number: -25%
- Resistance growth speed: +10%
- Compliance gain rate: -10%
- Local available resources: -25%
- Local construction speed: -25%
Completing 
Anschluss peacefully will automatically reduce CGFF with 
奥地利's gold reserve. The reduction amount is calculated with the same formula as Seize Gold Reserves but no penalties of Overburdened State will be applied. The same goes for completing 
Fate of Czechoslovakia peacefully and automatically reduce CGFF with 
捷克斯洛伐克's gold reserve.
Vichy France Reparation
If you form 维希法国, they will pay you war reparation and your CGFF growth will be reduced by -0.5% per month as long as they have the 国家精神 Occupation costs. However, this reduction will stop if 维希法国 no longer has Occupation costs or if 维希法国 no longer exists.
Occupied Territory
The monthly growth of CGFF will increase with the more non-core territory you conquered. This represents diverting military resource into occupation instead of armament and combat. Despite the description, the increase is not calculated based on the number of states, but based on the amount of 军用工厂, 民用工厂, and 海军船坞 in non-core states directly occupied by you (not counting your subjects). The number is rounded in 0.5% interval and the total monthly growth is capped at 5% per month.
- The following is the formula calculating the effect of occupation on CGFF growth:
Total CGFF grwoth=base CGFF grwoth+\frac (Military factories occupied + Civilian factories occupied + Naval dockyards occupied)50
Since CGFF growth does not count the factories controlled by your subjects, setting up puppets can help avoiding the penalty in your conquest. You can set up puppets normally through Compliance system, but a more efficient way is completing 
Uplift the Rosenberg Office and setting up puppets through 
帝国专员辖区 system.
Once you conquered the required capital state the decision to set up the subsequent 
Reichskommissariat would become available, allowing you to set up puppets immediately without having to wait for Compliance level. Any newly conquered territory which should've belonged to established Reichskommissariats would automatically be transferred to them, minimizing CGFF penalty and micromanagement. Initially only 欧洲 can set up Reichskommissariats, but other continents would become available after completing subsequent national focuses.
Apart from convenience, there are other benefits for utilizing this system. Each Reichskommissariat being set up would strengthen Alfred Rosenberg by a bit, which would provide nation wide buff on benefiting through subjects. The Reichskommissariats set up this way would start with a boost of initial Compliance, but they have no core on their territory meaning they're still susceptible to Resistance.
实现自给自足
The ultimate goal of 四年计划 path is to aquire enough resources to complete 实现自给自足, which would completely remove the CGFF penalty and provide even more benefits, including buffing 自给自足. The resources must be within the territory of you or your subjects (not counting your ally). Resources spent on production and export still counts, but resources imported from other countries, including your ally, don't count. Don't forget you need to control all of your core states as well.
The followings are the required resources:
Once completed, Economy of Conquest will evolve into Wirtschaftswunder and CGFF will be set to 0% permanently.
MEFO Bills Strategy
MEFO Bills system provides drastically different mechanics based on the path you choose that'll suit players with different playstyle. From a more relaxed, late-game booming strategy that allows you to slowly build up, to a more aggressive, early rushing strategy with the aim of crushing the opponents before they have time to grow.
Prioritize Economic Growth path is suitable for new players and those who prefer booming. This path is less taxing on new players as it requires less micromanagement and provides more room for error. Since you couldn't produce much equipment in early stages anyway, you can follow standard procedure and focus on developing technology, building economic structures and doing other preparation that doesn't cost too much equipment. As you are quite vulnerable militarily during this stage you should avoid starting or joining the war, only send some attache and a few volunteers to earn some XP. Two focuses are locked behind 1939 technologies, so feel free to develop other branches of national focus once you hit the hurdle to no waste time on ahead-of-time penalty. By the time you complete Wirtschaftswunder, 世界紧张度 should be high enough for the remaining focuses. Complete the focus immediately and rush military factories to catch up with other countries as soon as possible. By this time newer models of tanks or other equipment should become available so you can ignore 1936 or other old models in favor of producing newer models. This path provides more 民用工厂, a lot of free 建筑位 and better Construction Speed buffs that benefit not only factories, but all buildings including infrastructures, railways, forts, research facilities and many others that The Four-Year Plan path doesn't provide, giving you a more balanced & productive late game economy as long as you can protect them.
四年计划 path is suitable for experienced players who excel at combat and prefer starting the war as soon as possible. Your military will be ready sooner, allowing you to both rush your opponents before they are fully developed and prevent others from rushing you. This is especially important if you're playing multiplayer or non-historical AI. Be warned though as you'll be faced with a lot of pressure in this path, so it's advised to make a plan before you start. An experienced player can ready their army in 1938/39 quite comfortably in this path, while in the other path it might be delayed to 1940s or even later. As you have good production on equipment early on, you should exercise your military frequently and send as many volunteers as possible. This will improve the quality of your troops and grind tons of XP, allowing you to rush doctrines & technologies as well as design better templates. Use price control decisions strategically to maximize the benefit and avoid stacking the penalties together. Although rushing Anschluss has its benefits, it's also worth it to let 奥地利 & 捷克斯洛伐克 build up more factories. The more they build, the more you'll get after annexing them and the more CGFF they can reduce. If there's some spare time, you can delay the war for as long as possible if you wish as the intelligence bonus of MEFO Bills will be lost upon turning into Economy of Conquest, but you'll still be forced into war eventually after exhausting all other options to lower CGFF. In this path you'll want a swift victory and avoid dragging out because the clock is still ticking before your economy gets crushed by the heavy penalty of CGFF, so don't forget to seize gold reserves before creating the Reichskommissariat. Just be mindful of resistance and avoid seizing too many countries at the same time. Resource-rich states are priority targets as the resources required to remove CGFF are quite steep. In normal circumstances you would need to conquer either Soviet or Allied colonies to get enough resources, but your industry and unique laws will help you with this mountainous task. Even though the maximum possible factories in this path are fewer than the Prioritize Economic Growth path, construction of 军用工厂 is much faster in this path and each factory provides a larger bonus in output and is much more resistant to enemy bombing, which will save lots of time on building and repairing. Lack of 民用工厂 can be somewhat compensated by selling surplus equipment into the arms market. The unique laws also allow you to be more efficient with 人力 and resources. Wehrwirtschaft can help you achieve 石油和橡胶 independence against embargo and blockade. Apart from warfare, you should also build up resource-producing states as it can not only help with production but also help you meet the requirements. Eventually, after completing 实现自给自足, the burdens will be gone and the production will skyrocket, which allows you to take your time building up and researching super weapons to challenge other superpowers such as 
美国.
